Sub Clover
Subterranean/Sub clover (ssp. subterraneum)

LEURA displays a very prostrate growth habit and produces a low, dense sward. Although relatively soft seeded, it sets sufficient seed to ensure the reliable regeneration.

LEURA is a late-season (147 days to flower) variety, with very low hard seed levels, of the “black-seeded” subterraneum subspecies of sub clover. It is suited to areas with around 700mm annual rainfall, an approximate minimum 8 month growing season.

It is well adapted to moderately acidic (pH CaCI2 4.5-6.5) soils performing best on well-drained, slightly acid soils. LEURA’S formononetin level is very low. LEURA was not selected for red-legged earth mite tolerance. LEURA is suitable for permanent and semi-permanent pastures. Released in 1991, LEURA was a low formononetin alternative to Tallarook.

LEURA’S disease package and winter production was of benefit in some environments over other late varieties at the time of its release. LEURA also made better use of very long seasons than other late varieties Mt Barker and Karridale at the time.
