Sweet Clover (Melilotus spp.)

Cool Season

Sweet clover has two main types. Yellow Blossom is a biennial and White is an annual. Both are upright plants with decent drought tolerance once established. Salinity tolerance is quite good. Sweet clover is renown for improving marginal soil by increasing the organic matter quickly. Plants are tolerant of heat and shading. Tap root is fairly aggressive and is able to loosen hard soils. Yellow blossom has very good winter hardiness.
