Iva hayesiana is a species of flowering plant in the family Asteraceae known by the common names San Diego marsh-elder and San Diego povertyweed.
It is native to northwestern Baja California and southern California, in San Diego, Orange, Los Angeles, Ventura, and San Bernardino Counties. [2]
Iva hayesiana is a shrubby perennial herb approaching one meter (40 inches) in height. Its green oval-shaped leaves are fleshy, glandular, aromatic, and 3 to 6 centimeters (1.2-2.4 inches) long. [3]
The flowers are nearly invisible; male flowers have translucent corollas and simple yellow stamens and female flowers, if they occur, lack corollas altogether. This is a plant of mineral-rich waterways such as intermittent streams and alkali flats. [3]
Threats to the plant include development of coastal habitat and waterways. [1] It is a Vulnerable flora species in California.
This species is recommended for use as an ornamental plant in fire-resistant landscaping in Southern California. [4]
