Native to wetlands of the southwestern U.S. and adjacent areas of Mexico. This vigorously spreading, low-growing perennial is a good choice for planting alongside a stream or pond; beneath a moisture-loving tree; or in a low, wet part of the garden. Tolerates alkaline and salty soils. Leaves and roots are used as a traditional medicine to treat a variety of ills.
Plants grow about 1 ft. tall and spread at least 2–3 ft. wide, eventually forming large, dense colonies. Upright stemshold thick, fleshy, deep green leaves 2–6 in. long; foliage has a strong, spicy, musty scent that is detectable from a distance on warm days. In late spring or summer, erect flower spikes rise just above the foliage mass, each topped with a conelike inflorescence dotted with tiny white flowers. Large, snowy white bracts at the baseof each spike give the impression of a single flower. The whole plant takes on reddish hues as weather cools, turning brick red by winter. Cut back or mow to the ground each winter for fresh spring growth.
