A small plant with short, spike-like, terminal clusters of pale lavender flowers on a hairy stem and its branches.
There are several species of eyebright, native to the colder regions. They are partly parasitic on the roots of other plants. The common name refers to the fact that the plants were at one time used to treat eye diseases and improve vision. The genus name, from the Greek word for cheerfulness, may allude to the same properties.
