Non-Invasive Butterfly Bush ?
Just returned from Cape May, NJ, where we saw what I believe are Butterfly bushes pruned into trees. Absolutely exquisite. We would like to plant the same at home.
Does anyone know...
1) What variety is planted in the Cape May, NJ area - I believe zone 7?
2) Can anyone recommend a non-invasive variety for zone 7 Maryland?
3) Can anyone recommend a good variety for forming into a tree?
Any and all advice would be greatly appreciated, including if I am posting on the wrong forum :-)
