Noteworthy Characteristics

Liatris graminifolia, commonly known as grass-leaf blazingstar or grass-leaf gayfeather, is a slender upright perennial that typically grows to 12-36” tall in the wild on unbranched stems clad with narrow, grass-like green leaves. Each stem is topped by a spicate terminal inflorescence of sessile to sub-sessile flowerheads from mid-summer to fall, each flowerhead containing 7-12 showy apetalous lavender purple flowers. This liatris is native to open woods, rocky woods, edges of swampy woods, pine barrens, slopes, stream margins, sandy fields, and roadsides from southern Pennsylvania and New Jersey south primarily along the coastal plain to Florida and Alabama.

Each flowering stem is topped from late July to October by a spicate inflorescence (terminal spike) of sessile to sub-sessile flowerheads, each containing 7-12 fluffy apetalous lavender purple flowers. Inflorescences bloom from top to bottom (bisipetally). Flowering stems rise up from basal tufts of narrow-lanceolate, medium to dark green leaves (to 12” long) which often have hairy fringed margins. Leaf length progressively shortens from stem base to inflorescence, with the upper stem leaves being needlelike to only 2-3” long. The flowers are attractive to hummingbirds, butterflies, and other pollinators, and the small seeds are attractive to songbirds.

Some authorities consider Liatris graminifolia to be a synonym of Liatris pilosa. Pilosa means covered with soft hair in reference to the internally pilose corolla tubes.

Genus name of unknown origin.

Specific epithet from Latin means having leaves resembling those of grass.

Liatris belongs to the aster family, with each flowerhead having only fluffy disk flowers (resembling “blazing stars”) and no ray flowers. The feathery flower heads of liatris give rise to another common name of gayfeather.


No serious insect or disease problems.


Native plant that is attractive in borders, cottage gardens, prairies, meadows and naturalized areas. Adds vertical accent and late summer to fall bloom.
