General Culture:
Easily grown in average, medium to wet soil in full sun to part shade. An adaptable plant which tolerates a wide range of soils. It is best grown in very moist, fertile, slightly acid soil, including boggy conditions, but will also tolerate a poor, dry soil because its thick roots penetrate the soil deeply.
Noteworthy Characteristics:
This tall Siberian iris produces deep purple flowers in late spring on rigid stems which rise to 40" high above a clump of arching, narrow, grass-like, linear leaves. Clumps will grow together and snuff out weeds. After bloom, the vase-shaped foliage will retain its green color into the fall. Excellent cut flower, but lasts only 1-2 days. Morgan Award winner (1953).
Problems:
No serious pest or disease problems. Siberian iris is less susceptible to iris borer and soft rot than the tall bearded iris.
Uses:
Mixes well with other perennials and provides excellent color and contrast to the perennial border. Also effective when planted on a slope or hillside or along a stream or pond. Massed plantings or well-placed specimens can enhance almost any setting, and the foliage provides lasting beauty after bloom.
