I have a well-established bed of very large bleeding hearts that make a fantastic spring display in my upper Great Lakes region garden (zone 4-5). I always wait until they start to yellow before I cut them down to a few inches above the ground, which I did just this evening (August 4th). My frustration is that the bed is nothing but a tall sea of green from the time the spring blooms are spent until now. Do you have any suggestions for a companion plant that would follow the bleeding heart spring display and not be hindered by all of their foliage? The spot gets partial sun.
Thank you!
