Bushes can be globular, compact or creeping, reach a height of 10 to 40 cm, depending on the type of plant. Flowering shoots of the first, second and third orders develop.
The stems secrete milky juice. Shoots that touch the ground are capable of rooting.
The leaves on the stem are alternately arranged in a spiral, have an oval, pointed shape, notched-toothed along the edge, 3-6 cm long and 1-1.5 cm wide, light or dark green, may be with a lilac tint.

The upper lip consists of two fused narrow petals, the lower one consists of three wider ones. Flowers are located mainly at the top of the shoot and emerge from the axils of the leaves.
The flowers have a short peduncle and a deep five-lobed calyx. The flower has five stamens and one pistil, which is a filamentous column with a bipartite stigma. Fringed anthers are at the apex, the ovary is inferior.
The color of flowers, depending on the species, can be light blue, dark blue, violet, purple and white.
Blooms from June to October, the seeds ripen in late August to early September.
The fruit is a two-celled capsule with a large number of seeds. Seeds are small, smooth, shiny, have an elliptical shape (length 0.4-0.6 mm and width up to 0.4 mm). Seed with a straight embryo. The color can be light or dark brown, for flowers with white petals - cream.
Lobelia erinus is considered to be home to the Cape region of South Africa, where it grows among bushes in humid, rocky places. Flowers are induced and are now widely distributed throughout the world, but most of all lobelia erinus is grown in temperate and subtropical zones. In Russia, it is often found in parks and gardens.
Lobelia erinus is named after the famous Dutch botanist and physician of the English king James I Matthias de Lobel (1538-1616). For some time he headed the Royal Botanical Garden.

Description of appearance
Grows in the form of a small dense bush that is prone to branching. Florists distinguish five types of garden lobelia, depending on the shape of the bush and crown:
- Spreading... Height up to 15 cm. Shoots no more than 30 cm.
- Compact... The bush has a spherical shape and reaches a height of up to 20 cm.
- Dwarf... Grows up to 12 cm.
- Hanging or ampelous... Shoots go down and grow up to 40 cm.
- Erect... The stems grow up to 20 cm.
During flowering, the plant is covered with small flowers of various colors, but most of them are colder shades. Due to the large number of flowers, the leaves are practically invisible, because a beautiful bud is blooming in each axil of the leaf.
Varieties: distinctive features and photos
The bush reaches a height of 15 cm. The crown is neat, with densely planted flowers and leaves. The leaves are bright green with a bronze tint. Leaves grow alternately. Branched stems.

The buds are distinguished by a rich blue color, small in size up to 2 cm... The flowers completely cover the stems, and therefore the leaves are practically invisible. This variety grows in full sun. Usually propagated by seeds. Seedlings take root well in open ground and in pots.
The bush is compact and undersized, reaches a height of 13-16 cm. The crown is round and lush. The stems branch from the base. The leaves are dark green with a golden tint, small and elongated. The flower petals are blue, purple, cornflower blue and reach up to 3 cm in diameter. It grows well in loose and fertile soil. Place of cultivation - flower beds, flower beds, borders.

The disadvantage of lobelia erinus is that it does not tolerate high frosts, so the bush must be dug out for the winter.
Where and how to plant: rules and tips
Lighting and location
Lobelia Erinus needs a place well lit by the sunbut direct sunlight is undesirable. The eastern and western areas of the house are the best places for planting. If water stagnates in these places, then drainage is necessary.
The soil should be loose and moderately fertile; garden cultivated soil is well suited for the plant. The soil does not need to be overfed with mineral fertilizers and organic matter, because the plant will grow foliage and will not bloom.
For sowing seeds, it is necessary to use sand mixtures, which include sand, garden soil and humus in equal parts.
Most often, erinos lobelia is propagated using seeds, less often by cuttings.
Seed propagation takes a long period of time, but it is a reliable way to get quality seedlings. It takes root well and is resistant to diseases and pests.
- Seeds are harvested in early September from a healthy bush or purchased in flower shops. They have a long shelf life (up to 4-5 years).
- Sowing seeds in the ground is done at the end of February or at the beginning of March. Since they are small, for an even distribution, you can mix them with sand in a ratio of 1: 5 or first pour snow about 1 cm thick, and then you can sow the seeds.
Attention! When sowing, the seeds are not embedded in the soil, but slightly pressed against it.
- Moisten the crop with a fine spray and cover with glass.
- You need to air it every day for 20-30 minutes, and bring the time to 2 hours, remove condensation from the surface of the film.
- Shoots appear after 10 days. Water only with a sprayer and when the sprouts grow up to 3 cm, you need to remove the film and cut off the top. Pruning is carried out 2-3 times every 3-4 weeks for good tillering of the flower.
- After one month, it is necessary to pick and transplant plants. They must be transplanted into separate pots by 5 pieces. The transplant is carried out using a special spatula.
- Two months later, in May, you need to transplant it into open ground.
- The distance between the planting holes should be about 20 cm, their depth is 3 cm more than the earthen coma of the plant. Plant 2-3 seedlings in one hole for flowering density. The substrate must be moistened and tamped.
Water for irrigation needs warm and settled water.
Reproduction by cuttings is not a difficult process; for this, a healthy bush is used, which was dug out in the fall for the winter. Cuttings are carried out at the end of February or at the beginning of March..
- It is necessary to cut diagonally cuttings 6-10 cm long and treat with any growth stimulant.
- Plant in prepared moist soil and cover with glass.
- Rooting takes place after about a month.
- Use top dressing in the form of a liquid mineral fertilizer.
- Then, two months after planting, transplant it into open ground.
At the end of the season, mature plants can be dug up and transplanted into a pot.... At room temperature and sufficient light, lobelia erinus continues to bloom even in winter.
Features of care and reproduction
- The optimum temperature for lobelia erinus is 20-24 degrees.
- Watering should be regular. Water as the earth dries up. If the water stagnates, then a drainage system must be installed. It is recommended to water several times a week.
- Pruning and clothespin. For re-flowering, the plant at the end of July must be cut off the tops of the shoots with peduncles by 5-7 cm.
- It is necessary to carry out top dressing 2-3 times per season. Frequent feeding with nitrogen-containing fertilizers and organic matter are contraindicated, since they accelerate the growth of green mass, but at the same time reduce the formation of buds.
- Seed collection is carried out strictly from a healthy plant.
Lobelia Erinus is not whimsical at all and can be grown by any amateur florist. Breeding her at home, you will never regret it. And the flower will thank you with abundant flowering before the onset of the cold weather.
