I have a buddleia that has outgrown its space in my garden and at the beginning of the season decided to take it out this winter. It's not particularly attractive, even in bloom which it is now. However, it attracts a huge amount of bees and butterflies : it can have a dozen butterflies fluttering around which is so joyous to watch.
Is there anything I can replace it with that will attract the insects but be more aesthetically pleasing?
