This genus of 35 perennials from the daisy family (Asteraceae) is native to eastern North America. It makes a bold splash of color in summer and could't be easier to grow. Developing from corms or modified flattened roots, the plants form foliage clumps with simple linear to lance-shaped leaves that are sometimes finely hairy. Tall stems emerge from the clump, developing at their top numerous long, quite un-daisylike, bottlebrush spikes of filamentous purple-pink flowers. Bees and butterflies are attracted to the fluffy flower spikes. As well as being suitable for borders, Liatris plants are ideal as cut flowers. Native Americans used the roots medicinally, and early settlers found that the dried roots were effective for repelling moths. Common names include blazing star and gayfeather.
CULTIVATION
Most are very frost resistant. Wild plants are usually found along watercourses; cultivated plants are easily grown in any sunny position with moist, humus-rich, well-drained soil. Locate at the back of borders to disguise the foliage clump and make use of the flower stem's height. Propagate by division or from seed.
Top Tip
Liatris species will perform best in well-drained soil. This will also reduce the possibility of tubers becoming over-wet in winter.
