Its stems are thick, erect, and purplish green. Senecio crassissimus has leaves that are long, flat, waxy and grey-green in color with vibrant purple edges. From mid-summer to fall, the plant produces bright yellow daisy-like flowers from stalks that are up to 2 feet (60 cm) tall.
Sun exposure: Full sun to Light shade
Soil: Porous and well-drained potting soil. Replenish nutrients in the soil every now and then.
Water: Water thoroughly when soil is dry to the touch, then let drain completely. Reduce watering to a minimum in the winter.
Fertilizer: Feed annually but lightly because too much fertilizer can cause etiolation.
Propagation: You can propagate K. anteuphorbium from seed or stem cuttings. Warm temperature at 55˚F / 13˚C and constant moisture are ideal for their seeds to germinate. Propagation from cuttings is easier and quicker. You should cut during the growing season from early spring to fall and let them root in sandy soil.
Hardiness: USDA Hardiness Zone 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (10 °C).
