[edit] Botany

The leaves, which may grow up to eight inches, are lobed and covered in fine hairs, forming a low-lying rosette around a central taproot. Multiple forked stems carry bright yellow flower heads, and when mature these form seeds attached to windborne "parachutes". All parts of the plant exude a milky sap when cut.

Hypochaeris species are used as food plants by the larvae of some Lepidoptera species including The Shark.

[edit] Etymology and differences to dandelions

Catsear is derived from the words cat's ear, and refers to the shape and fine-hair on the leaves resembling that of the ear of a cat.

The plant is also known as false dandelion, as it is commonly mistaken for true dandelions. Both plants carry similar flowers which form into windborne seeds. However, catsear flowering stems are forked and solid, whereas dandelions possess unforked stems that are hollow. Both plants have a rosette of leaves and a central taproot. The leaves of dandelions are jagged in appearance, whereas those of catsear are more lobe-shaped and hairy. Both plants have similar uses.

[edit] Culinary uses

All parts of the catsear plant are edible; however, the leaves and roots are those most often harvested. The leaves are bland in taste but can be eaten raw in salads, steamed, or in stir-fries. Older leaves can become tough and fibrous, but younger leaves make for good eating. Some bitterness in the leaves may be apparent but is rare.

The root can be roasted and ground to form a coffee substitute.

[edit] Toxicity

Catsear is considered a noxious weed for livestock and horses. Ingestion of large amounts of catsear can cause a neurological disorder in horses called stringhalt. Stringhalt causes involuntary twitching in the rear legs of the animal and other problems. The symptoms of catsear exposure may clear out of the system in a few years once grazing on the plant has been eliminated from the horse's diet.
