climate. In general 'Oncocyclus Section' Irises need good drainage, minimal summer rainfall and dry winters, similar to a semi-arid climate. In temperate areas (such as the Europe and America), they are only suitable for growing in specialist iris growers, within a bulb frame or greenhouse. They can be grown under glass (in frames), to protect the irises from excess moisture (especially during winter times) and also to ensure the (shallow planted) rhizomes get the best temperatures during the growing season. They can be grown in pots (especially in deep ones known as 'long toms'), but they need re-potting, every 2 years and extra feeding. Watering is one of the most critical aspects of iris cultivation.
