field bindweed ~ 07/14/11 ~ Hopkins

field bindweed / orchard morning glory
Convolvulus arvensis

This is my best guess and I could be totally wrong as to the ID. It is a low-growing plant with fuzzy leaves and stem. The bloom was smaller than other morning glories I've seen, but that could be due to the growing conditions right next to the Monterey Bay. The other hairy morning glory that grows in this area is the stemless morning glory (Calystegia subacaulis), but that's generally a white or cream flower. I have a feeling once I get better acquainted with morning glories, I'll be revisiting this ID.

ps 08/20/11 - Yep. I think I got this wrong. I discovered my mistake from looking up another morning glory/bindweed from Elkhorn Slough. I initially posted this as a native coast morning glory (Calystegia macrostegia ssp. cyclostegia). I tried to convince myself that despite photos not quite matching, that Jepson's description could apply. I've made the ID correction above for this invasive plant from Europe and Asia. If Wikipedia is to be believed this is the broader leaved Convolvulus arvensis var. arvensis. Seriously, how does one tell the difference between Calystegia and Convovulus?
