Gay feather or gayfeather, Liatris spicata (syn. Lacinaria spicata, Liatris callilepis, Serratula spicata), is also known as blazing star, button root, button snakewort, colic root, dense blazing star, dense button-snakeroot, devil’s bit, devil’s bite, marsh blazing star, prairie gay feather and prairie-pine. It shares the names blazing star and devil’s bit with the unrelated false unicorn root, and the name colic root with the also unrelated true unicorn root. It is not related to devil’s bit scabious.
The gay feather is an attractive purple flowered plant (cultivars are also available in colors ranging through pink to white) about 2 feet (60cm) tall, which is often grown as an ornamental. It requires moist or wet soil which is also well drained, and will tolerate any light to medium soil. It will not grow in full shade.
Gay feather has only three medicinal uses: as a gargle for sore throat, and internally to treat gonorrhea (clap) and kidney disease.
As with all herbs grown for medicinal purposes, gay feather must be grown organically to prevent its essential constituents being masked or entirely eliminated by the presence of foreign chemicals. To find out more about growing organic herbs visit the Gardenzone.
