Description
Kleinia anteuphorbium is a summer-dormant deciduous succulent shrub that grows up to 5 feet (1.5 m) tall. It has cylindrical, arching, pale gray-green, segmented stems striated with darker longitudinal lines and small, gray-green, lanceolate leaves that lie appressed along the stems near the branch tips. In fall appear the very rayless flower heads that have white disk flowers with yellow stigmas and anthers.
Hardiness
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
Established Senecios are extremely drought tolerant. They 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, around 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.
