Berseem Clover Green Manure Seeds
Botanical Name: Trifolium alexandrinum
Fast-growing winter cover crop for improving soil health.
Excellent nitrogen-fixing green manure for Australian gardens and farms.
Produces abundant biomass to build fertile, living soils.
Berseem Clover (Trifolium alexandrinum) is a vigorous annual legume widely grown as a green manure, cover crop and high-quality forage throughout Australia. Valued for its rapid establishment and impressive biomass production, Berseem Clover captures atmospheric nitrogen through beneficial root bacteria, helping to improve soil fertility naturally while reducing the need for synthetic fertilisers.
Ideal for vegetable gardens, orchards, vineyards, market gardens and broadacre cropping, Berseem Clover forms a dense canopy that suppresses weeds, protects the soil from erosion and adds valuable organic matter when incorporated back into the soil. Its attractive white flower heads are also highly beneficial for bees and other pollinating insects during spring.
