alternate, basal (rosulate)

July - October
0.4 - 2.0
Inflorescence flowering from the top to the bottom of the stem.
A tall plant that lodges badly in cultivation. While germination is generally low among members of the genus Liatris, is can be improved by cold/moist stratification at 33-38 degrees F (1-5 C) for 30 days (Shirley 1994, Steffen 1997). There are 216,000 seeds/lb and the recommended planting rate is 10 lbs/acre. Plants bloom in 2-3 years from seed. Old plants with multiple corms can be divided with a knife and planted in sharp sand or sand/peat mix.
Attracts birds and many species of butterflies and skippers. Sulphur butterflies seem to be especially attracted to this species.
Common in pinewoods of Louisiana and Texas and no doubt occurred in upland areas of Louisiana's coastal prairies. Prefers well-drained, deep, sandy loams in mesic or mesic dry to dry locations with pH in the range of 5.5 - 7.5. The name "aspera" is Latin for "rough," referring to stiff hairs on the stem and leaves.
Dry open places, open woodlands, and sandy sites.
