Chasteberry Vitex agnus-castus
ABOUT
Vitex agnus-castus, commonly known as the chaste tree, is a deciduous shrub with a multi-stemmed habit. The chaste tree exhibits a rounded and spreading form with a dense and bushy appearance. The leaves of the chaste tree are palmately compound, which means they have multiple leaflets that spread out from a central point, similar in shape to a human hand. There are typically five to seven leaflets, each with a lanceolate or narrow ovate shape, and margins that can be smooth or finely serrated. The foliage is aromatic when crushed, and the color is a vibrant green, adding to the plant's overall lushness. During the blooming season, the chaste tree showcases tall, upright spikes of small, fragrant flowers at the tips of the branches. These flower spikes are typically lilac, purple, or white in color. The individual flowers are tubular and form clusters along the spike, creating a showy and prominent display that can attract pollinators like bees and butterflies to the garden. As the flowering season ends, the chaste tree produces small, brown to black seed-like fruits, which are often referred to as peppercorn-like because of their appearance and size. The bark of the chaste tree is brownish-gray, which contributes to the woody and robust character of the shrub. Overall, the chaste tree's attractive foliage, striking flower spikes, and hardy fruits make it a visually appealing plant in various landscape settings.

- Water
The Chaste Tree should be watered deeply once a week during its growing season, which is in the spring and summer months. Provide the tree with about 1-2 gallons of water per watering session, depending on the size of the tree and the weather conditions. During the dormant season in fall and winter, reduce watering to every other week, unless there has been significant rainfall. Allow the soil to dry out between waterings to prevent root rot. It is crucial to avoid overwatering the Chaste Tree, as it prefers well-drained soil and is drought-tolerant once established.
- Light
The Chaste Tree thrives in full sun exposure, requiring at least six hours of direct sunlight per day for optimal growth and flowering. The best spot for the Chaste Tree is an open area away from larger trees or structures that could shade it. Partial shade is tolerated but may result in fewer flowers and a less dense growth habit.
- Temperature
The Chaste Tree is hardy and can withstand a range of temperatures, with an ideal growing range between 60°F and 90°F. It can survive temperatures as low as 10°F, but growth will be inhibited, and it may not survive prolonged freezes below this temperature. In the hottest regions, this plant can tolerate temperatures well above 90°F without significant stress.
- Pruning
Prune the Chaste Tree to maintain its shape and encourage flowering. Prune in late winter or early spring before new growth starts. Cut back the previous year's growth significantly, as flowers develop on new wood. Pruning can be done annually, or every few years, depending on the desired size and shape of the tree. The best time for pruning is after the threat of the harshest winter weather has passed.
- Cleaning
As needed
- Soil
Chaste tree thrives in well-draining soil with a pH of 6.0 to 8.0. A mix of garden soil, compost, and perlite or sand can enhance drainage and fertility.
- Repotting
Chaste trees growing in containers may need repotting every 2 to 3 years, preferably in the spring before new growth begins.
- Humidity & Misting
Chaste tree is tolerant of a wide range of humidity levels and typically does well in the average outdoor environment without needing specific humidity adjustments.
- Suitable locations
Indoor
Provide full sun, well-draining soil, and space to grow.
Outdoor
Plant in full sun, ensure well-draining soil, and give room to expand.

- Life cycle
The life of Vitex agnus-castus, commonly known as the chaste tree, begins with seed germination, which occurs in warm, moist soil conditions primarily in spring. The seedlings grow rapidly and develop into juvenile plants with characteristic digitate leaves and a strong root system. As the chaste tree matures, it enters a vegetative stage, wherein it produces woody stems and a fuller canopy through multiple growing seasons. The reproductive phase is marked by the development of fragrant lavender-colored flowers in summer, which attract pollinators and eventually give way to small, brownish-black, peppercorn-like fruits. After pollination and fruit set, the seeds within the fruits can be dispersed by various means, including birds and gravity, to begin a new life cycle. The plant may enter a period of dormancy during the colder months, especially in the more temperate edges of its growing range, but it typically retains its leaves in milder climates.
- Propogation
Propogation time
Spring to Summer
The most popular method for propagating the Chaste Tree or Vitex agnus-castus is by seed or by semi-hardwood cuttings taken in late summer. For seed propagation, the seeds should be sown in fall immediately after harvesting, to allow for natural stratification during the winter months. When it comes to cutting propagation, one would take a 4-6 inch (approximately 10-15 centimeter) cutting from the current year's growth, strip the leaves from the bottom half, and dip the end in rooting hormone. The cutting should then be planted in a well-draining soil mix and kept moist. Adequate root development usually occurs within a few weeks to a couple of months, after which the cuttings can be transplanted to a permanent location.
