Marsh Morning Glory
Calystegia sepium ssp. limnophila
A perennial, summer blooming vine of marshy areas and streamside habitats, often rambling and climbing up cattails and nettles, which grow in similar habitats. This plant was assumed to be extirpated from Orange County, with only a few county records and the last being in 1932. But Ron Vanderhoff found it growing in the Santa Ana River area in 2013, and subsequently in four locations within Orange County, one colony east of Yorba Linda, and another in Huntington Beach.
Endemic to California
