- Description
-
Ranunculus is a genus of perennial or annual herbs in the Ranunculaceae family. The leaves are usually alternate and palmately lobed or divided. While the thimble-like, April-blooming, often shiny flowers are most commonly yellow, cultivars have been bred bearing many other colors such as orange, pink, red, and white. The flowers give way to a head of small, dry achenes; because of this, some species can be a bit weedy in disturbed areas. However, they are great pollinator plants and serve as food for hummingbirds. Consider using them for beds, borders, rock gardens, and fresh cut flowers.
These plants do best in full to PM sun. When planting, cover the tuberous roots 3 in. (7.5 cm) in soil and space 3-6 in. (8-15 cm) apart. Soak the tubers for 1 hour before planting or water well once planted. The foliage tends to die down in the summer.
