Does anyone know if palms, or certain species of palms, can grow near black walnuts?
Black walnuts (Juglans nigra) put out an allelopathic compound known as juglone, which in the amounts that mature black walnuts put out, can kill many species of plants, such as tomatoes and rhododendrons. On the other hand, many plants are unaffected by juglone, and some, such as Kentucky bluegrass, actually thrive in the presence of black walnuts. Most (all?) plants in the walnut family put out juglone, but generally in non-lethal amounts, except for black walnut.
Any other experience with black walnut and other subtropicals (banana, yucca, broad leaved evergreens, etc.) would be good too.
