Senecio articulatus is an evergreen perennial up to 2 feet (60 cm) tall. It has pale grey green succulent stems with markings of darker green or purple, just below the petioles. The stems are tubular and jointed. If leaves do appear (approximately 50 % of the time), they are usually divided into leaflets and are succulent, green on top and purplish below. It bear yellow flowerheads, approximately 0.5 inch (1.2 cm) across, borne in small corymbs.

How to Grow and Care
Established plants are extremely drought tolerant. They do need some water, during the summer, but do not leave the soil wet for prolonged periods. Allow the soil to dry out between waterings in the winter, when they are somewhat dormant. Since they are growing in sandy soil, nutrients will need to be replenished. Fertilize annually, but lightly. Too much fertilizer will cause a lot of leggy growth.
Taller varieties can get floppy. You can prune them back to where the stem is firm, in very early spring. You can even root the cuttings.
Plants can be divided or repotted in early spring. If you are growing them in containers, they enjoy spending the summer outdoors. Wait until there is no danger of frost and move them back indoors in the fall.
Senecio can be grown from either seed or cuttings. Seeds prefer warm temperatures (55˚F / 13˚C). And constant moisture to germinate. Cuttings are easier and faster. Cut during the growing season, early spring to fall. Root in sandy soil, in containers.
Few pests bother Senecio. They can occasionally be affected by scale and mealy bugs. Rabbits found my String of Pearls quite tasty… – See more at: How to Grow and Care for Senecio.
