Vitex Tree Plant. Mexican lavender, lilac chaste tree, hemp tree, sage tree, monk’s pepper, indian spice or vitex. Vitex may influence hormone levels in a number of ways.
In warmer climates, it can be trained grow as small, single trunk tree or a large shrub. Vitex is one of the most liberally reseeding plants i have ever grown. Chaste tree is not native to middle tennesse (it's actually native to the mediterranean region), but even though i generally favor native plants, i think more people should plant chaste tree.
