A native star of the spring season, Dwarf Crested Iris delights gardeners with vigorous lilac blooms on low growing, deer-resistant foliage. It’s perfect for both rock or woodland gardens, as it can be grown in part shade to full shade and spreads over time. In classic beds or borders, this sweet little iris should be placed front and center for prime viewing. (Iris cristata)

USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).

Plant Information

6-8” tall x 6-12” wide. When you see Dwarf Crested Iris in someone’s garden, you know they’re upping their game. This hardy little plant is often hard to find in garden centers, but isn’t difficult to grow – making it a uniquely easy accent for a sunny or partly-shaded spot. Strappy foliage rises to approximately six inches, then upward-facing blossoms open wide in shades of lilac-blue with a white and gold patch on the outer three petals. Like most iris, they should be planted with some of the rhizome visible above the soil in a well-draining spot. Dwarf Crested Iris is an early spring bloomer, and thus makes a wonderful companion for primroses, or ephemeral beauties such as trout lilies and trillium. It’s a vigorous spreader, and can be used very successfully as a ground cover, particularly in woodland gardens where the dagger-like foliage will not be burned by the sun. This classic, often hard-to-find North American plant, is great for wild gardens.
