Can Flowers Be Planted Under Walnut Trees?

Walnut trees release juglone--a chemical that discourages competition by damaging nearby plants--into the soil. Many flowers, however, tolerate juglone. They include irises, hollyhocks, asters, phlox, chrysanthemums, tulips and sunflowers. Gardeners with walnut trees can create widely varied landscapes using these and other popular, juglone-tolerant flowers.
