Crown of Thorns

Crown of Thorns thrives in bright, direct sunlight and will bloom best when placed in a sunny window indoors or in full sun outdoors. Use a well-draining potting mix and allow the soil to dry out between waterings, as this plant is highly drought tolerant and sensitive to overwatering. Water thoroughly when the top inch or two of soil feels dry, then let excess water drain completely. Hardiness zones range from 9-11.
