Juglans nigra – Black Walnut – 3-Gallon
A well-known tree for reasons both good and bad. Walnut’s heartwood is valued for making beautiful furniture and its nuts are valued for their large size and tasty meat. Many walnuts have been planted around houses – visions of a hefty profit when they are harvested for their wood. High quality wood though is usually only obtained on 75-100 year old trees grown on limestone-rich, alluvial soils. Walnuts produce a chemical, juglone, that inhibits the growth of many other plants including most vegetables. Thus many homeowners find it difficult to garden in spots where previous owners planted walnuts as a cash crop.
