Eranthus hyemalis - Winter aconite One of the first flowers to appear each January, Eranthis hyemalis is a tuberous herbaceous perennial which can spread to form large clumps and colonies where it’s suited. It can be grown under the shade of deciduous trees, and in light grass. The cup-shaped flowers are brilliant yellow, 1 ¼”/3cm in width, and surrounded by a charming ruff of rich green stem leaves, a wonderfully cheering sight in late winter, although the flowers do not open until the temperature reaches 10ºC. The basal leaves are also a rich green. Despite the name, it is related to buttercups, not aconites, and does not share the latter’s deadly toxicity. Divide ‘in the green’ and don’t let the soil dry out in summer. Holds the RHS Award of Garden Merit.
