Lupine (Lupinus) – a perennial decorative plant of the legume family, known for its drought and frost resistance. The height of an adult plant is usually between 60 and 90 cm, and the flowers are small, bell-shaped, white-yellow or purple, gathered in spike-like inflorescences. Blooming occurs in spring (April-May) and sometimes repeats in August; the plant can withstand long periods without watering and even winters down to -29°C if covered with conifer branches.
For successful cultivation, lupine requires a sunny or semi-shaded area with fertile, well-drained soil. It does not tolerate waterlogging, so good water drainage is essential, and acidic soils should be avoided – if necessary, they can be neutralized with lime or wood ash. Seeds germinate at 15-16°C; in the growth phase up to 4-6 leaves, the plant is sensitive to low temperatures, development slows below +10°C.
Care for lupine is simple: regular watering during active growth, soil loosening, and weed removal. If necessary, it can be fed with nitrogen fertilizers, although the plant itself fixes nitrogen thanks to symbiosis with bacteria in the root system. After 4-5 years of flowering, it is recommended to transplant a new bush, as the central part of the plant gradually dies and side rosettes form. These rosettes can be left without transplanting, but they should be pruned to prevent the root stem from rising.
Lupine combines easily with other decorative plants – peonies, daisies, irises, creating harmonious compositions in gardens and parks. Thanks to its beauty, ease of care, and resistance to adverse conditions, it has become a popular choice for city flower beds and landscape greening.
