The Story

Plant Bio

Siberian irises are clump-forming perennials with narrow, grass-like leaves. They produce elegant, beardless flowers on slender stems above the foliage in late spring and early summer. They are valued for their hardiness and graceful appearance. An heirloom cultivar dating back to 1912, 'Perry's Blue' is celebrated for its classic, clear, sky-blue flowers with delicate veining on the falls. It is a reliable and vigorous grower, forming substantial clumps over time.
