Blue Chalk Sticks

Blue Chalk Sticks, scientifically known as Senecio serpens (often still found under its older name, Kleinia repens), is a distinctive and highly popular succulent known for its unique coloring and texture. This spreading succulent is native to the coastal and semi-arid regions of South Africa, where it thrives in well-drained, sandy soils and full sun exposure. As a long-lived perennial, it forms dense, mat-forming colonies that can cover significant ground over many years.

The most striking characteristic of Blue Chalk Sticks is its cylindrical, pencil-like leaves, which are a remarkable powder-blue to blue-green color, often with a waxy, glaucous coating that gives them a soft, almost frosted appearance. These fleshy leaves grow densely along sprawling stems, creating a distinctive texture in the landscape. The plant typically reaches a height of 1 to 2 feet but can spread much wider, forming an attractive groundcover or spilling elegantly over the edges of containers and walls. While primarily grown for its striking foliage, mature plants may occasionally produce small, inconspicuous white flowers in late summer or fall, borne on slender stalks. Blue Chalk Sticks is an exceptional choice for xeriscaping, rock gardens, coastal landscapes, and container arrangements, prized for its unique color, drought tolerance, and minimal maintenance requirements.
