It grows up to {{convert|3|ft|m}} in height by {{convert|1|-|2|ft|m}} in width.[3][4] It spreads by rhizomes, which can increase a colonies width substantially. The stems are thin, gray-green, often somewhat waxy, and grooved, and grow {{convert|30|-|90|cm|in}} in height. The inflorescence sprouts from the side of the stem, rather than its tip. It holds many flowers, each of which has short, narrow, pointed tepals and six stamens. It flowers in the summer. The fruit is a spherical red or brown capsule which fills and bulges from the dried flower remnants when mature. The seeds attract birds.
