IRIS - Iris
Iris is a diverse genus with many varieties and cultivars. The most well known Irises are those with a rhizome. These are readily available to buy from nurseries and garden centres. Less well known are the bulbous sorts. Since 2013 De Warande has begun to use these sorts for naturalising.
Irises prefer a fertile soil – loam or clay – and a sunny position. If you have a sandy soil then enrich every planting hole with leafmould or compost, as well as clay minerals.
