Growing Notes

'Coronation Anthem' shares the exceptional garden merits of the Siberian iris group: strong, upright stems that rarely need staking; clean, disease-resistant foliage that stays attractive from spring through fall; and a clumping habit that is well-behaved and non-invasive. These irises bloom in late spring to early summer, bridging the gap between spring bulbs and summer perennials. They are superb for mass plantings, waterside gardens (though they don't require wet soil), and mixed borders. The seed pods that follow the flowers add architectural interest to the late-season garden and can be used in dried arrangements.
