Curio repens, commonly known as Blue Chalksticks, is an evergreen succulent native to the rocky outcrops and sand dunes along the coast of the Western Cape in South Africa. It typically forms a dense mat reaching about 20 cm in height, with distinctive silvery-blue, finger-like fleshy leaves that contribute to its ornamental value. The small, round, pompom-like flowers emerge in clusters, primarily between spring and autumn, and are not particularly showy from a distance, appearing off-white with subtle yellow and pink tinges on the stamen when viewed up close.

Blue Chalksticks is valued for its drought tolerance and is commonly used as a ground cover, border plant, or in rock gardens due to its low-growing habit and attractive foliage. It thrives in sandy, well-drained soils and can tolerate dry to slightly moist conditions. While it prefers full sun to part shade, it is adaptable and can be grown in various light conditions. This plant is easily propagated by cuttings, making it a convenient choice for gardeners. It is important to avoid overwatering to prevent root rot. In regions where it is not native, care should be taken as it can become invasive in similar climates.CC BY-SA 4.0
