Leaves are palm-shaped, up to 12 inches (30 cm) long, and have up to 7 inches (17.5 cm) long petioles. Throughout the growing season, clusters of pink flowers rise above the foliage.

How to Grow and Care
The key to growing successful Jatropha is to achieve the proper balance between moisture and drainage. They typically appreciate a steady water supply, but the most popular species cannot tolerate being submerged or soaked and quickly succumbing to root rot. Many of the popular Jatropha species make excellent small trees for a conservatory or sunny corner. Keep them well pruned so they don't outgrow their space too soon. Jatropha plants are vulnerable to pests, including aphids, mealy bugs, scale, and whitefly. If possible, identify the infestation as early as possible and treat it with the leave toxic option.
Jatropha can be propagated by seed (if you're fortunate enough to get sides) or by stem cuttings. To take stem cuttings, remove a small piece of stem, dip it in rooting hormone, then put into a small pot with seedling starter soil. Place in a warm, bright place and wait for new growth to emerge.
