Dense blazing star, Dense gayfeather, Marsh blazing star

Asteraceae (Aster Family)

USDA Symbol: LISP

USDA Native Status: Native to U.S.

Dense gayfeather or marsh blazing star is an erect, slender perennial reaching a height of 3-4 ft. The linear, grass-like leaves are clumped toward the base of the plant, but extend up the stem to the showy flower cluster. A tall spike of rayless, rose-purple (sometimes white), closely set flower heads. The purple, tufted flower heads are arranged in a long, dense spike blooming from the top down.

The species name describes the elongated inflorescence, with its crowded, stalkless flower heads. The protruding styles give the flower an overall feathery appearance, hence its alternate name, Dense Gayfeather.

Mr. Smarty Plants says

Question: I bought a liatris spicata start a month ago, and transplanted it into my front yard (full sun, clay soil, moist due to all the rain recently). The plant immediately wilted so I transplanted it in a pot filled with organic potting soil on the porch, in full sun again. The plant perked up for a week, and then started wilting again and now appears to be close to death. The weather has been a bit cool, but usually no colder than 50 degrees at night, and up to 70 during the day. Any idea why my plant is not happy? Could it be some sort of insect, or too much rain?
