Allspice Tree (Pimenta dioica): Growing the "Three Spices in One"

Allspice—the dried berry of Pimenta dioica—delivers cinnamon, clove, nutmeg, and ginger notes in a single spice. Native to Central American rainforests, this evergreen tree is both a culinary treasure and a fragrant landscape specimen where climate permits.
