Adonis for the Garden

Adonis-amurensisNative to Europe, Africa and Asia, Adonis is a genus in the buttercup family, Ranunculaceae, that also includes anemone, delphinium, and hellebore. There are about twenty species but only a few that are considered garden-worthy. The erect plants are herbaceous perennials or annuals and have finely dissected, light green leaves, and flowers with white, yellow, orange or red petals. The perennials need about six weeks of temperatures below 40 F for the rhizomes to break dormancy in spring and go dormant again by mid-summer. Plants are suitable for rock gardens or front of the border, and should be massed for a good floral display. Not fussy about soil, plants need full sun with afternoon shade in the South. Slugs can be a problem. Propagate by seed (annuals and perennials) or division (perennials) in spring after the foliage has died down.
