General Description

The three-part flowers of Siberian iris ‘Harpswell Happiness’ feature refreshing, clear white standards and falls marked with creamy yellow bases. This lovely perennial was hybridized by famed breeder Currier McEwen in Harpswell, Maine.

The parent species of Siberian iris is native from Central Europe to Russia where it grows in a wide range of conditions from wet water's edge to well drained rocky hillsides. This versatility makes these tough perennials adaptable to a wide range of conditions. Siberian iris produce spectacular flowers in late spring to early summer in varying shades and combinations of blue, white, purple and yellow. Their clumps of linear, almost grass-like, green foliage remain fresh and attractive throughout the growing season.

Siberian iris prefer sunny locations and fertile soil with average drainage. The cold-tolerant plants form dense, slowly spreading clumps which should be divided every three years or so. These vigorous perennials look especially impressive planted in masses or as upright accents at the edge of water gardens and pools.
