This is an ornamental grape, called Sweet Lace, purchased from Stark Bros; its leaves are quite fancy (see photo). The grapes are small, but so were my flame seedless grapes. These grapes have seeds, and taste fine, like any other grape, really.
Pot in this photo is 23 inches across and almost 20 inches high. Full plant with arch is just shy of 4ft high. This pot is actually the tubs my molasses licks come in for the horses. I have bunches of these, and the just pile up month after month. I use them for water tubs, feed bins (they have lids), and storage too. But, I also use them as planters. I just drill a hole on the side about 4 inches up from the bottom, and use them like earth boxes. I have 7 varieties of blueberry, 8 blackberry bushes, grapes, mini figs, raspberries, bananas, and some semi-tropical psudo-cherries. I have a drip irrigation system to water each tub.
