Iris sibirica, ‘Caesar’s Brother’

This tall Siberian Iris, ‘Caesar’s Brother’ produces beautiful, deep velvety purple flowers in late spring on rigid stems, which rise to 42″ high above a clump of arching, narrow, grass-like, linear leaves. Clumps will grow together and snuff out weeds. After blooms are gone, the vase-shaped foliage will retain its slightly bluish-green color into the fall. Iris “Caesar’s Brother” is one of the most easily grown Iris. Excellent cut flower, but lasts only 1-2 days. This plant will make very large clumps within a few years that carry masses of flowers.

Iris sibirica: Exceptional hardiness, easy culture, long life and durable, handsome foliage rank this perennial among the favorites. Performs well near streams, bogs or in open meadows, and blooms between spring flowering and summer flowering perennials.

Planting/Care Instructions +

Planting Instructions: Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly. Easily grown in average, medium wet 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.

Pests or Diseases: No serious pest or disease problems. Siberian iris is less susceptible to iris borer and soft rot than the tall bearded iris.
