- Description
-
Dwarf Iris is a herbaceous, flowering, perennial native to the eastern United States. Depending on the variety, it is native to all regions of North Carolina. In native environments, it most often occurs in nutrient-poor acidic soils of open to semi-shaded woodlands. Dwarf Iris is a small, fragrant Iris with leaves that are narrower and straighter than those of Iris cristata, and blossoms that appear on short stalks in early spring before the leaves appear. Additionally the flowers lack the crested ridges that are found on the sepals and the flowers are strongly scented.
Dwarf Iris prefers sunny or shaded sites with moist, occasionally dry, acidic soil. It typically creates colonies of flowering plants from rhizomes that are deeply buried. Use this plant in the border of the native garden, but be sure to give it some afternoon protection from the sun.
Diseases, Insect Pests, and Other Plant Problems: No significant problems. Watch for slugs and snails.
