Ranunculus are part of the buttercup family of plants. The brightly coloured flowers are about 20 cm tall with layers of delicate crepe petals on green stems. They will flower in March from autumn-planted corms, or June and July from spring ones, each lasting about six weeks. The corms look like little claws, they will remain dormant for a long time until you are ready to plant them. You get fifteen corms with this order.
