Care tips
It prefers full sun exposure for abundant flowering and a well-drained substrate rich in organic matter. Water regularly during the growing season, keeping the soil moist but avoiding waterlogging, which can rot the corms. A common mistake is planting them in heavy, poorly draining soils, which seriously compromises their development and flowering. Protect the corms from frost if you live in cold areas.
