Lupinus albus, commonly known as White Lupin, is an annual herb native to the Mediterranean region, particularly found in meadows, pastures, and grassy slopes with sandy and acidic soils. It typically grows to a height of 12 to 47 inches (30 to 120 centimeters). White Lupin is characterized by its palmate leaves and erect, showy flower spikes that bloom in late spring to summer, displaying a range of colors including blue, violet, pink, or white. The flowers are followed by hairy seed pods that contain the lupin seeds, which are notable for their culinary use after proper preparation to remove alkaloids.

White Lupin is valued for its nitrogen-fixing abilities, which can improve soil fertility, making it beneficial in agricultural settings as a green manure crop. In gardens, it is often grown for its attractive flowers and as a cover crop. It requires well-drained, moderately fertile soil and thrives in full sun to part shade. While generally easy to grow, it can be susceptible to fungal diseases and aphid infestations. White Lupin is potentially invasive in some regions outside its native range due to its prolific seed production and adaptability to various environments. Gardeners should consult local guidelines before planting to prevent unintended spread.CC BY-SA 4.0
