Button Snake Root Liatris microcephala Play pronunciation

Dwarf blazing star is a small, upright, mounding, herbaceous perennial wildflower native to the Southeastern United States, found along the southern Appalachians. In North Carolina, this plant may be found in the western part of the state in acidic, rocky outcrops of granite or sandstone or in pine and oak barrens. Unfortunately, it is listed as critically imperiled in our state but is globally vulnerable. This plant grows 1.5-2 feet tall and up to 1 foot wide and has a woody corm. In the spring, it produces narrow, grass-like, deep green foliage. Erect, leafy stems develop in the late summer, producing terminal spikes with clusters of 4 to 6 rose-purple florets. Dwarf blazing star is a member of the daisy family (Asteraceae). The specific epithet microcephala means small head.

This plant prefers full sun and is adaptable to a variety of well-drained soils, but prefers a slightly acidic pH. It tolerates heat, humidity, drought, and poor soils. Dwarf blazing star is also deer- and rabbit-resistant. In wet winter areas, be sure to plant in well-drained soil to prevent the corms from rotting. It is winter-hardy in zones 6 to 9, but in colder regions, be sure to provide adequate winter mulch. Propagated by division in either the spring or fall. Deadhead spent flowers and cut back foliage in late winter or early spring.

Dwarf blazing star is appealing to pollinators such as hummingbirds and butterflies. It may be planted in butterfly and cutting gardens, native gardens, and naturalized areas. Consider planting as a vertical accent or mass planting along a border. Only purchase plants from a reputable nursery, and do not harvest plants in the wild.

Insects, Diseases, and Other Plant Problems:  Generally no significant insect pests or diseases. Monitor for aphids. Overwatering or poorly drained soils can cause root rot.
