The defining feature of this iris is the prominent bushy beard running down the middle of each fall, a hallmark of the Tall Bearded group that makes every bloom instantly recognizable. Flowers are fragrant and showy, spreading to more than 5 inches wide with commanding upright standards and graceful hanging falls. The rhizomatous growth habit means the plant returns faithfully each season, and the reblooming tendency extends the display beyond the typical May bloom window. Once settled in, it handles drought and poor growing conditions with surprising resilience, and deer leave it untouched.
Tall Bearded Irises are grown primarily for ornamental display in gardens, valued for their architectural flowers and their role in traditional perennial borders. The fragrant blooms work well as cut flowers, bringing their elegant form and scent indoors.

Remove spent flower stems and any diseased or damaged foliage promptly to maintain plant health and vigor. After the final bloom of the season, trim back dead leaves to the base of the plant during annual fall cleanup. This practice helps prevent the onset of fungal diseases and reduces overwintering sites for iris borers and other pests.
