Liatris spicata and pycnostachya difference?
Hello! I grow Liatris spicata and I noticed that some were different than the others; the others having purple stems right below where the flowers start. I was trying to find if it was another specie and I came across L. pycnostachya which looked extremly similar. I couldn't see any difference but the book said it had "reflexed, long-tipped involucral bracts." I have no idea what that means.... Could someone help me out please. I hate having miss-labled plants! btw: I planted half from seed and some from a bag of bulbs both labled Liatris spicata. Thanks for reading. ~David
