Answer: You could use one of the larger clematis or possibly a nonflowering vine such as Parthenocissus. With sandy soil you will want to add organic matter such as compost at planting time and take care to water as needed to keep the soil moist like a wrung out sponge while the plant becomes established. Also, mulch over the root area with several inches of organic mulch. It should be about three inches thick in a flat layer, do not allow it to touch the stems. This will help reduce watering needs and also help feed the soil slowly over time as it breaks down. Keep in mind that perennial vines take several years to become well established and really grow and bloom their best. For quicker coverage you could try an annual vine such as morning glories.
