Liatris spicata

(dense or marsh) blazing star, (Kansas, prairie, or spike) gay feather, button snake root, button snakewort

Clump-forming herbaceous perennial, native to moist habitats in eastern USA and parts of Canada. Long flower spikes with rosy purple, fluffy flower heads. From early summer, flowers open gradually from the top of the spike downwards. Grass-like leaves, mid green, 10-30 cm long, becoming progressively shorter along the flowering stems. Several cultivars are available, including white flowering, and dwarf forms. Attracts butterflies, bees, moths and hummingbirds.

Liatris spicata has numerous synonyms, including Kuhnia spicata, Lacinaria spicata, Suprago spicata, and Serratula spicata.

Prefers a sunny position in any moist, but well-drained soil. Also grows well in partial shade, and, except in sandy soils, is able to cope with some drought. Cut back to near ground level after flowering. Can be propagated by dividing the tuberous roots in early spring. Frost hardy.

Looks best when planted in groups in the middle of borders, in particular when combined with plants that have different flower shapes, such as daisies, Echinacea, and dahlias. Suitable for coastal gardens. Long-lasting cut flower, and can be dried too.
