Liatris pycnostachya, Prairie Blazing Star


Did you know there is a Liatris, or Blazing Star, for every soil condition? Prairie Blazing Star is the one to choose for moist prairie plantings or, when planted in your garden, it receives adequate moisture. See Liatris aspera for dry soils and Liatris ligulistylis for medium soils. Of course, all of these can be grown in gardens and with the right soil conditions met; they are all relatively easy to grow.

In the above image, Liatris pycnostachya, Prairie Blazing Star was growing quite well, not at all irrigated, but with average summer rains and some roof runoff. But as drought began to set in in spring of 2020 and worsened in spring of 2021, it never returned. To the left of center in this photo, you'll notice a tall green spike -that is Liatris aspera, Rough Blazing Star. Despite the drought, in the very same location, Rough Blazing Star has done exceedingly well. Recap:
