Water
Water sparingly when dormant in summer. Increase watering in autumn as leaves emerge and during spring growth. Ensure soil drains well to prevent bulb rot, as these plants prefer dry summer rest.
Safety note: This plant may be toxic to humans and pets. See toxicity details.
Colchicum haynaldii is a fall-blooming perennial cormous plant native to the Balkans, featuring striking pink to lilac flowers emerging directly from the ground.

Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water sparingly when dormant in summer. Increase watering in autumn as leaves emerge and during spring growth. Ensure soil drains well to prevent bulb rot, as these plants prefer dry summer rest.
No significant pruning is required. Remove dead or yellowing foliage only after it has completely withered in late spring or early summer.
This allows the plant to fully store energy in the bulb for the next blooming cycle.
Propagate by division of corms in summer when dormant. Carefully separate offsets and replant them in well-draining soil. Seeds can be sown in autumn, but flowering may take several years.
Repot every 2-3 years, or when the pot becomes crowded. This is best done in summer during the dormant period. Use a well-draining potting mix, and ensure the bulbs are planted at the correct depth.
