The common name of devil’s backbone is in reference to the zigzag stems that purportedly resemble a spinal column. Native from southern Florida and the Caribbean to Venezuela, this clump-forming succulent shrub or subshrub will grow in nature to 6’ tall and to 3’ wide. Indoors, it more typically grows to 2’ tall. Ovate to elliptic, medium green leaves (to 3” long). Showy, two-lipped, red bracts encase insignificant tiny scarlet flowers in late spring or early summer. Flowers are clustered at the branch ends. Fruits are small capsules. Plants rarely bloom indoors, however. Zigzag stems exude a poisonous milky sap when cut. ‘Variegatus’ has leaves with pink or white variegation.
No serious insect or disease problems. Watch for mealybugs or spider mites.
