  • Description

  • Notes

Dwarf crested iris is lovely little iris that is low growing (3 to 6 inches) but can spread rapidly via a network of branching rhizomes, to form a dense groundcover. Pale blue to violet flowers with yellow crests on the falls appear mid spring. Leaves are narrow and sword-like, and are green to greeninsh yellow. Well suited to part-shade shrub borders, in woodland gardens, or rock gardens.
Grow in well drained soil in full sun to part to light shade, though best growth occurs in part shade. Prefers sandy-loam soils; but will grow in clay-loam soils as long as it is well drained. Drought tolerant in part shade. Deer resistant.
