Santa Ana River woolly star occurs in the sandy soils of river flood plains or terraced alluvial deposits in the Santa Ana River drainage. Historically, it was known to extend along 60 river miles in Orange, Riverside and San Bernardino counties, but now plants occupy only about 18 linear miles of river floodplain along the Santa Ana River mainstem, City Creek, and Plunge Creek.
