Historically associated with wetland and marshy places, but possibly in drier situations as well. Possibly silty loam and alkaline.. Meadows and seeps (sometimes alkaline) Riparian scrub (alluvial)
Change to CRPR 1B? All known occurrences are in irrigated landscapes. Discovered in Chino in 2011; originally identified as C. sepium ssp. binghamiae. Historical occurrences in LAS Co. should be searched for; needs field surveys. Threatened by transmission line development, housing development, and urbanization. Potentially threatened by hydrological alterations, weeding, and herbicide application. Not in TJM (1993) or TJM 2. See Madroño 59(1):25-27 (2012) for information on discovery (as C. sepium ssp. binghamiae), and Phytokeys 32:1-26 (2013) for original description.
