Tall majestic spikes of pure white flowers accentuated with a tangerine-red beard are of classic tall bearded iris form. A additional benefit is the delicate fragrance that most tall bearded iris possess. Bearded irises do best in full sun, well drained soils in Chicago area landscapes. Typically a planting will need to be divided every 3 to 4 years to provide enough fresh soil to support the heavy flower production. Iris borers can be a challenge for some gardeners and if present please consult your local nurseryman or call the Plant Information Desk at Chicago Botanic Garden for the latest in recommended control measures.
