Winter Aconite (Eranthis) is a Winter flowering tuber.
It flowers from January to March.

The Winter Aconite has a yellow buttercup shaped flower and is surrounded by a collar of ruffled green leaves.

The plant grows to a height of 2-3 inches.
The tubers can be planted in August and September.

The Winter Aconite can be planted in groups under shrubs and deciduous trees.
It prefers well drained soil and can be positioned in sun or partial shade.
Winter Aconites look great when planted with Snowdrops.
