That was a great article, Admmad via Anne! It relieves my worry about the original 20 plants I ordered despite being more pleased by finding reputable vendors via this forum!! So now I'm back to figuring out how to fill a 30' border with those plants plus the 8 new ones I've ordered and the 11 extra perennials that are on the way. I think I better do more digging plans! Thanks, Anne!
