This Oak Cliff garden shop, housed in a 1936 Conoco gas station, features an interior of houseplants, seeds, cacti, bulbs, furniture, pottery, and garden artwork, and a fenced backyard of trees, shrubs, perennials, antique roses, and water-wise plants. The focus here is on native and adaptive plants and organic gardening, and co-owner Elizabeth Cummings is on-hand to help customers learn all they need to know.
