Care tips

It requires full sun for optimal flowering and well-drained, slightly acidic to neutral soil, enriched with organic matter. Watering should be regular during growth and flowering, keeping the substrate moist but not waterlogged. After flowering, it is advisable to reduce watering and lift the corms in cold climates for winter storage. A common mistake is planting them in heavy, poorly drained soils, which can lead to corm rot.
