How to grow

Cultivation

Corms should be planted in moderately fertile, humus rich soil approximately 10cm deep and 7.5–10cm apart in groups to form clumps. Water if it is a dry season as a lack of water reduces flowering. This species is listed on Schedule 9 of the UK Wildlife and Countryside Act as an invasive, non-native species. While this does not prevent it or its cultivars from being sold in the UK, or from being grown in gardens, the RHS encourages those that do grow it to take great care with managing it and with disposing of unwanted material to ensure that it does not spread outside of the garden.
