- Description
-
Blazing star is an erect perennial in the Asteraceae (daisy) family. It is clump-forming and grows up to 2 feet wide and 1.5 to 3 feet tall. Blooms appear midsummer to fall and flowers are fimbriated or dissected due to the protruding style branches. This Liatris has distinctive extra large flower heads, on long peduncles. The number of florets per head is greater than in most of the other blazing stars. The stems are stiff, erect, and loaded with short, grass-like leaves.
This plant requires full sun to light shade in well-drained soils. It is tolerant of heat loads and is intolerant of wet winter soils. It is best grown from corms rather than seeds.
This plant is found in dry woods and clearings in addition to being utilized in perennial beds, as a background plant, as a specimen plant, or as dried cut flowers. It adds a tall vertical accent to the back of the border.
Quick ID Hints:
- Tall, unbranched grassy stems
- Terminal spike of small heads
- Flowers are tubular and fringe-looking
Insects, Diseases, and Other Plant Problems: This plant has no serious pest or disease problems. Root-knot nematodes an occasional problem in southern gardens. Stems may need staking as they often lean with age.
