Watercress     豆瓣菜(水芹)     $3.50      100 Seeds 
 
Crisp and wonderful in salad and sandwiches, this member of the brassica family has been eaten and cultivated for over three millennia. Like its mustard cousins it has crisp leaves with a tangy flavor. Its dark green, small crisp leaves and young stems have a peppery flavor. It is recommended to harvest when young as watercress becomes bitter when it starts to flower. High in vitamins A and C. Grows in USDA zones 1-5 as an annual and in USDA zones 6-9 as a perennial. Best eaten soon after harvest. 50-60 days.
