Bearded Iris (Rebloomers) Planting Guide
Bearded iris grow from rhizomes, not traditional tulip-like bulbs. Iris rhizomes are fleshy tubers that are planted on their sides close to the soil surface. Roots grow from the bottom side of the rhizome anchoring the plant and accessing nutrients and moisture from the soil. These roots need to establish before winter's cold descends on the garden. In freezing climates, late summer through early fall planting is an ideal planting time. In warmer areas, bearded irises may be planted through late October and early November. Late planted rhizomes may not bloom full strength their first spring, but catch up and produce normal flowering displays thereafter.
