Description

Amsinckia, or Fiddleneck, is a genus of bristly, flowering annual plants in the Boraginaceae family. The common name is derived from the gray-green flowering stems laden with goldenrod yellow blooms that bend and curl like the end of a fiddle. The genus contains about a dozen different species that are often difficult to distinguish from one another because their ranges overlap and the species often hybridise naturally. 

Most species in the genus have an erect stem, whose height varies from 8 to 48 inches and most are found at relatively low altitude.

Insects, Diseases, and Other Plant Problems: 

No known insect pests or diseases. However, contact with the plant's sharp hairs can cause contact dermatitis. The seeds and leaves of fiddlenecks have pyrrolizidine alkaloids that are poisonous to livestock including horses.
