irises, perennials, gardens
Garden irises are hardy, long-lived perennials that need a minimum of care. They are an established “backbone” of home gardens because they bloom when few other plants do – after spring-flowering bulbs and before peonies, delphinium, and phlox. Irises are easy to grow and produce graceful flowers in a wide range of shapes, sizes, and colors. Several thousand cultivars of irises are available, so you can select those that will provide the colors you want in your garden.
