There are many species in the plant genus Cynoglossum (/ˌsɪnoʊˈɡlɒsəm, ˌsaɪ-, -nə-/). They are coarse-appearing, small-flowered plants of the family Boraginaceae. Cynoglossum officinale, the common hound's-tongue, is a native of Asia, Africa, and Europe. It has been introduced into North America, and it is considered to be a troublesome weed because its burs stick to the wool of sheep and to other animals. Ingestion of this plant can also lead to photosensitivity in grazing animals. Cynoglossum blue are also known as Forget-me-nots. "Cynoglossom Grande" is native to California.
