Iris, Dwarf violet
This dwarf iris with blue to purple flowers in spring is native to the southeastern U.S. with outliers in surrounding states. It is sometimes confused with Iris cristata but has more upright narrower leaves and grows in drier habitats, often in pine woods. It is a charming little iris for the woodland edge where it will form colonies if the site conditons suit it.
