Siberian Iris

Iris sibirica

Siberian iris is tougher, more elegant, and easier to grow than bearded iris. Slender, grass-like foliage forms a graceful vase shape, and delicate flowers appear in late spring. No borer problems, no rot issues.

Full sun to light shade. Moist soil preferred but adapts to average conditions. Unlike bearded iris, plant rhizomes 1 inch below soil (not exposed). Divide every 4-5 years when center dies out. Leave foliage standing through winter for structure.
