Blue Chalk Sticks (Kleinia mandraliscae): A Ground-Hugging Succulent with Vivid Blue-Green Fingers

Blue Chalk Sticks, formerly classified as Senecio mandraliscae, is a low, spreading succulent that forms dense mats of cylindrical, powdery blue-green leaves resembling sticks of chalk. It grows 12–18 inches tall and spreads several feet, creating a stunning carpet effect. Small, white, rayless flowers appear in summer but are insignificant compared to the foliage. Native to South Africa, it’s invaluable for contrast in succulent beds, borders, and containers.
