Dwarf crested iris (Iris cristata) is a native wildflower which blooms in the spring.  It grows in moist open woodlands in eastern and southern parts of the U.S.

The short plant -- in comparison to most irises -- grows about six inches tall when it's blooming.  Later in the year, the leaves grow to about eight or nine inches high.

Although the flowers are typically purple with white and yellow highlights on the sepals, Dwarf crested iris may grow flowers which are almost white.
