Iris 'Before the Storm' is a broadleaf deciduous perennial bulb / corm / tuber with green foliage. In spring black and purple flowers emerge. Features grassy texture. Grows well with sun and regular water. Prefers to be dry in summer. Does well in average and well-drained soil. A good option if you're seeking something verticillium wilt resistant.
One of the darkest purple-black irises available today bred from a cross between 'Superstition' and 'Raven's Roost'. Excellent growth habit and light fragrance. Winner of the Dykes Medal in 1996. Divide every two to three years just after blooming. Trim the foliage back to a third and plant the rhizomes at or just below soil level. Photo courtesy of Walters Gardens.
