Species of Physic nuts


Coral plant

This plant has an added garden bonus, since it is a great attractor of butterflies. Care should be taken with coral plant, since it is slightly toxic, and should never be eaten.

Leatherstem
Leatherstem (Jatropha dioica) is indigenous to western North America. The plant contains a latex that changes from a translucent yellow color to deep crimson if you expose it to air. This accounts for the Spanish name for this species—“sangre de drago,” which means “dragon’s blood.”

Peregrina
Peregrina is a popular border and decorative plant because of its gorgeous red or pink flowers that bloom all year. This shrub, native to Cuba and widely propagated worldwide, attracts butterflies and hummingbirds. However, extreme caution is suggested because all parts of this plant are toxic when consumed.

Barbados nut
The barbados nut (Jatropha curcas) plant is cultivated throughout the world for ornamental uses because of its rapid growth.
