Lobelia is an extraordinary flower, not only because its color is not very common and somewhat peculiar, but also because it is able to grow without soil - just in water. In addition to blue and blue color, lobelia is found in nature with purple, white and red flowers.

Actually, lobelia belongs to perennials from the bellflower family, but is used as an annual. The homeland of the flower is South Africa, where it usually grows in wet and even rocky places. And some species of this plant have been known as medicinal since ancient times. We also know some varieties of lobelia, which we will try to talk about here. After all, lobelia is one of the most beautiful plants that will be a real decoration for your flower garden.

The most famous varieties of lobelia

  • Lobelia is fiery or shiny - its leaves can be either green or red. This plant reaches a height of 75 cm and came to us from the Mexican lands.
  • Lobelia Dortmann is already an endangered species. It prefers to grow on a sandy clean bottom that is found in coastal areas. The flowers of this variety are painted in a very beautiful blue and white color.
  • Lobelia perennial variety Gherardi grows up to 125 cm in height. Flowers are formed in spike-shaped inflorescences.
  • Lobelia purple is suitable for large plantings, as it forms large groups. It grows well in shallow waters and in wetlands with wet soil, it can be planted around artificial reservoirs and on pond banks.
  • Lobelia sessile is poisonous. It germinates well from seeds and blooms profusely already in the second year of life.
  • Lobelia blue by the middle of summer blooms with spike-shaped blue-violet flowers. Not in great demand among gardeners, probably because it is not very attractive, but very demanding in care.

How does lobelia reproduce?

Like many flowers, lobelia is propagated simply by seed. They are usually sown in a greenhouse in late winter or early spring, when the sun is already beginning to warm up a little. And at the same time, they do not try to embed the seeds in the soil, but simply cover the boxes with seeds with glass or a thick film. Too many seeds do not need to be sown at all. For an ordinary summer cottage, one bag of seeds, or even half of it, is quite enough.

Seedlings begin to appear after 10 or 15 days. By the beginning of planting, the lobelia must be opened. In order to get lush flower bushes, not one plant at a time is planted in the hole, but several at once.

The plant is very fond of sunny areas, so try to find a suitable place for it in advance. This place should be quite humid, because, as you know, lobelia is very fond of water.
If the soil is too fertilized with manure and humus, then there is a possibility that a lush and beautiful flowering will not work.

You need to sow seeds in pre-prepared soil. To do this, you can take ordinary soil from the garden, add sand and humus to it. At the same time, there should be equal parts of sand and earth, but only a tenth of humus. Such a substrate is usually harvested in the fall, even if it freezes a little over the winter, nothing bad will happen to it.

There is one caveat: lobelia seeds need to be sown very rarely, then they will stretch much less during growth.

Seedling care

Small sprouts of lobelia must be watered, but here you must not overdo it and overflow the plant, otherwise they may well get sick with an insidious disease called "black leg" and simply lie down. Water for irrigation should be used slightly warm and preferably settled.

We dive

When small sprouts gradually began to turn into stronger ones, and this happens in about three to four weeks, they need to be cut down, that is, transplanted.

As mentioned above, it is best to plant lobelia in several pieces at once. A special spatula is needed for a dive, and if it is not there, then a sharp stick will do. She will need to pick up 4-7 plants and plant them in very small containers - cups.

Further care

When the plants in the cups have reached the required height (about 3 cm), you need to pinch them. This is done in order for the bushes to be lush and beautiful in the future.

And planting seedlings directly into the ground should be done when the threat of frost has passed. And this will be in late May - early June. Although, it must be admitted that this plant will still be able to tolerate small night frosts up to -1 degrees.

Lobelia, with proper care, will begin to bloom at the end of the first summer month, and continues to delight with its beauty all summer long. True, by August flowering is already slowing down a little, gradually fading away.

At this time, you can just loosen the soil, water the plant well, and it will begin to bloom profusely again.

But by the beginning of October, however, flowering stops altogether, because autumn frosts come.

If you want lobelia to delight you with its flowers all year round, then carefully dig up the plant and transplant it into an ordinary flower pot. Bring it home and enjoy blooming even in cold winters.
