Chaste berry is a plant which grows naturally in an area from the Mediterranean to Western Asia, however in the 16th century it was widely grown in England because of its potency.

Chaste berry (or agnus castus) is part of the vervain family of plants and is an aromatic shrub with long spires of pale lilac flowers and small grey/brown hard fruits (which look similar to black peppercorns).
