Iris cristata . . Crested Dwarf Iris
. . 4 to 6 in. . . Lt. to mod. shade
. . Zones 5 to 7 . . Avg. soil, well drained . . Spring
Native
Pale blue flowers in mid-spring. Spreads with rhizomes to form colonies. Use for ground cover, on banks, edging, or in rock gardens.
A versatile plant, this species will do well in poor soils and with little care. I have read Crested Dwarf Iris blooms best under these conditions. Yet, my propagation bed is over-fertilized, in full shade, thinned regularly and is still covered with flowers every spring.
The acrid roots were chewed by hunters to alleviate thirst.
