Winter Aconite Eranthis Hyemalis Wildflower Hardy Perennial

It is a tuberous-rooted herbaceous perennial growing to 15 cm (6 in), with large (2–3 cm (1–1 in)), yellow, cup-shaped flowers held above a collar of 3 leaf-like bracts, appearing in late winter and early spring. The six sepals are bright yellow and petaloid, and the petals are in the form of tubular nectaries. There are numerous stamens and usually six unfused carpels.

As a spring ephemeral plant, its life cycle exploits the deciduous woodland canopy, flowering at the time of maximum sunlight reaching the forest floor, then completely dying back to its underground tuber after flowering.

The plant is valued in cultivation as one of the earliest of all flowers to appear. It has gained the Royal Horticultural Society's Award of Garden Merit.

All parts of the plant are poisonous when consumed by humans and other mammals.
