Subterranean clovers offer a range of low-growing, self-reseeding legumes with high nitrogen contribution and excellent weed suppression. They grow close to the ground, piling up the biomass in a compact layer.
Subclover cultivars are described by their days to maturity, which can vary from 85 days to 130 days. Denser and less viny than hairy vetch, it persists longer as a weed-controlling mulch.
Subclovers thrive in Mediterranean climates of mild, moist winters and dry summers.
