German Iris Black Swan

German Iris Black Swan

A recipient of numerous awards prior to and after its introduction in 1960, this well-branched, time-tested cultivar yields several large, nicely proportioned blooms in mid to late spring. These sleek, velvety flowers are reddish black with brown beards, giving them an air of mystery. Because they open on 35" tall stalks, the elaborately frilled blooms are ideal for planting in a back border. Our gardening and landscaping pros suggest planting Black Swan in groups where its rich tones will provide a dramatic contrast with neighboring, lighter irises. Because it's gorgeous in floral arrangements, be sure to set some aside for your cutting garden!
  • Hardiness Zones 4-9
  • Mature Height 35 inches
  • Bloom Time Midseason flowering (Mid to late spring)
  • Light Requirements Full Sun, Half Sun / Half Shade
