"We liked the idea of taking ordinary, low-cost objects and giving them another life," says Tarnapolsky, a landscape architect who is married to Jennings, a designer. "The wagons are light enough to move, they don't take up much room, and you can even wheel them indoors for parties. 'Here, pick your own salad, sit on the grass,' " she says. "And when you have kids, your pots can be toys again," Jennings adds.
Ideal for apartment-dwellers and perfect for beginning gardeners, containers should be practical as well as pretty. "It's so satisfying to grow food," Tarnapolsky says. "With herbs, you don't think in terms of maintenance. You're always nipping them to use. When they fade, it's time for winter lettuce, arugula, beets."
She and Jennings also appreciate the drought tolerance of succulents--a good quality in a container plant--and their sculptural leaves, which are especially striking in spare, rather than packed, arrays. The lawn, a fine turf with a tough constitution, will stay green in summer providing it's wheeled into the shade on hot days, and will turn gold when the weather cools.
"The long-term viability of pots is important to me," says Tarnapolsky, describing herself as a lazy gardener with little time to deadhead blooms. "But I can imagine experimenting--filling one wagon with just marigolds or lobelia and clear-cutting if they don't pan out."
