Leonurus cardiaca (Motherwort) 9 cm Pot

Growth habit & appearance:
Leonurus cardiaca forms a vigorous, upright perennial with square stems and softly downy, deeply lobed leaves. Pink-mauve whorls of flowers cluster along the upper stem nodes, drawing in bees and other pollinators throughout summer. Plants develop a substantial rootstock over time, forming stable clumps that persist for many years in Irish conditions.

Growing conditions:
Well adapted to Irish gardens, this hardy perennial thrives in full sun or bright partial shade and tolerates a broad range of soils, provided drainage is reasonable. Once established, it copes well with exposure and cool, wet summers typical of the west of Ireland. As a European native, it naturalises reliably when planted in open ground, though it benefits from a weed-free root zone in its early stages.

Traditional & herbal uses:
Currently used in modern herbal practice for its calming influence on the cardiovascular and nervous systems. It is commonly selected to ease stress-related palpitations, support emotional regulation, and help settle tension around the menstrual cycle. Contemporary literature also notes its value in promoting relaxation during episodes of anxiety or panic-type symptoms.

Maintenance & harvesting:
Keep the base weed-free in spring to encourage strong upright growth. Mature plants can reach 1.5 m, so occasional staking in exposed sites may be helpful. Cut back dead stems in late autumn or early winter. Harvest aerial parts when the plant is in full flower, selecting clean upper growth. Plants may self-seed lightly; remove unwanted seedlings or cut spent flower heads to limit spread.
