These plants have long, pliable stems and are used to cover walls, fences, eaves, arbors or pergolas. Some cover by twining around structures while others have tendrils or aerial rootlets for clinging to walls or fences. Use these versatile plants to provide a vertical element in the garden and to soften the look of walls and other structures. Plant fragrant flowering vines by a window or seating area to bring fragrance to the garden, especially on warm summer evenings. Vanilla, jasmine or citrusy scents, plant these vines in just the right spot to take advantage of their wonderful aroma.
