About

The white lupin is an annual herbaceous plant native to the eastern Mediterranean region. In a food forest, it stands out for its fundamental role as a nitrogen fixer, functioning as an excellent winter green manure. Additionally, it features a strong root system that helps to decompact the soil and attractive flowers for pollinators.

It can be planted now — September is one of the best months.
