General Description

Striped sweet flag, or striped calamus, is an herbaceous perennial that is native throughout much of the United States and Canada. It has inconspicuous flowers and is grown primarily for its tall, upright, iris-like foliage that is beautifully variegated with cream striations. These plants spread by rhizomes and grow best in moist boggy areas with full to partial sun. Semi-aquatic in nature, striped sweet flag works well in naturalistic plantings along waterways or in gardens with moist fertile soil.
