Adonis–commonly called pheasant’s eye–is a genus of perennial and annual brightly colored flowers. Perennial Adonis species bear bright yellow flowers; annual species bear scarlet red flowers. Adonis blooms in late winter and early spring and then goes dormant in the summer.

Adonis flowers are similar to daisies and anemones; their bowl-shaped flowers are composed of as few as 5 petals (annual species) and as many as 30 petals (perennial species). The 2-inch-wide flowers appear above finely cut, fern-like leaves.

Adonis form large mounds of color. Use them at the front of borders or as edging. They will grow in full sun or partial shade, but cannot stand extreme heat. They thrive best where summer nighttime temperatures drop below 65°F (18°C).

Adonis is a genus of about 20 species of annuals and perennials from Europe and Asia, mainly from alpine habitats.
