I bought an Echinacea from wal-mart last year, because I noticed it had no petals on its current bloom at the time. I thought "how odd" and being the eccentric I am, I bought it, and observed it to not have any petals on any flowers the rest of the year. It's close to blooming now and am anxious to see if it'll be petal-less again. I was wondering if anyone has ever seen anything like this before. I'll take some pictures once the blooms are fully open (if you can call it open). One thing I did notice, is that it seemed the cone was slightly larger than my other Echinaceas (it is an Echinacea, trust me). I can't remember the label from when I bought it, but it was one of the more common cultivars, like Magnus or Bravado.
