This genus includes some species of vibrant bulbous plants originating in Europe, Asia and Africa. The bulbs produce numerous long and narrow leaves, arranged in a narrow upright rosette; from May to July from the rosette of leaves grow some 10-15 cm tall stems that carry clusters of 5-6 star-like flowers, of violet, blue, blue or white color depending on the species.
Some species produce small flowers gathered in long panicles. These bulbous plants are widely used in flowerbeds and borders, and are also very suitable for rock gardens.
There are several species of Scilla that are cultivated for ornamental purposes, such as Scilla bifolia, Scilla litardierei, Scilla mischtschenkoana, Scilla peruviana and finally Scilla Siberica.
The Scilla siberica is particularly suitable for places with cold winters, to which it resists without problems. This variety usually reaches 20-30 centimeters in height and produces inflorescences with bright blue flowers that are most often asymmetrical.
The scilla prefer sunny positions, even if they develop without problems in areas with few hours of sunshine per day; they do not fear the cold, since in winter they are in vegetative rest, therefore the bulbs can easily be left underground, where they naturalize without problems, producing numerous new bulbs over time.
The flowering period of these plants is spring and in particular the beginning of spring. In mountain areas or in areas with low temperatures flowering can be delayed and take place in late spring.
From March to August water abundantly, especially during flowering. In the vegetative period, provide fertilizer for bulbous plants dissolved in the water of the watering every 10-15 days. In summer and winter, it can easily withstand periods of drought.
The best areas to place the scilla bulbs are the cooler ones and by choosing areas with these characteristics the watering can be reduced.
These bulbous plants prefer loose, well-drained soils rich in organic matter; when planting it is good to work the soil well, mixing sand and mature organic fertilizer.
In very hot areas after flowering it is good to dig up the Scilla plants and bring them to cooler areas for a period, in order to stimulate the bulbs to push back once past this period of low temperatures.
In spring it is possible to sow the small seeds that the seedlings produce in large quantities, in fact they usually tend to self-seed. In autumn it is possible to remove the bulbs produced profusely from the bulbs buried for some years. The division of the bulbs is a delicate operation to be carried out precisely. We will have to proceed with the cutting of the bulbs that have spread and with the division, with the help of a sharp blade scissors.
False hyacinth, Siberian Scilla - Scilla siberica: Pests and diseases
The scilla plants do not suffer from particular diseases and do not have particular pests that attack them but attention must be paid to the root rot of the bulbs. When the soil remains moist for too long there may be a strong danger of developing root rot, mold and fungus that can affect the health of our bulbous plants.
