Ideas for underplanting hedge
I have a hedge planted at the back of my propery that contains hackberry, black walnut, and slippery elm growth. These are large trees that have been here for what looks like over 30-40 years. Was wondering if anybody has any ideas for vines, flowering shrubs, ferns, etc that will grow near these trees. Live in kansas, so get the worst temperature extremes. Also have very heavy red clay soil (although most likely in hedge much lighter). Thanks for any suggestions you may have.
