Perfect for adding a burst of color to the fall garden, Colchicum (Autumn Crocus) bears big flowers in shades of purplish-pink and white in September or October. 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.
