How to grow Lupinus polyphyllus:

It is easy to grow and does well in moist, cool locations. Grow it in the sun where it flowers profusely. However, in hot climates afternoon shade will help. They prefer cool summers but plenty of light. Good air circulation will prevent powdery mildew. Plant it in organically rich, slightly acidic, evenly moist soil. Lupines have a nitrogen-fixing capability and can help improve soil conditions. Watch out for slugs, snails, aphids, and powdery mildew.

Lupinus polyphyllus hybrids come in a range of colors from white, yellow, deep blue and purple, pink and violet, and red. Russell hybrids are probably the best-known. George Russel, the English gardener, cultivated the Russell hybrids.

You can start Lupinus polyphyllus from seeds, they are a bit fussy about their soil specially for the second year. Propagate from side shoot cuttings. Lupinus polyphyllus is considered invasive in New Zealand, Sweden, Switzerland, Norway, Czech Republic, Finland, Lithuania, Ukraine, and Argentina.

About Online Flower Garden & Dino

I am a flower enthusiast and a gardener at heart. Ever since childhood I loved reading about plants and started gardening at an early age. First by helping my father in the garden and later managing a large garden myself in my teen years. I planted and cared for a large number of plants, flowers, and trees both outdoors and in a greenhouse. To this day I enjoy visiting gardens and parks and learning about new and old specimens and varieties of plants.
