- Description
-
Dense blazingstar is a perennial bulb in the daisy family (Asteraceae) that is native to the Southeast United States. It has a clumping, erect habit and grows 3 to 4 feet high and 10 to 18 inches wide.
It requires full sun, moist soil with good drainage, and a neutral to acidic pH. It tolerates occasionally wet or dry soil as well as heat, humidity and poor soil. Propagate it by division or seed.
The showy flower spikes may be pink, purple or white, and appear in summer. It differs from the typical species (Liatris spicata var. spicata) by having flowers that are more loosely spaced across the stem but still bloom from the top down. The flowers are attractive to butterflies, bees and hummingbirds and are also attractive when cut and dried. Goldfinches eat the seeds. It also serves as a host plant for the larvae of both the Liatris flower moth (Schinia sanguinea) and the Liatris borer moth (Carmenta anthracipennis).
Dense blazing-star is at home in many landscape locations including meadows, naturalized areas, recreational play areas and beside patios or ponds. It is suitable for small spaces. Use it in a border or mass planting in a cottage, pollinator, butterfly, rain, rock or native garden.
Insects, Disease and Other Plant Problems: No significant problems.
