I live in Shreveport, LA, which is north Louisiana. Lots of hot, dry, weather. I don't have the best sun in my yard, too many trees. Other knockouts in my neighborhood are really big and bushy but mine are not. When I purchased them the signs said they were knockouts. Otherwise they are nice plants, just don't have the size or all season blooming that I wanted. Maybe this year will be better as I have had several trees cut down so more sun. Thanks for your help.
