Description

Notes from the NPA Border - this unknown Iris has striking blue flowers and 30" tall, strong foliage. Easily grown in moist, fertile, humusy, organically rich, neutral to slightly acidic, medium moisture, well-drained soils in full sun to part shade. Siberian iris is an adaptable plant which tolerates a wide range of soils, including boggy ones, but will generally perform well in average garden soils. Avoid soils that are too wet or too dry. In too much shade, plants tend to produce fewer flowers and foliage tends to flop. Best with consistent moisture from the onset of spring growth until several weeks after the flowers fade. Continue irrigation after bloom, however, to keep foliage clumps attractive. Rhizomes should be planted 1-2” below the soil surface and 1-2’ apart. In cold winter regions, plant the rhizomes in early spring or late summer. In mild winter regions, plant the rhizomes in fall. Divide plants as needed when overcrowding occurs and decreased flowering is evident. Remove flowering stems promptly after bloom unless the seed pods are considered to be an attractive addition to the garden.
