In nature, there are different types and varieties of ageratum. But, unfortunately, not all of them can grow in our latitudes. Plants differ in the size of the bush, the shape and color of the buds.

Popular types and varieties of ageratum

Ageratum is one of the most popular crops, which are increasingly used to create unusual landscape designs.

According to height, the plant is divided into two main groups:

  • medium size (plant stem reaches 30 cm);
  • dwarf varieties (shoots grow about 15 cm).

Types of ageratum that are especially popular:


Ageratum Blue Ball is a drought-resistant species.

Ageratum mexicanis

This type of plant is often called Houston's ageratum. The flower is distinguished by erect stems, which are highly branched at the top. They form a spherical bush from 15 to 60 cm in height. The inflorescences are lush, various shades. They reach 8 cm in diameter.

The most popular varieties:


Also included in this species is the North Sea variety of ageratum. The flower belongs to the low-growing bushes. Its maximum height is about 15 cm. The flowers are beautiful, dark purple.

It's compact annual plant. The bush reaches a maximum of 60 cm in height. Flowering is abundant. The buds begin to bloom in early June. Flowering lasts until frost. The inflorescences are dense, rich blue in color.

This species is excellent for growing in both open ground, and in flowerpots. The flower goes perfectly with different types plants.

At the end of flowering, boxes are formed in which the seeds are located. Grains brown tint, very small.

Dwarf Little Rose

This unique variety, which is a low bush. Like other species, Little Rose has a spherical shape. The inflorescences are colorful and star-shaped. They have a rich pink hue that does not change throughout the entire flowering period.

This variety is often used to form borders. Little Rose is often planted in street flowerpots and hanging flowerpots.

The bush grows up to a maximum of 25 cm. If you water and fertilize it in a timely manner, flowering will occur in the first part of June. Reproduces this type using seeds.

Ageratum red

This is the most unusual variety, which is in particular demand among gardeners. The plant is distinguished by long shoots. The bush grows up to 60 cm tall. The flowers are huge. They are collected in lush inflorescences that have a red tint.

The uniqueness of this variety are the flowers. In this species they are shaggy. Red ageratum looks great in flower beds with other white or pink flowers.

Ageratum Kalinka

This variety has a compact size, which allows it to be grown in indoor flowerpots and outdoor containers.

Kalinka ageratum also develops well in open ground. But to get abundant flowering, it is necessary to pinch the plant in a timely manner. This is the only way the bush will be beautiful and healthy.

There are also yellow species of Ageratum. One of these is the variety Gold autumn. It is a perennial that grows up to 15 cm tall. The inflorescences are large and bright. The leaves are grayish-green, small. Elongated plates.

Yellow varieties tolerate drought well, but love warmth and sun. These flowers are suitable for decorating rocky gardens and borders.

Ageratum Spring Drops

Plants of this type are very popular all over the world. All varieties that are collected in the set have a rich color. The bushes do not grow more than 30 centimeters. All varieties tolerate haircuts well, which is why they are often used for decoration.

Aztec Treasures

This mixture is an annual. The height of the shoots reaches a maximum of 25 cm. The plant blooms profusely until the onset of the first frost. The flowers are tubular and small. The diameter of the inflorescences does not exceed 1.5 cm. The shade of these plants is completely different

All types and varieties of ageratum, which are described above, are beautiful in their own way. If you know the characteristics of each plant, you can purchase the option that best meets the requirements and is most suitable for the chosen landscape design.

Our garden has beautiful species and varieties of ageratum - video

Originally from Central and North America. The ageratum flower got its name from the Latin “ageratos”, which means “ageless”, but in our country its other name has taken root – “long-flowered”. This quite accurately describes the plant, because the flowering of ageratum begins in June and lasts until the first frost, and tall varieties, actively used in floristry, are able to maintain freshness for a very long time when cut without additional care.

Ageratum grows and branches well, so landscape design it is used to create hedges and borders, the branches and stems of which, intertwined, create a monolithic green fence. It is grown primarily for its fluffy flowers, reminiscent of pompoms, which are collected in dense inflorescences. The palette is most often shades of blue, but there are varieties of white, pink, red and burgundy; when planted en masse, it forms an almost continuous flowering “carpet.”

Ageratum is often planted along the edges of flowerbeds with zinnia, cosmos, cleome, verbena, where it will look bright as a beautiful lush spot. Ageratum also goes well with marigolds, evening primrose, balsams, calendula, snapdragon, asters and roses. It is often used to simulate a dry stream or pond in an area.

Advice! Together with marigolds, it is good to plant it at the roots clematis, they will create the coolness necessary for the clematis roots.

It is also used in single plantings; it will look especially impressive against the backdrop of a well-groomed, uniform green lawn. Low-growing varieties of ageratum tolerate growing in flowerpots well, so they are often used for decorating balconies and decorations. patio, gazebos, recreation areas and entrance areas.

Ageratum: types and varieties

Despite the fact that ageratum is a perennial, in our climatic conditions it is grown as an annual. For the same reason, out of more than 50 various types It is possible to grow only a few species of ageratum.

Ageratum mexicanis

Another name is Houston's ageratum, a plant with numerous erect, highly branched stems, reaching a height (depending on the variety) from 10 to 50 cm. The leaves are oval, rhombic or oval, jagged along the edge, rough. The flowers are fragrant, narrow-tubular, small, collected in small (1-1.5 cm in diameter) inflorescences of the basket. In turn, these basket inflorescences are collected into complex corymbose inflorescences reaching up to 10 cm in diameter. Many varieties differ in shades of flowers, flowering times and bush height, the most popular are:

  • Alba is a compact, only about 20 cm high, spherical bush with white dense inflorescences
  • Blau Kappe is a low (20-30 cm) compact hemispherical bush with densely pubescent dark green shoots. The inflorescences are medium-sized (5-6 cm in diameter), loose, with short stigmas, lilac-blue. Late variety - flowering begins at the end of June and lasts until October
  • Blausternchen is a very low (10-15 cm) compact bush with thin, densely pubescent, dark green shoots with a slight purple bloom. The inflorescences are few-flowered, loose, the baskets are small (up to 1 cm in diameter), blue with a characteristic lilac tint, and the buds are dark purple. Early variety, flowering begins in early June and lasts until October, requires watering
  • Blue Mink is a low (25-30 cm) columnar compact bush with thick, weakly leafy, strong shoots. The inflorescences are large (up to 2.1 cm in diameter), dense, lilac-blue. Drought resistant. According to flowering time - medium grade, flowering begins in mid-June and continues until October.

Ageratum blue

Another name is “Blue Mink”, this variety received because of the specific shade of the flowers - pale blue, similar to mink fur. This is a low (up to 25 cm) bush with large (5-8 cm) inflorescences that cover the plant almost completely.

Plant ageratum (lat. Ageratum) belongs to the genus of the Asteraceae family. Its representatives are found mainly in North and Central America, as well as in Eastern India. The name of the plant comes from the Latin ageratos, which means “ageless,” and in fact, ageratum remains fresh for a very long time when cut. In Europe, ageratum became widespread in the 19th century; in our country it is called “long-flowered”. It is grown in gardens for its fluffy flowers, similar to pompoms, collected in dense inflorescences, most often in a blue palette of shades; in addition, it is completely unpretentious in care. There are about 60 species of ageratum.

Ageratum flower - description

Ageratum is a small bush with triangular, oval or diamond-shaped leaves of a lush green color with a serrated edge. The upper leaves are alternate, sessile, and the middle and lower leaves are opposite, on petioles. Numerous erect, pubescent stems reach a height of 10 cm to 60 cm. The flowers are small, fragrant, bisexual, collected in small inflorescences-baskets from one to one and a half centimeters in diameter, which in turn form complex corymbose inflorescences - they are not only blue and purple, but also white, and pink shades. The fruit of Ageratum is an elongated wedge-shaped pentagonal achene.

One gram contains approximately 7 thousand small seeds that remain viable for 3-4 years.

In our climatic conditions, ageratum is grown as an annual plant, since it is very thermophilic. Ageratum looks great in a flowerbed, in a garden bed, and is used to create carpet compositions. Plant partners of ageratum include other annuals - snapdragons, marigolds, calendula.

Growing ageratum from seeds

Sowing ageratum seeds

Ageratum is usually propagated by seed. Ageratum seeds are sown in the second half of March in boxes with soil consisting of equal parts from humus, sand and peat. Small seeds are carefully sprinkled on top with the same soil and covered with glass or film. You need to keep the greenhouse in a room where the temperature is not lower than 15 ºC, and ventilate it daily.

It is very important to keep the soil slightly moist at all times, so be sure to sprinkle the soil as it dries.

The seedlings usually germinate in a couple of weeks, and from the moment they appear, the box can no longer be covered with glass or film.

Ageratum seedlings

After the seedlings have two pairs of true leaves, they need to be planted more spaciously. Ageratum seedlings need to be picked twice, and during the second picking, each sprout should be planted in a separate pot or cup. The air around the seedlings should be dry and the soil moist. Watering ageratum is carried out only in the morning. Two weeks before planting, take the plant out to open air for acclimatization, but if there is a threat of frost, be prepared to cover them.

Planting ageratum

Ageratum is planted in the ground when night frosts are left behind. Choose a site that is protected from drafts and brightly lit by the sun - if you plant ageratum in the shade, the shoots will begin to stretch, and instead compact bushes you will have disheveled bushes that bloom haphazardly. The soil is preferably well-drained, nutritious, light and not acidic, but ageratum is not capricious in this matter. Before planting, thoroughly loosen the soil, dig holes at a distance of 10-15 cm from each other and plant the seedlings at the same depth at which they grew in seedling boxes or pots. The ageratum will bloom in about two months.

Ageratum care

Caring for ageratum involves watering, fertilizing, loosening the soil and weeding. Water ageratum should be abundantly, but not excessively; after watering, along with loosening the soil, remove the weeds. They feed plant with humic or mineral fertilizers every two to three weeks. Fertilizing with mullein infusion has a good effect on ageratum, but under no circumstances use fresh manure as fertilizer - ageratum does not tolerate it.

How to grow cineraria - proven tips

Try not to overfeed the plant, otherwise it will turn lush and not bloom. Remove faded inflorescences in a timely manner. If you want the ageratum to bloom profusely and beautifully, you should trim it as necessary, leaving only a few internodes on the stem. Usually, after such pruning, ageratum grows quickly and blooms more luxuriantly.

Ageratum after flowering

On the eve of the first frost, replant the most beautiful bushes ageratum in flower pots and bring them into the house, onto the balcony or veranda - they will decorate your home until the end of autumn, and maybe even in winter. In March, you can take cuttings from these bushes and root them so that you can plant them in the garden after frost.

In general, ageratum - heat-loving plant, unable to bear even the most mild winters. Hiding won't help him either. Therefore, you will have to clear the flowerbed from the remains of ageratum and next spring plant new plants.

Diseases and pests of ageratum

The most weakness ageratum – susceptibility to disease. Most often, ageratums suffer from root rot, and there is no escape from this disease. But by taking preventive measures, namely, choosing light soil for planting ageratum, controlling watering and regularly loosening the soil to slow down the process of evaporation of moisture from the soil, you can prevent the disease. Ageratum is affected by cucumber mosaic and bacterial wilt, and all this is a consequence of improper plant care.

I will repeat my mantra: diseases and pests attack plants when you long time the rules for caring for them are violated. If you strictly follow the rules of agricultural technology, your plants will not be afraid of such troubles.

Protect young plants while they are at home or in the greenhouse from spider mites and whiteflies, but if they appear, you will have to remove damaged leaves and treat the plants with insecticides until the insects die. Later, in the flowerbed, the ageratum may be encroached upon scoops And nematodes, and you will have to work hard to get rid of them.

Types and varieties of ageratum

Since growing ageratum is not difficult, and its decorative value is quite high, it is not surprising that it is so popular among gardeners. We will present to you several popular types and the most attractive varieties of ageratum:

grows up to 20 cm in height, has erect stems, fragrant, white flowers.

Ageratum blue Blue mink

They are small branched bushes with strong shoots 20-25 cm tall. The fluffy inflorescences of a delicate blue shade really look like mink fur, since they cover the entire bush. The diameter of the inflorescences is 5-8 cm.

The Asteraceae family includes many beautiful plants, among which is Ageratum. So unusual name I got the flower because of its characteristics; this plant blooms for a very long time, starting in June and ending with the first frost. Translated from Latin the word ageratos Means ageless. Gardeners have already fallen in love with it and this is not surprising, because the plant has an unusually beautiful appearance and is suitable for decorating not only lawns and flower beds, but also balconies. More information about growing ageratum from seeds will be discussed in this article.

Peru is considered the birthplace of ageratum. This is a perennial plant reaching a height of 20-60 cm. Thanks to its unusual properties, ageratum can delight gardeners with its flowering for a long time, it’s not for nothing that it is popularly called “long-flowered.”

The plant is used in landscape design, so most often it can be seen in gardens country houses. Blooms until the coldest weather and is beautiful appearance made longflower an obligatory guest of various flower exhibitions. The inflorescences have pleasant aroma, which does not disappear for a long time, like the pristine beauty of flowers. What makes ageratum decorative is that its style and stigma are slightly longer than the corolla of the flower. The diameter of the baskets reaches 1.5 cm, and they, in turn, form large inflorescences (up to 12 cm), which evenly cover the entire plant.

On a note! The shape of the leaves, depending on the ageratum variety, may vary. Most often, there are plant varieties with oval leaves, the edges of which have denticles. Ripe fruits contain a huge number of seeds (at least 6,000 seeds per 1 g). The seeds are unpretentious, so they can germinate even after several years of ripening.

Popular plant varieties

There are more than 70 different types of plants, differing from each other in their decorative characteristics (shades of flowers, flowering time, height of the bush, and so on). But not all are used in gardening. Let's look at the most common varieties.

Table. Popular varieties ageratum.

Variety name, photoDescription

Extraordinary beautiful plant with large lilac-blue or white inflorescences. The height of the bush rarely exceeds 30 cm, which is why it looks more collected and compact. This is a late plant as it begins to bloom in the second half of June.

Small bushes up to 15 cm in height are colored with densely pubescent green shoots. The inflorescences of this variety are colored lilac, although plants with blue flowers. The flowering period occurs in June.

One of the most popular ageratum hybrids, distinguished by its short growth (up to 15 cm) and small blue flowers. Flowering begins in early summer.

A strong plant with thick and durable shoots, reaching a height of 30 cm. The diameter of the dense inflorescences is no more than 2.3 cm; they are decorated with flowers lilac shade. This variety begins to bloom in the second half of June.

An unusual variety of ageratum, the inflorescences of which are painted in two shades: light blue petals surround the white core of the baskets. The inflorescences of this plant are quite larger, which makes it excellent option for garden decoration.

Refers to compact varieties of ageratum. Its height rarely exceeds 20 cm, although specimens up to 15 cm are most often found. The color of the buds is dark pink, and the inflorescences that then emerge from them have a pale pink tint.

Sowing time

If you decide to grow ageratum seedlings, then you need to understand that the period between sowing the seeds and the first flowering is at least 60 days. Since this is a heat-loving plant, it is necessary to exclude the possibility of spring frosts at the time of planting seedlings in the soil. Even slight cold snaps can have a negative impact on the flower - this must be taken into account.

On a note! Having carried out simple mathematical calculations, it is not difficult to guess that mid-March is considered the most optimal period for sowing ageratum seeds. Of course, you can sow the seeds at a later period, but this will delay the beginning of flowering a little.

Growing from seeds

Ageratum is perennial plant, but in our conditions there is no need to use it for many years. Propagation can be carried out in two ways - cuttings and seeds, but, having finally weighed the pros and cons, flower growers usually settle on the second method.

On a note! The development cycle of ageratum is accelerated, which distinguishes the plant from its “colleagues”. Thanks to this feature, it is possible to move the sowing period to April-May.

Like any plant, ageratum loves nutritious soil. IN in this case it is better to use slightly acidic or neutral soil, so if you decide to prepare the soil mixture yourself by mixing humus, lime and garden soil, do not forget to add a little - this will reduce the acidity of the soil. Also, do not add too much humus, since its excess will have a bad effect on flowering, making it more sparse.

This all applies only to soil prepared with one’s own hands. Few gardeners do this. It will be much easier to purchase ready soil for flowers in the store, what to do with preparing it.

Nutritious universal soil for vegetables and flowers

Sowing seeds

Step 1. Fill the seedling container (in this case a container) with the soil mixture about 80%. If you want to grow several varieties of ageratum at once, it is better to take a separate container for each of them.

Step 2. Place the seeds from the bag onto a plate. There is no need to use everything, since the seeds are very small and there are quite a lot of them. Half the contents of the package for one container is quite enough. Preliminary preparation there is no need to carry out seeding.

Seeds are poured onto a plate

Step 3. Sow the seeds evenly over the surface of the soil. They have a long shape, so you can easily notice if they have accumulated 5-6 pieces in any place. Use a regular toothpick to push the seeds away from each other. This will be much faster than removing the seedlings later.

Step 4. During the growing process, monitor the soil moisture. At an early stage, humidity can be preserved by placing the container in a special container with a hole made. If you do not provide the seeds with enough moisture, the plant will die in almost all cases.

Step 5. Place the seed container on a windowsill with sunny side. If all are met the necessary conditions for seed germination, you will soon get such friendly shoots.

Transplantation into open ground

In the second half of May, having chosen a clear and warm week (having looked at the weather forecast in advance), begin transplanting plant seedlings in open ground. Place the seedlings in the previously prepared holes, and fill the remaining space with soil, which must be slightly (but not heavily) compacted. The distance between low-growing varieties of ageratum should be no more than 15 cm, between tall ones - up to 25 cm.

On a note! The area where you plant the plants should be sunny, since even slight shading can cause the shoots to stretch. As a result, the flowering intensity decreases. Even though the bulk of the work is behind you, you still have work to do. It's about about caring for ageratum.

Aftercare

Although the plant is considered unpretentious and does not require care, you still need to pay attention to it. But the labor and time spent will not go in vain. As a result, you will be rewarded with lush and vibrant flowering of ageratum.

Top dressing

For feeding you can use not only minerals, but also organic fertilizers. Gardeners also prefer to apply complex fertilizers. This should be done every 3 weeks, and the first fertilizing should be carried out using the minimum dosage of fertilizers. Otherwise, flowering may slow down due to their excess. It is highly not recommended to use manure to fertilize the soil, because it can destroy the ageratum.

Watering

The root system of this plant is very developed, which allows ageratum to extract required quantity moisture from the soil. Therefore, water regularly - every 3 weeks, but at least once a month. During hot periods, the frequency of watering, as well as the amount of water used, can be slightly increased.

Ageratum pruning

To obtain lush and beautiful bushes, it is necessary to periodically trim the ageratum. Leave no more than 4 internodes when pruning to speed up plant development. Before the first frost, you can transplant the flowers into separate pots and grow them in greenhouses or at home. Proper care will allow you to enjoy beautiful flowers throughout the winter.

On a note! With the onset of spring, the bushes can be transplanted into open ground again or the plants can be cut into cuttings, thus rejuvenating them.

Loosening the soil

Regular watering and fertilizing are not the only things that need to be done when growing ageratum. The soil around the plants must be loosened regularly. Since this flower likes to grow in airy soil, this procedure will improve its growth. When loosening, be sure to remove all weeds, as they inhibit the growth of the plant. After completing the next weeding, mulch the soil. This will prevent excessive evaporation of moisture.

Disease and pest control

Like most ornamental plants, ageratum can be exposed various diseases, the most common of which is root rot. Neglect preventive measures will lead to rotting and, as a result, death of the plant. To prevent this from happening, you need to pay attention to the intensity of watering and periodically loosen the soil. Ageratum may also be affected cucumber mosaic, which is also the result of non-compliance with the rules of care.

Seedlings that are still indoors or in a greenhouse must be protected from whiteflies. If these pests do appear, it is imperative to remove the damaged plants and treat the flowers themselves with insecticides. Carry out treatment until all insects are completely destroyed. Over time, when you transplant seedlings into open ground in a flower bed, nematodes or cutworms may encroach on the plants. In this case, you also need to use special means for processing. And remember that correct and conscientious adherence to the rules of agricultural technology will protect your plants from such troubles.

Decorative uses

As noted earlier, ageratum is of great value for landscaping and decorating areas. This is due to long flowering, unpretentiousness and color variety. This combination is quite rare among ground cover ornamental plants.

Ideal for decorating balconies, loggias or borders low-growing varieties ageratum, and tall plants Can be grown for later cutting. If we talk about combination with other colors, then blue varieties ageratum will look great with eschscholzia, zinnia and marigold. In other words, any unpretentious flowers yellow shades.

Video - Germination of ageratum seeds

Ageratum is one of the most “fluffy” herbaceous perennials, which does not have any particularly spectacular greenery or graceful lines, but during the flowering period it captivates with a unique foam of flowers similar to soft pompoms in fairly dense inflorescences. The stems are numerous, strongly branched, erect or erect, pubescent, 10-50 cm tall.

This flower has a number of qualities that are valuable in landscaping: it has a powerful root system, which allows you to tolerate overheating of the soil and its drying out in summer; it blooms for a long time, right up to frost. In addition to growing in flower beds (especially parterres), the plant looks good on sunny balconies, in above-ground containers. It is rarely used as a cut flower, although its sweet, pleasant aroma and tall varieties make it attractive for bouquets.

Growing ageratum from seeds

Ageratum is grown mainly from seeds, but it is also possible vegetative propagation by cuttings. The seeds are quite small (6–7 thousand per 1 g), they remain viable for 3–4 years. Sowing is carried out with both regular and granulated seeds.

To germinate seeds, use a sufficiently moist, light and nutritious substrate, but without excess moisture, pH 5.5–6.5. For pellet seeds, the soil needs to be moister than for regular seeds.

Seeds are sown in March or early April in greenhouses or boxes, without deepening the seeds. The seedlings usually hatch after two weeks, after emergence they are allowed to grow for about 3 weeks and then dived into greenhouses or boxes on a slightly larger

Growing seedlings in cassettes.

distance from each other.

When growing ageratum seedlings, double picking is desirable.. The seedlings do not tolerate dampness. Watering should be done in the morning, and greenhouses should be ventilated frequently. 10-14 days before planting the seedlings, the frames from the greenhouses are removed and covered again only if there is a threat of frost. They are planted in open ground after the end of spring frosts, maintaining a distance of 15-20 cm between plants when planting. Plants bloom 60-70 days after emergence.

Planting and caring for ageratum in open ground

What soil is best to grow in? It grows quickly and develops well on light, neutral, nutritious soils; on too rich soil it develops a large vegetative mass, and the flowering intensity decreases. Does not tolerate raw rocky soils!

When to plant ageratum. Ageratum cannot withstand frosts, even light ones. Therefore in middle lane it is planted in open ground only at the end of May or at the beginning of June, when there is no need to be afraid of them.

The flower usually tolerates transplantation painlessly, as long as the young plants have enough moisture, heat and light during the rooting period. In order to preserve both the first and second, it is advisable to mulch the soil around the plants with peat or humus after planting: water from its surface will evaporate more slowly, and in the event of unexpected frosts, only the top of the plant will die (new shoots will soon begin to grow from the lower part).

Landing scheme. The planting density depends on the variety and type of flower garden. Tall varieties, for example, are planted at a distance of 20–25 cm from each other, and compact, low-growing hybrids - at a distance of 10 cm.

Care: plentiful, but not overwatering, easily tolerates haircuts and pruning, after which it quickly grows back and blooms profusely again; The plant is heat-loving and is damaged even by minor frosts. Regular weeding and loosening. Always cut off faded inflorescences.

Gardeners have the opportunity to grow numerous new varieties of ageratum. Currently, varieties and F1 hybrids differ in inflorescence color, compactness, leaf size and, most importantly, plant height. According to this indicator, they are conventionally divided into 3 groups: short (15–25 cm), medium tall (26–40 cm) and tall (more than 40 cm).

short

F1 Hawaii Series. Very compact (12–15 cm) leveled plants. The inflorescences are white, blue, blue, purple and violet, flowering very early. The series is suitable for early growing in cassettes.
F1 Neptune Blue. The plants are compact (20–25 cm high), the leaves are large, the inflorescences are blue.
F1 Pearl Blue. Compact, well-branched plants 15–20 cm high and 30 cm wide. The leaves are dark green, the inflorescences are blue. Particularly suitable for early growing and flowering in cassettes.

Medium height
F1 High Tide Series. Powerful semi-compact plants 35–40 cm high and 30 cm wide, branch well in seedlings. Inflorescences blue and white.
F1 Leilani Blue. Powerful, well-branched, semi-compact plants 40–45 cm high and 40 cm wide. The leaves are dark green, the inflorescences are light blue.

Tall
F1 Horizon Blue. Plants are 45–55 cm high (according to some catalogs up to 70 cm), powerful, well branched. The inflorescences are large, purple-blue; Flowering later, abundant. Suitable for growing in pots with a diameter of 10–15 cm, as well as for cutting.
F1 Red Sea. Powerful plants 50–55 cm high with dark green leaves. Flowering later, inflorescences dark purple. Suitable for growing in pots and for cutting.
