Award-winning Colchicum speciosum 'Atrorubens' is a fall-blooming Colchicum which bears large, goblet-shaped, amethyst-purple flowers with a luminous white throat. Appearing long before the leaves, the attractive blooms are borne on deep purple stems. This cormous perennial makes a truly unique display in the late summer to early fall garden. Resembling crocuses with its cup-shaped flowers, it produces its strap-like foliage, way later, in spring. Ridiculously easy to grow, all parts of this plant are poisonous, therefore it is diligently ignored by hungry deer, rabbits, and other critters.

- Easily grown in average, medium moisture, well-drained soils in full sun or part shade.
