Summary
Ambrosia pumila, commonly known as San Diego Ragweed, is a semi-deciduous perennial herb that is native to the vernal pools, grasslands, and coastal sage scrub of Southern California and Baja California. It typically grows to a height of 0.2-0.5 feet and can spread 2-3 feet wide. The plant has a hairy appearance and is adapted to survive in its native Mediterranean climate with wet winters and dry summers.
San Diego Ragweed is valued for its low water requirements and ability to thrive in full sun to part shade, making it suitable for xeriscaping and naturalistic plantings in arid regions. It is often used in restoration projects due to its native status and ecological role in supporting local wildlife. Despite its common name, it is not as allergenic as other ragweed species, making it a more favorable choice for gardens. Cultivation requires well-drained soils, and the plant is drought-tolerant once established. It is important to note that Ambrosia pumila is considered rare and endangered in its natural habitat, so gardeners should source plants responsibly.CC BY-SA 4.0
