Few hardy perennials are as widely adaptable as Siberian iris with its spectacular flowers and upright clumping form. The parent species of this variety is native to an enormous range from Central Europe through to Russia. The genetically complex Harpswell irises were hybridized by famed breeder Currier McEwen in Harpswell, Maine. Siberians are an adaptable clumping plant that tolerates both wet and dry soil conditions offering a versatile problem solver for cold climate gardens. This iris develops substantial tall clumps of linear blade-like, green foliage. After flowers fade the foliage remains far more lush and attractive than many other iris. These clumps will spread with time into sizable colonies that may be divided into many new plants.
In early summer these plants put forth many beardless three-part flowers in blue, yellow or white. These are held on tall stems just above the foliage tips. They make excellent cut flowers. Siberian iris prefers sunny locations and fertile soil with average drainage. It is quite cold tolerant and slowly spreads, so clumps should be divided every three years or so. Enjoy this vigorous perennial in any large, sunny bed or border. They look most impressive when planted in masses and as upright accents at the edge of water gardens and pools.
