The first days of Indian summer brought night frosts to some parts of our country, killing delicate flowering plants. Warmth still returns during the day, but not all plants recover from the night shock. In such cases, frost-resistant plant species help out, including Sternbergia, which adorns the flower garden in autumn or spring
Rod Sternbergia
The Latin name of the genus, Sternbergia, is pronounced differently in Russian, therefore, if you come across a plant with the name "Sternbergia" in the literature, do not be surprised at their external similarity, since it is one and the same plant. The name immortalized the name of the Czech botanist Kaspar Maria Sternberg, who lived in the late 18th and early 19th centuries.
The genus Sternbergia is not numerous, it has only 8 species of bulbous perennials that can withstand not too severe frosts in the absence of soil moisture. A flower made of yellow petals, with three short stamens and three longer stamens, is wrapped in a bright (usually) veil, which is a modified leaf. Flowers are solitary, briskly located on short peduncles, without trying to break away from the surface of the earth. The rest of the flowers is protected by dark green linear leaves, similar to the stubborn tin soldiers painted with green paint.
Varieties
* Sternbergia grandiflorum (Sternbergia macrantha) - long (up to 30 cm in length) narrow leaves of the plant emerge from the underground bulb in the spring, and in the fall, on low peduncles, golden-yellow large flowers are added to the leaves, reaching a diameter of 10 cm.
* Sternbergia yellow (Sternbergia lutea) is a dwarf species with wide leaves (up to 10 cm wide) and intense yellow flowers, which are the smallest among all species of the genus and appear in the world in autumn. The botanical species is less resistant to frost than the new varieties developed, for example, the narrow-leaved variety, which is more frost-resistant.
* Sternbergia Fischer (Sternbergia fisheriana) - a fifteen-centimeter plant, simultaneously with the appearance of leaves in the spring, gives birth to bright yellow beautiful flowers.
* Sternbergia white (Sternbergia candida) - stands out among its relatives with white petals of flowers that bloom in spring. Sometimes the flowers give off a scent. You don't often see him in nature. The description of the species was made in the second half of the 20th century from specimens growing in southwestern Turkey.
* Sternbergia hibernation (Sternbergia colchiciflora) is a protected rare species that blooms in autumn.
Growing
When summer comes to an end, it is time to plant the Sternbergia bulbs. The bulbs are buried by 10 cm, planting them in open ground, if weather forecasters or folk omens promise a warm winter. Otherwise, it is safer to plant the bulbs in boxes so that they wait out severe frosts in a cool room.
The soil for the bulbs requires loose, light, dry soil during the planting period, since in moist soil the bulbs can die already at plus two degrees. In dry soil, they calmly withstand temperatures up to minus 10 degrees. Watering is required during hot periods
Can grow outdoors, some species tolerate partial shade.
Reproduction
Like all bulbous plants, Sternbergia is easily propagated by baby bulbs, which are separated from the mother bulb in the fall and immediately planted in the ground. With sufficiently well-developed baby bulbs, Sternbergia will delight with flowering as early as next year.
Enemies
In excessively moist soil, the bulbs are attacked by fungi that cause them to rot. In addition, underground living creatures are not averse to feasting on the bulbs of the plant.
On the surface of the earth, the leaves of Sternbergia are attacked. They can be attacked by vile slugs or graceful snails.
