need ideas for interplanting asters
I have a large front bed filled with asters, boltonia,and grasses (full sun,slight slope, DRY!) under a very young hawthorne tree that is totally bare right now. I would love to interplant with some spring bloomers but I'm not sure what would be appropriate. The only thing coming to mind right now is daffodils. I am looking for other suggestions. Maybe a spring blooming groundcover that will enjoy the shade come June/july? Other interesting bulbs?
