Spiny chloracantha contains a single species. It is distributed in the southwestern and south-central United States, most of Mexico, and much of Central America. Spiny chloracantha is a perennial herb or subshrub. The stems are hairless and sometimes waxy in texture, and some of the lateral branches may be sharply angled and reduced in size, becoming thorns. The alternately arranged leaves persist for only a short time and then fall away. They bear loose arrays of many flower heads. The fruit is a cypsela with a pappus of many barbed bristles.
Water:
Spiny chloracantha, from regions with periodic rainfall, efficiently absorbs and retains water. It requires consistent moisture without waterlogging and benefits from weekly watering. Thriving outdoors, spiny chloracantha adapts its water uptake during the growing season to promote optimal growth and health.
Propagation:
Spiny chloracantha propagates via seeds and cuttings, requiring adequate light, mild temperatures, and well-draining soil. Maintain proper moisture without waterlogging. For seeds, lightly cover in mix; for cuttings, use healthy, non-flowering stems. Ensure consistent indirect light and wait for root establishment before transplanting.
