The common names for Adonis (which can be either a hardy annual or perennial) include Pheasant's eye, False Hellebore, Sweet Vernal and Red Morocco.
The annuals typically flower in the summer, whereas the perennials flower in the early spring.
Adonis genus members are usually low growing plants, though some species can reach 20 inches (50 cm) in height.
Adonis annuals and perennials bear yellow, red, or white flowers resembling those of buttercups.
As a consequence of the perennials being very early flowering, they are great to use in the garden to bring some much needed colour following the winter.
Adonis plants can look wonderful when grown against pathways or in a rockery.
