About salsify
Salsify is a biennial, so it spends its first year building leaves and a thick root and flowers in its second year. Its grass-like leaves form a rosette at the base, and the root can be eaten as a vegetable with an oyster-like flavor. Plants grow about 1.6 to 3.3 feet (0.5 to 1 m) tall, with purple-pink, dandelion-like flowers about 1 to 2 inches (3 to 5 cm) across.
