Lupin is a decorative plant from the pea family, growing as a powerful bush with a height from 80 cm to 1.5 m. Lupin flowers are diverse: blue-violet, blue, cream, white, red, and purple, creating a bright contrast and attracting the gaze of gardeners. The leaves are palmate, long, and decorative, while the rhizomes are deep – up to 2 m, which ensures the plant's stability even in weakly fertile soils.
For successful lupin cultivation, sunny locations and weakly acidic or weakly alkaline soil are required. Seeds are sown from late April to early May, and after flowering is completed – in the autumn period. Regular feeding with non-nitrogenous fertilizer with a high potassium and phosphorus content promotes rapid growth and abundant flowering. After 5–6 years, the plant requires division to maintain its decorative properties.
Lupin is a frost-hardy plant that does not require winter covering. During the cold season, it is pruned to a height of 20 cm and the root collar is covered, protecting it from harsh conditions. This plant combines well with delphiniums, irises, chamomiles, and heucheras, creating harmonious compositions in various garden styles.
