Bau-Sin is a broad-leaved Heading mustard with thick and broad stalks. This mild, sweet Indian mustard possesses glossy, golden green leaves with a trace of red veining. The leaves are fine for salads, and are high in pro-vitamin A and C. Plants mature to a beautifully folded heart prior to bolting and may even form a head in cold weather. Stems of bolting plants are sweet, crisp and tender, although it may become bitter if overgrown. Seeds are sown in late summer for harvest in late fall and early winter. Bau-Sin is very popular in Taiwan and southern China.
