Summary

Ambrosia monogyra, commonly known as Singlewhorl Burrobrush, is a deciduous subshrub or shrub native to arid desert regions, often found in washes, alluvial fans, and scrublands in the Southwestern United States and Northwest Mexico. It typically grows up to 4 meters (13 feet) tall, with a sprawling habit that helps stabilize loose desert soils. The leaves of Singlewhorl Burrobrush are highly adapted to its dry environment; they are very thin, thread-like, and sometimes divided into thread-like lobes, which minimize water loss. The plant produces inconspicuous staminate flowers with translucent white corollas and more noticeable pistillate flowers that develop into rounded, fruit-bearing structures.

Singlewhorl Burrobrush is valued for its drought tolerance and ability to thrive in harsh desert conditions, making it suitable for xeriscaping and naturalistic desert gardens. It is also used for habitat restoration projects due to its soil stabilization properties. This plant prefers full sun to part shade and requires minimal water once established, making it an easy-care choice for gardeners in arid regions. It is adaptable to a variety of soils, provided they have good drainage. While not known for significant pest or disease problems, it can become sparse with overwatering or in too-rich soils.CC BY-SA 4.0
