Butter and Sugar Siberian Iris

'Butter and Sugar' Siberian Iris produce creamy yellow-and-white flowers borne on long stems above elegant clumps of green, sword-like leaves. Easy to grow and adaptable to a wide range of garden soils, 'Butter and Sugar' is a hardy, vigorous grower with roots strong enough to stabilize erosion-prone soils and steep banks. Tolerates part shade and resists both deer and rabbits. (Iris sibirica)
