Riverina

Sub Clover
Subterranean/Sub clover (ssp. yanninicum)

Riverina is mid season (119 days to flower) variety, it belongs to the water logging tolerant “white-seeded” subspecies yanninicum of sub clover, and is derived from the same cross as Gosse, (Meteora/Trikkala) and was bred by Dr J S Gladstones from the University of WA.

Riverina can be sown across a wide range of soil types in the 450mm plus rainfall zones with a pH of 4.5 and above.
