Use what you have, plant what you need. "Because I'm a landscape designer, I have 2 acres where I'm always planting new plants," says Jones. "When I plant something, I'm very conscious of whether it has a use. Like boxwood, magnolia, arborvitae, different types of pines. I can use these in my Christmas decorating." When she grows her own, she says, she can also be assured that the plants are very fresh.
