Chaste Tree

The chaste tree (Vitex agnus-castus) is a lovely deciduous shrub that bears clusters of purple flowers in the summer. Vitex (chaste tree, Vitex agnus-castus) blooms from late spring until early fall with long, upright spikes of pink, lilac and white flowers. Any shrub or tree that blooms all summer is well worth planting, but when it also has pleasantly fragrant flowers and foliage, it becomes a must-have plant.Chaste trees need full sun and very well-drained soil. It’s best not to plant them in soil that is rich in organic matter because organically rich soils hold too much moisture close to the roots. Chaste trees do very well in xeric gardens where water is scarce. Once established, you’ll probably never have to water a chaste tree. Inorganic mulch, such as pebbles or stones, allows the soil to dry between rains. Avoid using organic mulches such as bark, shredded wood or straw. Fertilize the plant every year or two with a general-purpose fertilizer.
