Juglans nigra ‘Sparrow’ – Black Walnut – 3-Gallon
Especially flavorful variety with medium sized nuts that have very good cracking quality. ‘Sparrow’ is quick to bear, early ripening, a dependable producer, and hardy to -30° F. Illinois origin.
Black Walnut needs room to grow and a deep rich soil for best growth and nut production. They are not compatible with most vegetables and fruit trees because they produce a chemical, juglone, that inhibits growth of near-by plants. Self-fertile, but yields can be improved by cross-pollination with either seedling walnuts or a different variety.
