My variegated gingers are outside under some trees. They are just coming back from a bad freeze we had a couple (?) of years ago. I see them planted in medians in full sun within the city. Mine barely get any sun and do well, even bloom from time to time. But their growth is stunted I think due to lack of sunshine. I didn't know they could be potted up. I might do that and them put them back where they are at least for the warm seasons, as I do worry about them in the winter. I keep them covered and for the most part they do well. They get regular water in the summer. But they have to fight the trees for it as they are at the edge of my driest bed, as a the circle of 4 large trees and a very large Youpon Holly surrounds the space. So massive amounts of water? Not mine. Full sun? Not mine. Perfect drainage situation? Not mine. But YMMV-Your Mileage May Vary.
