joann , I did not know echinacea was short lived. :(( .Congratulations on your free clump of purple echinacea! I do not have any carpet roses right now but it sounds like a good idea. I was thinking about a white clematis running on the ground, something with big flowers.
.Any suggestions?
Polymerous , sounds like you have a much bigger garden than my little corner garden but I am committed to cramming it full and having something that will bloom most of the time. I have mostly white's out front but did not consider the different bloom times at first so I never had any type of moon effect. I am going to loose a few grasses this year, they have gotten huge and will add the white daylilies and I also have a white Iris I will put in there, I might get a couple more because I do love them and I saw a white rebloomer somewhere. I was considering some trailing white Lantana and Dusty Miller. I am on a waiting list for the 'Ice Star' but I already have plenty of PowWow White, my clump started out with 25 flowers this year from two last year and the same thing happened with the purple. I purchased one purple echinacea from Home Depot and planted it one year and the very next year it has 25 flowers, they seem very vigorous. I did divide the purple but it has been slow getting started and I am wishing I had not done that.
