The finest native iris for shade. flowers appear to rise directly from the forest floor in April, and the colony spreads steadily to fill the woodland ground layer.
Dwarf Crested Iris blooms so low to the ground that the lavender-blue flowers seem to rise directly from the forest floor with no stem at all, a charming effect unlike any other spring wildflower. The crested yellow and white markings on the falls guide bees into the flower with precision. Despite its small size, a colony in bloom is genuinely stunning, a carpet of iris color in April beneath just-leafing trees. It spreads vigorously by rhizomes to form a dense ground layer over time, making it an excellent native groundcover for shaded slopes and woodland gardens. The narrow, bright-green sword leaves are attractive through the summer and stay tidily upright. Extremely deer resistant: the rhizomes contain compounds that deer find objectionable. One of the best spring-blooming natives for a shaded landscape.
A nursery-grown plant, ready for the ground.

Care notes for dwarf crested iris.
Plant in partial shade in moist, humus-rich, well-drained soil. Keep consistently moist through spring but tolerates drier summer conditions once established. Divide every three to four years in fall to maintain vigor and expand the colony. Plant rhizomes just at the soil surface. burying too deep reduces bloom. Trim back old foliage in early spring. Very low maintenance once established.
