Colchicum atropurpureum

Colchicum atropurpureum is a small autumn-flowering bulbous plant whose pink blooms deepen to red-purple; it is often confused with Colchicum autumnale and its status as a separate species is unresolved. Grow it from bulbs in well-drained soil in a sunny to partly shaded spot, and keep it away from children and pets because all parts are highly poisonous.

Light

Water
Water during active growth in autumn and spring, then keep dry while the bulb rests in summer.
Soil
Well-drained, fertile soil or gritty garden loam.
Temperature
Hardy to about -15 °C when dormant; protect flowers from hard frost.
How easy
Easy
Safety
Toxic: All parts, especially the corms and seeds, contain colchicine, which can cause severe vomiting, organ damage and death if eaten.
