I grow this plant in native sandy soil in the CA Central Coast mountains. It does very well. Fast grower and heavy bloomer.
It intertwines with a white noisette rose over an arbor. The bark of the vine is also very attractive. I love this plant! I tend to garden with benign neglect and this seems to meet the needs of Calystegia macrostegia.

Nice large white flowers...Enjoy this in the 'wild' as it is one of those Calystegias that does not tame very well...
