Iris
Consider adding this native dwarf iris to your shade offerings; it blooms in time for spring sales and has great impulse appeal. Light to bright periwinkle blue flowers bloom on short stems. This plant spreads quickly by rhizomes to form a groundcover in moist woodland areas but is drought tolerant once established.
This fragrant, native iris can be found growing in moist to wet soils across much of the Eastern U.S. Its 3.5Ó flowers vary from light blue to deep violet with a yellow and white blotch and purple veining on the lower petals. It is easy to grow in rich, clay or sandy soils wherever consistent moisture is available.
