Mentzelia pumila
Also called Golden Blazingstar, Wyoming Stickleaf, Dwarf Blazingstar
Dwarf mentzelia is a biennial wildflower of dry western North American landscapes, with bright yellow, glossy flowers that close at sunset. It is a wild native rather than a common garden plant, so growing it means matching its dry, sunny, well-drained habitat.
Mentzelia pumila, (dwarf mentzelia, desert blazing star, blazing star, bullet stickleaf, golden blazing star, yellow mentzelia, evening star, moonflower, Wyoming stickleaf, etc.) is a biennial wildflower found in the western United States and northwestern Mexico from Montana and North Dakota, south to Sonora and Chihuahua. It is a blazingstar and a member of the genus Mentzelia, the stickleafs; member species are also called "evening stars", but some stickleafs close at sunset, as does M. pumila.
Leaves of Mentzelia pumila are long, very narrow, and serrated-pinnate-like; also medium to light grayish green; an individual plant in an opportune site can be 1.5–2.5 feet (1 m) in height. The flowers are a bright, glossy medium yellow, and the major petals are variable, sometimes 5 major, 5 minor; also 4 and 4.
The root is a laxative. The Zuni people insert this plant into the rectum as a suppository for constipation. The plant is also used to whip children to make them strong so they could hold on to a horse without falling.
