Lily - Lilium


Lily is called the lilium flower, a medium-sized or large bulbous, widespread with its many species throughout the northern hemisphere; each bulb, covered with numerous scales, produces a vigorous, erect stem, often brown or dark in color, covered with numerous large ribbon-like leaves, of a bright green color; the stem is produced in spring, and in summer it brings one or more large trombone flowers, of showy color, with large stamens and pistils, very evident, and streaks and spots in a contrasting color. There are dozens of species of lilies, and hundreds more of hybrids; some reach 40-50 cm in height, others reach up to a meter; some produce stolons or rhizomes next to the big bulb, others do not. Some flowers can also be perfumed, and few species are evergreen, although particularly delicate.

How to grow it

As mentioned before there are dozens of species of lily, so different from each other that it was necessary to divide the genus into groups, to better define the cultural characteristics and the different forms of flowers. The lily bulbs more readily available in the nursery are often hybrids, and all have more or less the same cultivation needs: let us place them in a bright place in the garden, even sunny, but fresh and well ventilated. Generally they tend to adapt quite well, so we can plant lilies of the same species in a shady corner, and others in the sun, still obtaining excellent flowering. Many species fear the clayey or very calcareous soils, so before planting them we enrich the soil with universal soil and work thoroughly, so as to make the substratum soft.


During the cold months the plant dries completely, so we can also forget about it; when in spring we see the first thin leaves germinate, followed by the rigid stem, we begin to water the bulbs, avoiding watering when the soil is still wet, and always waiting for it to dry perfectly; we continue to water periodically, avoiding to leave the plant completely dry for excessively long periods of time. Every 10-12 days we add to the water of the watering fertilizer for flowering plants.
After flowering we halve the length of the stems, and continue to cultivate the foliage until the arrival of autumn. Lily plants can be very decorative if planted in groups, even when they are not in bloom.

Lily - Lilium: Pests and diseases

There are many varieties of lilium that can be grown in the garden and may also have rather different characteristics, but all have a certain predisposition to be affected by pests and diseases, such as Erwinia carotovora, a particular bacterium, which causes plants of lilium the rot of the bulb, until the death of the plant. Lilium specimens can also be affected by some viruses that can cause the growth of deformed jets. In this case it is necessary to proceed with the elimination of the affected plants.
