Curio rowleyanus (Senecio rowleyanus), also called String of pearls, is an excellent groundcover for dry rock gardens or for edging garden paths. It is a low-growing plant, and can cope with a variety of light exposures, from full sun to semi-shade. It has attractive white and off-white flowers that are highly fragrant, and its small succulent leaves are low maintenance and thrive in dry, sandy conditions. In the right environment, this plant can quickly spread and form a beautiful, green tangle that adds texture and scent to the landscape.
Plant is native to South Africa, and is hardy in USDA Zone 9-11. Plants in colder climates should be grown in pots and brought inside during the winter months. Potted plants require well-drained soil. Water the plant when the soil is dry to the touch, reducing watering even further during winter when the plant is resting.
Overall, Curio rowleyanus is a great choice for those looking for an aromatic, drought-tolerant groundcover for gardens or containers. With its colourful and fragrant flowers combined with its low-maintenance attributes, this plant is sure to add interest to any outdoor space.
