In keeping with her white/green color scheme in the backyard shade garden, Cantrell uses a white concrete container with Acanthus 'Whitewater' or bear's britches. This showy shade plant is zoned 7-10 which makes it borderline for her zone 7a garden. So, the bear's britches is still in it's black nursery pot and placed in this container for the summer. That makes storing it indoors for winter much easier. The ivy sets off the white and green.
