About
Curio repens (syn. Senecio serpens) is a species of succulent groundcover plant in the genus Curio, in the Asteraceae family. Commonly named blue chalksticks, blue chalk fingers and also snake ragwort, it is frequently used in Mediterranean climate landscaping and as an ornamental plant. Its native range is the Cape Province of South Africa.
How to grow it
Drought tolerant, the plant is used as a ground cover, border plant or in a rock garden. It is grown in sandy, dry to slightly moist soils in sun or some partial shade. It is easily propagated by cuttings. Visually-similar to the ice plants of Mesembryanthemum, C. repens is typically found growing in and among rocky crevices and exposed ledges on dry, rubble-strewn sandstone slopes, where drainage is swift and sun exposure and airflow is high.
There is a hybrid of this and Curio talinoides that is known as 'Trident Blue'.
