Also acidic soils are not appropriate for the cultivation of common sainfoin. To reach high levels of condensed tannins common sainfoin should be sown in pure culture. She was named after the racehorse Sainfoin, the winner of the 1890 Derby. He never challenged the leaders but kept on to finish fourth behind winner Sainfoin. The new information concerned new crops such as woad, clover, sainfoin, lucerne, etc. The leaves of common sainfoin contain high levels of condensed tannins. Trefoil and sainfoin are sown to improve pasture land. In the finishing straight Sainfoin pulled clear and was followed by Surefoot and Amphion. Hayraddin led Sainfoin and Amphion away from the start. In May 1890, he bought a racehorse called Sainfoin. HMS "Sainfoin" sailed to Greenock to embark Royal Marines from 553 flotilla. The larvae feed on "Astragalus" species and possibly sainfoin. Also the yields of common sainfoin are significantly lower than those of alfalfa and clover. Mated in 1899 with Sainfoin, Roquebrune produced Rock Sand, her first foal. Sainfoin, who had since won the Derby, was the even money favourite.
