It's a good choice for heavy, wet soils and spreads to form dense colonies of upright stems bearing pink, rose, or white flowers from late summer into fall. It grows best in some shade, but tolerates full sun with adequate moisture.

Named for the Greek goddess of the rainbow, iris indeed comes in a rainbow of colors and in many heights. All have the classic, impossibly intricate flowers.
