Landscape: Marsh blazingstar is an easy landscape plant in that it does not have any serious pest problems and needs little attention as long as it is in moist soils. It does form clumps so be aware that it may need to be divided after many years.
Comments: There are four species of Liatris in the dunes. L. aspera blooms later than L. spicata. Because of the difference in flowering times, hybridization between the two species is rare but possible (Liatris X steelei Gaiser).
Etymology: The epithet name "spicata" is derived from the Latin word which means, "spikes or in spikes".
