Summary

Jatropha macrorhiza, commonly known as Ragged Nettlespurge, is an evergreen perennial herb native to rocky slopes, canyons, and desert scrublands in the Southwestern USA and Northwestern Mexico. It typically grows to a height of 1-2 feet (0.3-0.6 meters) and a width of 1-3 feet (0.3-0.9 meters). This plant is characterized by its deeply lobed leaves and thick, tuberous roots. The pink flowers it produces in the summer are small but numerous, creating a delicate display against the coarse foliage. The plant also bears fruit that is a three-lobed capsule containing seeds.

Ragged Nettlespurge is valued for its drought tolerance and unique appearance, making it a suitable choice for xeriscaping and rock gardens. It is often used in cultivation for its interesting texture and form, as well as its ability to thrive in challenging conditions with minimal care. Gardeners should plant it in well-draining soil and provide it with full sun to part shade to ensure optimal growth. While it requires medium amounts of water, it is important to avoid overwatering to prevent root rot. One should be cautious as all parts of the plant are toxic if ingested, and its sap can cause skin irritation.CC BY-SA 4.0
