Vitex agnus-castus, commonly known as Chaste Tree or Chasteberry, is a deciduous shrub or small tree that is native to the Mediterranean region. It's known for its attractive spikes of fragrant flowers and is often cultivated for its medicinal and ornamental value. Here's a description and care guide for Vitex agnus-castus:

Description:

Leaves: The leaves of Vitex agnus-castus are palmately compound, with 5 to 7 lance-shaped leaflets. The leaves are grayish-green in color and have a slightly aromatic scent when crushed.
Flowers: The flowers are the main attraction of the chaste tree. They are produced in tall spikes (panicles) that can reach up to a foot long. The individual flowers are small and tubular, ranging in color from pale lavender to deep blue or violet, depending on the cultivar.
Growth Habit: Chaste trees can grow as multi-stemmed shrubs or small trees, typically reaching a height of 6 to 20 feet (1.8 to 6 meters). They have an open and airy growth habit with a rounded canopy.
Fruits: After flowering, Vitex agnus-castus produces small, rounded fruits that are often referred to as "chasteberry." These berries are not commonly eaten but have been historically used for medicinal purposes.

Care:

Sunlight: Chaste trees thrive in full sun. They require at least 6 to 8 hours of direct sunlight daily to produce healthy growth and abundant flowering.

Climate: Chaste trees are well-suited to warm and temperate climates. They are drought-tolerant once established and can tolerate a range of soil conditions.

Soil: Use well-draining soil that is moderately fertile. A mix of regular garden soil with added compost or organic matter is suitable. The pH of the soil should be slightly acidic to neutral.

Watering: Water newly planted chaste trees regularly to help them establish a strong root system. Once established, they are relatively drought-tolerant and require less frequent watering. Water deeply when the top few inches of soil feel dry.

Pruning: Prune Vitex agnus-castus in late winter or early spring to remove any dead or diseased branches and to shape the plant. You can also remove spent flower spikes to encourage new growth and repeat flowering.

Fertilization: Chaste trees generally do not require heavy fertilization. A balanced, slow-release fertilizer applied in spring can provide the necessary nutrients for healthy growth and flowering.

Propagation: Vitex agnus-castus can be propagated from seeds or by taking semi-hardwood cuttings in summer. Seeds should be sown in well-draining soil and kept consistently moist until germination.

Pests and Diseases: Chaste trees are relatively resistant to pests and diseases. However, keep an eye out for aphids or spider mites and address them promptly if necessary.

Medicinal Uses: Historically, chasteberry has been used for its potential to balance hormones and alleviate symptoms related to the menstrual cycle. Consult with a healthcare professional before using any plant for medicinal purposes.

Vitex agnus-castus is a beautiful and versatile plant that can serve as an ornamental focal point in your garden while also potentially providing herbal benefits. With proper care, including suitable light, well-draining soil, and occasional maintenance, your chaste tree can thrive and grace your outdoor space with its attractive foliage and fragrant flowers.
