Senecio mandraliscae, also called Blue Chalk Sticks, is a succulent in the Asteraceae family native to rocky coastal regions of South Africa. It grows well in dry, well-drained soils with plenty of sun.
The pencil-thin cylindrical leaves are silvery-blue to blue-gray, slightly curved, and coated in a powdery farina that gives the plant its signature chalk-dusted appearance. It grows in a clumping, upright, and gently trailing habit that spreads generously, creating a soft, flowing groundcover effect or a cascading display from a hanging basket.
Small white to cream-colored daisy-like flowers appear on tall slender stems, typically in late fall to winter. The blooms can attract pollinators when grown outdoors; note that the plant produces pollen and allergens, so those with sensitivities should keep it in well-ventilated spaces.
Propagation is simple: snip a healthy stem, let the cut end callous for 24-48 hours, then plant it in dry succulent soil, and new roots establish quickly. Use it in container gardening, rock gardens, and sunny borders, or move it outside for summer where it does well in bright, partially sunny spots and handles balcony conditions well. Keep it on a high shelf or out of reach, as cats and dogs shouldn't nibble or eat the plant, and it's best placed away from small children.
