Description

The 2 to 3 inch diameter flowers are held atop very sturdy stems throughout the warmer months. When not in flower, the upright and arching narrow evergreen leaves form an attractive clump that provides a nice vertical accent in the landscape year round.

This Iris will tolerate short dry periods however prefers a consistently moist to wet soil for best performance. May grow outdoors in USDA Zone 8b with liberal mulching.
