Vitex negundo commonly called a chaste tree or nirgundi is a medicinal shrub or small, multi-trunked tree that typically grows to 10-15′ tall in warm winter climates. In cold winter areas, it is more often grown as a 3-5′ tall woody perennial. Features compound palmate, grayish-green leaves with 3-5 lance-shaped leaflets land tiny, fragrant, bluish-lavender lowers appearing in loose, 5-8″ long panicles in mid to late summer. This species is generally less ornamental than Vitex agnus-castus but maybe slightly hardier.
Planting & Caring –
Best grown in loose, medium moisture, well-drained soils in full sun. Plant in a sheltered location in USDA Zones 5-6 wherein this shrub is not reliably wintered hardy and often suffers winter die-back or dies to the ground in severe winters. May be regularly pruned to the ground in early spring and grown in the manner of an herbaceous perennial.
