Purple Iris Growth


Irises come in many colors, but the rich purple iris produces a stunning effect in the garden with a sharp color contrast against green foliage. As like any colored iris, the flower stems grow from the base of the plant and produce spectacular flowers that dazzle garden-gazers. Even King Louis VII of France was inspired by the beautiful purple iris and its blooms to adopt the purple iris as a symbol of the royal house and insignia.

Bearded Irises

Bearded irises come in shades of purple and in nearly every hue of the rainbow. The type of bearded iris, rather than the color, is an indicator of size growth. Bearded irises grow from branching root stems called rhizomes.
