Cultivation:
For maximum freshness, please keep seed refrigerated in its original packaging until it is time to plant. Sow seed in containers in a coldframe. Gentle bottom heat can improve germination, 16-20°C. Grow on in any good well-drained but moist garden soil in full sun. Lift the corms in autumn in regions where winter temperatures are likely to drop below -15°C.
