Artemisia scoparia (Redstem wormwood) 9cm pot

Growth habit & appearance: Artemisia scoparia, known as Redstem Wormwood or yīn chén, is an elegant upright perennial recognised for its slender, red-tinged stems and finely cut, feathery green leaves. The foliage is aromatic when brushed and gives the plant a light, delicate texture despite its impressive height. In summer it produces small clusters of yellowish flower heads characteristic of Artemisia species. Its combination of height, colour contrast and soft foliage makes it a visually striking herb for any medicinal or ornamental bed.

Growing conditions: Fully hardy in Ireland, this species thrives in full sun to partial shade and tolerates a wide range of soils as long as drainage is good. Originating from Europe and Asia, it is well adapted to cool, damp conditions and grows vigorously once established, reaching well over a metre in a season. Supplied in a 9 cm pot, it should be planted out into open ground.

Traditional & herbal uses: Artemisia scoparia is referenced in traditional herbal systems for supporting fever management, hepatic function and metabolic balance, including associations with diabetes-related uses. The leaves and flowering tops are the parts commonly gathered, with yīn chén being a familiar preparation in East Asian herb practice.

Maintenance & harvesting: Cut back the plant once it has fully died back in autumn or winter to encourage a clean flush of new growth the following spring. Its tall habit benefits from occasional thinning of older stems to improve airflow. Harvest leaves and flowering tops during peak growth, typically mid to late summer. Once established, it requires minimal feeding—good drainage and periodic mulching are usually sufficient. Stake young plants in exposed sites if wind becomes an issue.
