*groan*
I obviously didn't see this thread yesterday (or was it posted last night?).
I just went to a sale at my favorite nursery last night (20% off, got lots of things to fill in holes and for patio fall color, but they were sold out of the Echinacea which I was really going for), and now I saw this.
Sigh.
I just checked their website, and bookmarked it for future reference. If I can't get the Echinacea I want in one gallon size locally, then I will order the 4" ones from there.
Thanks for the info - I really want that Echinacea now!
