Named after the world's largest waterfall, this showy, cobalt blue iris has heavily ruffled petals, white beards and a white patch at the center of each fall. It's impressive when planted in large groups—or mixed with other iris cultivars. Its lightly scented flowers also look elegant in cut-flower arrangements. Blooms in late spring to early summer and reblooms from late summer to early fall. Grows 40 in. tall with an 18-24 in. spread. Like other German or bearded iris, Victoria Falls Reblooming German Iris is a low-maintenance, deer-resistant perennial. It naturalizes well, and the plants can be divided every 3-4 years. Plant in full sun to partial shade. Bareroot. Zones 4-9.
