This annual winter legume is characterized by hollow stems and non-hairy, arrow-shaped leaves with a V white water mark. It has cylindrical shape flower head that is usually white and turn pink or purple as they mature. One peculiar characteristic is that maturity occurs from the basal part of the plant to the top.
Blackhawk - NEW TO DLF - Blackhawk arrowleaf clover was developed by Dr. G. R. Smith with Texas A&M Agrilife Research in Overton, Texas. Advanced dark seeded selections from Yucchi, Amclo, and Meechee were subjected to six cycles of selection for tolerance to Phythium ultimum and bean yellow mosaic virus (BYMV). Dark seed coats have been associated with resistance to Pythium and other soil-borne pathogen. Blackhawk seed is 95% black with a light variation in color degree and is highly resistant to Pythium ultimum. Blackhawk is also resistant to BYMV - induced lethal wilt, and shows resistance to other components of BYMV. Blackhawk is slightly earlier in maturity, but maintains its high forage production through multiple grazing's.
