About

Also known as 'alfalfa'or 'purple medic' this herbaceous perennial legume with a deep tap-root and clover-like green foliage produces small purple flowers in the summer followed by flat pea-like fruits. Used in many countries as animal food or as a green crop as it improves nutrient levels in the soil and also soil quality by reducing compaction, also reducing the need for synthetic fertilisers.
