Caputia tomentosa, formerly known as Senecio haworthii, is a small succulent shrub with woody stems and attractive cylindrical leaves. It grows up to 1 foot (30 cm) tall. Leaves are upright, thick, fleshy, and pure white due to the fine white hairs covering the leaf surfaces. Flowers are bright yellow and appear on a short terminal inflorescence.
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Established Senecios 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 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. In very early spring, you can prune them back to where the stem is firm. 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 and constant moisture to germinate. Cuttings are easier and faster. Cut during the growing season, from early spring to fall. Root in sandy soil, in containers.
