Walnut trees have a growth inhibiting chemical called juglone. Many, many plants are sensitive to this chemical, but some are tolerant. Be careful not to plant too close to the trunk of your tree - the surface roots will compete with your new plants for moisture and nutrients. Plants tolerant of juglone include bee balm, begonia, bellflower, bergamot, chrysanthemum, coral bells, Shasta daisy, daylily, wild ginger, orange hawkweed, hollyhock, hosta, lamb's ear, morning glory, pansy, phlox, marigold, spiderwort, violet and zinnia.
