Motherwort (Cardiaca) is a remarkable herbaceous perennial in the mint family, long used in herbal traditions for heart health support, female reproductive balance, and digestive functions. Reaching up to 3 m in height, its robust, slightly spiny stems form a dense summer hedge that attracts pollinators with its small pink flowers, while helping to deter deer and other animals from garden beds. This plant is particularly well-suited to naturalized herb gardens or the back borders of ornamental beds.

Where can you grow Motherwort?
Ideal for zones 4 to 9, Motherwort grows well in full sun to partial shade and prefers well-drained, moderately fertile soil. It tolerates poor soils and readily self-seeds once established.

History and historical uses
Native to Central Asia and Southeastern Europe, Motherwort (Leonurus cardiaca) has been naturalized for centuries in many parts of the world. Traditionally used in European herbal medicine for anxiety, menstrual cramps, and palpitations, it remains a common plant in modern apothecaries. Its name "Motherwort" reflects its historical association with female reproductive health.
