Winter Aconite Bulbs are one of the earliest bulbs to bloom emerging deep in the glooms of February. Eranthis flowers resemble Buttercups but have a green collar at the base of the flower. Winter Aconite Eranthis Hyemalis are rather small and will benefit from a 24 hours soak prior to planting. Winter Aconite Spring Flowering Bulbs are ground covering bulbs creating an impressive carpet of yellow buttercup type flowers, ideal for woodland and rocky areas. Often Winter Aconites are flowering even before snowdrops.
