Vitex agnus-castus (Chaste Tree) [15 Seeds]


Germination Information: I recommend these seeds only for gardeners who have experience with seeds that benefit from or require a chilling period. The easiest approach is to sow the seeds about 1/8″ deep in a pot in fall to early winter, setting it outdoors in a spot protected from mice so they can get a chilling period and then germinate when conditions are right in spring.

If you sow after January, give the pot a chilling period of a month or two.

It is also possible that these seeds could germinate (though perhaps at a less than optimal percentage) if you start them in very warm, moist, bright conditions, without a chilling period. But if you try that and no seedlings appear within 4 to 6 weeks or so, then try the artificial chilling period before moving them back to warmth and light.

Note that this information will not appear on the seed packet you receive.

Long appreciated for its herbal uses, chaste tree (Vitex agnus-castus) is pretty enough to be worth growing just for its ornamental features. In mild areas (roughly south of Zone 7), it can grow as a large shrub or small tree, reaching 10 to 15 feet tall. In Zones 5 to 7, it’s usually more of a medium-sized shrub. Winter cold can kill the stem tips partway or even all the way to the ground, but that’s okay because the plant blooms on new growth, generally reaching 4 to 6 feet by bloom time in mid- to late summer (continuing into early fall). Showy sprays of small, light purple-blue to medium purple flowers are a magnet for bees and butterflies. The palmately compound leaves are delightfully aromatic too. Full sun. Zones 5 to 10. Chaste tree may self-sow and is considered invasive in some areas, so you may want to do some further research before adding this shrub to your garden in mild climates.

Collected in late September 2022. At least 15 seeds.
