Laura Brown, who works at Bayberry Gardens in Truro, planted this container to create the illusion of cooler temperatures on hot days. She chose an aluminum trough for its watery silver color and brought together an array of greens, including Scotch moss, caladiums, a variegated fuchsia, and coleus. She added a creeping Jenny she had on hand, though the plant is not sold anymore because it’s been deemed invasive.
