Tall Bearded iris are hardy perennials grown from rhizomes. They will survive in most climates but they do like cold winters. They are ideal plants for the southern states (VIC, TAS, SA), inland and high country areas of NSW and QLD, coastal NSW south of the central coast and Southern WA. They are not well suited to northern coastal NSW or coastal Queensland.
Bearded iris should be planted in a well prepared and fertile soil in an open position that gets as much sun as possible. Bearded iris are classified according to height of bloom spikes and bloom period. Dwarfs grow to a maximum height of 40cm, medians from 41cm-70cm and tall bearded irises are above 70cm in height.
