Other names and notes
(Spiked Blazing Star). Blazing Stars of the Liatris genus have general characteristics of: Stem leaves narrow and lance shaped, the flower heads appear on a spike. Heads may be composed of 5 to 60 small tubular 5-lobed purple flowers. L. spicata can grow from 2 to 6' in height. The stems are smooth and the linear leaves can be up to 3/4" wide. Individual flower heads are small, only 1/2" wide with 6 to 10 pinkish flowers. The heads are not stalked and like L. pycnostachya, occur in a dense spike. Flower head bracts are rounded but like L. pycnostachya tend to curve backward. L. spicata and L. pycnostachya are difficult to distinguish without close inspection.

Notes: This species is not native to Minnesota, but is native to most states eastward. Eloise Butler first recorded planting this species in 1911 with plants obtained from Kelsey's Nursery on the East Coast and she planted more on May 1st 1912 - same source. Martha Crone planted also in 1936 and she listed it on her 1951 Garden Census.
