Here's a beautiful way to plant native grapes that was brought home to me in stunning color while I visited Rancho Santa Ana Botanic Gardens on Jan 4. The juxtaposition of leaf colors in these native grape hybrids or cultivars takes this to a whole new level.
It's actually two grape vines planted together. I think that the beautiful red one is Vitis 'Roger's Red' a hybrid Ca native grape. I am less certain of the yellow / green one, but something like V. 'Walker Ridge' is a good guess based on its apparent vigor next to the more vigorous 'Roger's Red' and its leaf color.
