Substitute for Butterfly Bush
I planted (2) butterfly bushes 2 years ago. The one in the shade is fine- but the one in full sun will grow to 7 foot tall in one summer after being cut down to 18". The "trunk" has become significantly large. Only recently did I learn that Buddleia is invasive.
Since the yellow bush is so out of control, I am planning on digging it up this fall. But what can I replace it with that will attact the butterflies and provide nectar to insects? How about lillacs?
The only other plants that I have that really attracts insects are sun flowers & sedum- the bees love them.
I am in zone 6, LI NY- the site is full sun with a clay sand soil.
