This shrub has been in cultivation since Roman times; ‘Vitex’ was the Roman name for the Chaste Tree, now known botanically as Vitex agnus-castus. From classical Greek and Roman times this plant was known as an anaphrodisiac (the opposite of an aphrodisiac). In ancient Greece, it was called αγνος (ágnos), which apparently the early Christians confused with ‘αγνος (hagnós), chaste, and with the Latin agnus, lamb, the Christian symbol of purity. So, the plant received several sacred names in various languages, but all meaning ‘tree of chastity’.
We know it as one of the best of all summer-flowering shrubs with large fragrant panicles of lavender blue flowers. It naturally grows 3 metres tall by 2 metres across but as it flowers on new season’s wood it can be cut back hard in winter to keep it in more manageable proportions to suit smaller gardens.
‘Abbeville Blue’ is a particularly beautiful and long flowering clone.
