Chaste Tree Seeds

The Chaste Tree (Vitex agnus-castus) is a beautiful, fast-growing ornamental tree or large shrub prized for its fragrant spikes of lavender, violet, blue, pink, or white flowers that bloom throughout the summer. Native to the Mediterranean region and western Asia, this drought-tolerant species is an excellent choice for pollinator gardens, attracting butterflies, bees, and hummingbirds. Chaste Trees are commonly planted as specimen trees, flowering hedges, or accents in landscapes where their long bloom season and aromatic foliage provide outstanding ornamental value.

Germination Instructions

Chaste Tree seeds do not require any pre-treatment before sowing. Plant seeds in a well-drained seed-starting mix and lightly cover them with approximately 1/8 inch of soil. Keep the growing medium consistently moist but not waterlogged and maintain temperatures between 70–75°F. Using a humidity dome will help maintain consistent moisture during germination. Seedlings should receive bright light once they emerge and can be transplanted outdoors after the danger of frost has passed.
