Lobelia of the "Emperor Willy" variety (variant of the name - William) - a plant of the bellflower family - is valued by gardeners for its luxurious flowering, which lasts from mid-June to the last days of September.

Unpretentious and perfectly combined with other flowers, it is used to decorate flower beds, ridges, borders, alpine slides and hanging planters. The features of its cultivation will be discussed in our article.

Botanical description and photo

Lobelia "Emperor Willy" - a perennial flower culture, which in the climatic conditions of the Russian Federation is grown as an annual. Endowed with high decorative properties, it forms compact spherical bushes, the height of which does not exceed 15 cm.

Thin stems, densely covered with many small lanceolate leaves, arranged alternately, strongly branching at the base. Due to the large number of dense dark green leaves, the bushes do not lose their decorative effect even after flowering.

Quite large (up to 2 cm in diameter) bright blue double-lipped flowers, endowed with short pedicels, sit one by one in the axils of the leaf plates, densely covering the branched stems. The fluffier the bush, the more flowers it has.

Distinctive features

Lobelia "Emperor Willy" has a number of advantages that distinguish it favorably from a number of other varieties. It is characterized by:

  • Continuous (June to September) profuse flowering.
  • High resistance to insect pests, as well as to viral and fungal diseases.
  • The ability to grow well and bloom luxuriantly even on lean soils.
  • Good shade tolerance. Bushes grow well in partial shade, under shrubs and trees.
  • The ability to give amicable shoots and a faster rate of development of seedlings than lobelia of other varieties.
  • High variability of application in landscape design (it is used in borders, ridges, flower beds, alpine slides and when decorating verandas and balconies).

A few disadvantages of the variety are presented:

  • the difficulty of picking due to the fragility and diminutiveness of the seedlings;
  • exactingness to the ambient temperature and humidity level.

Planting: where and how to plant?

Russian florists grow lobelia seedlings... 7-10 days before transplanting into open ground, the seedlings are hardened: thanks to this procedure, it experiences less stress and takes root better in a new place.

Seedlings should be hardened after the ambient temperature is set at 13-15 degrees Celsius:

  1. For the first two or three days, boxes with seedlings are taken out on a glazed balcony for several hours or kept under an open window.
  2. After that, hardening continues in the open air, for the first time exposing the seedlings to the shade for 30 minutes. Every day, the time spent by seedlings on the street is gradually increased and gradually taken out of the shade.

You can plant hardened seedlings in balcony boxes or open-air flower beds in mid-May.

Rules for moving into open ground

  1. Dig up the soil in the flower bed; if necessary, a certain amount of peat, river sand and granular mineral fertilizers are introduced into it.
  2. Landing holes are made 15-20 cm apart from each other.
  3. The soil in the holes is moistened abundantly.
  4. In each hole, carefully, trying not to damage the earthen lump, place a bush consisting of 6-7 seedlings. The soil around it is slightly compacted.

Important! To make a continuous dense clearing, no more than 10-15 cm is left between the bushes; if you plan to create a mixed flower arrangement, this distance is increased to 20-25 cm.

Lighting and location

Lobelia "Emperor Willy" equally good blooms both in sunny (with the maximum amount of natural light) and in semi-shaded areasprotected from the penetration of cold gusty winds.

Soil requirements

  • Lobelia grows well on loose, moist, breathable substrates. All these requirements are met by ready-made soil, which can be bought in a specialized store.
  • If desired, the soil mixture can be made independently, taking one part of garden soil and mineral fertilizers of prolonged (long-term) action and 1.5 parts of coarse river sand.
  • The easiest recipe for a lobelia potting soil mix is ​​to mix equal amounts of regular garden soil and vermiculite. Vermiculite is capable of: preserving the looseness of the soil, protecting it from sudden temperature changes in the environment, neutralizing the high acidity of the soil and ensuring the optimal level of its moisture.
  • Lobelia does not like acidic soils. The situation can be corrected by introducing dolomite flour or wood ash into the soil.
  • The substrate intended for growing seedlings is disinfected by steaming it in a water bath or calcining it in an oven just before the seed sowing procedure. Freezing of the soil gives a good effect (it is enough to hold it on an unheated balcony since autumn).

Attention! In order to achieve abundant flowering of lobelia, oversaturation of the soil with organic matter (humus or manure) should be avoided, since in this case all the plant's forces will go to building up green mass. Lobelia will bush beautifully, its leaves will turn bright green, but flowering will be rather scarce.

Features of care and reproduction

Lobelia "Emperor Willy" is most often propagated by seeds: by growing seedlings either at home or in a greenhouse.

At home

Seed germination of this variety is 85%.

Therefore, even from a small amount of them, you can get many healthy seedlings that are resistant to pests and diseases (subject to proper care).

Planting lobelia seeds is best done at the end of February. - early March: seedlings grown in natural light are characterized by compactness, high viability and resistance to the fungal infection called "black leg".

Step-by-step instructions for growing from seeds

  1. A day before sowing, the planting containers are filled with prepared soil mixture, it is slightly compacted and, after watering abundantly, it is left for 24 hours. It is best to use wide, but shallow trays with drainage holes as a planting container. It is recommended to add a fungicidal preparation to the water intended for the primary irrigation of the soil.
  2. The surface of the substrate is carefully leveled.
  3. After sprinkling the seeds on a sheet of paper, previously bent in half, and gently tapping it with your finger, distribute them evenly over the soil surface.
  4. The sown seeds are not sprinkled with a substrate, but only sprayed with water at room temperature from a spray bottle.
  5. Covering the container with glass or a piece of polyethylene, place it in a warm (with an air temperature of 23-25 ​​degrees), well-lit place. A week later, dense friendly shoots will appear in the greenhouse.

Basic Rules

  1. The greenhouse with crops must be ventilated 2 times a day (morning and evening), removing the film or glass from it and always wiping off condensation from their surface. The airing time is gradually increased: from 10 to 40 minutes per day.
  2. A month after sowing the seeds, the shelter is finally removed, and the boxes with seedlings are moved to a cooler, but lighter room with an air temperature not exceeding 18 degrees.
  3. After the appearance of 3-4 leaves, the seedlings dive into separate cups, placing them in piles, 6-7 pieces in each, doing this with the help of a special small spatula.
  4. The stems of seedlings that have reached three centimeters in height are pinched: this manipulation contributes to the formation of dense bushes. The pinching procedure is repeated several times (the interval between them is 15-20 days).
  5. Seedlings are transplanted into open ground at the end of May - early June, after the final establishment of heat.

In the greenhouse

In greenhouses, seeds are sown in mid-February - early March.:

  1. The soil mixture, consisting of coarse sand, garden soil and leaf humus, is harvested in the fall and frozen in order to do without disinfecting it before sowing.
  2. Having evenly distributed the seeds over the surface of the soil, spray them from a spray bottle, after which the planting containers are covered with glass and wait for the emergence of seedlings (this happens 2 weeks later).
  3. The grown seedlings dive with the help of a small spatula, which helps to grab the roots together with the earthy clod. To form a lush bush, 5-6 seedlings are planted at once in each planting hole during a pick.
  4. Seedlings, the height of which has reached three centimeters, are pinched to stimulate tillering.
  5. In the last days of May, young plants are transplanted into open ground: they can withstand frosts down to -1, they can do without shelter.


Lobelia of the "Emperor Willy" variety, which is a perennial plant, is sometimes propagated by cuttings. To do this, having chosen an adult plant with strong, well-developed stems, in the last days of October - early November, by transshipment, they are transplanted into a separate pot, bring it into the house and carefully look after it throughout the winter, providing:

  • moderate watering;
  • weekly mineral dressing;
  • bright lighting;
  • the air temperature is not lower than 18-20 degrees.

In March, they start cutting cuttings, acting in accordance with the algorithm:

  1. Healthy twigs from 8 to 9 cm long are cut from the bush (the cuts should be oblique).
  2. Cuttings are immersed in a solution of a root formation stimulator for 2-3 hours (most often the drug "Kornevin" is used).
  3. Treated cuttings are planted in pots filled with a substrate made from coconut fibers, river sand and fertile soil, taken in equal proportions (there should be a drainage layer at the bottom of the pots).

    Important! Before planting the cuttings, the soil mixture must be sieved: thanks to this manipulation, it acquires the necessary lightness and friability.

  4. Pots with cuttings are placed under glass or foil. The rooting process takes at least a month.
  5. 6 weeks after planting, the rooted cuttings are transplanted to the place of permanent growth.


In order for the Emperor Willy lobelia to actively develop and delight the owner with lush flowering, care should be taken to take into account the following requirements:

  • Compliance with temperature conditions... Germination of seeds should take place at a temperature of 22 to 24 degrees. During the growth of seedlings, the air temperature should be 19-20 degrees. Planting seedlings in open ground is carried out at an ambient temperature of at least 15 degrees.
  • Watering rules... When growing seedlings, seedlings are watered either with a syringe, under the root, or in a tray. The use of a spray bottle is also permitted. When watering adult plants, water is also poured strictly under the root, doing this as the substrate dries up - no more than 3-4 times a week.
  • Lighting requirements... The light-loving Emperor Willy lobelia, grown as a houseplant, is best placed on windows facing west or east. In direct sunlight, it is better to shade the lobelia pot slightly with a tulle curtain.
  • Top dressing rules... To fertilize lobelia of this variety, two dressings are enough:
    1. The first of them, consisting in the introduction of organic fertilizers, contributing to the active development of shoots and the root system, is performed 2 weeks after sowing the seeds.
    2. The second top dressing - with any fertilizer for abundantly flowering plants - is carried out in early June, before flowering begins.

    Attention! In the chemical formula of the applied fertilizers, the presence of phosphorus, potassium and nitrogen is mandatory.

  • Pruning procedure... In August, after the first wave of flowering, lobelia for some time loses its decorative effect due to the exposure of the stems. At this moment, the exposed shoots are cut off, leaving no more than 5 cm from the base of the bushes. This treatment stimulates the second wave of exuberant flowering, which comes very soon.

From all of the above, only one conclusion follows: growing lobelia is a troublesome business, but very exciting, and even a beginner grower can do it.
