Homeowners across the Gulf Coast spend hours planning flower beds, trimming shrubs and mulching walkways, yet many gardens still feel like they’re missing a finishing touch. Local horticulture experts say the solution may be one of the most overlooked elements of Southern landscaping: the perennial climbing vine.
Vines have long been part of the region’s gardening heritage, softening fences, arbors and porch railings the way a well-chosen accessory completes an outfit. In the warm, humid climate of coastal Alabama, which falls mostly within American Horticultural Society zones 8 and 9, a wide range of climbing and trailing perennials thrive with relatively little maintenance once established.
Among the most popular options is clematis, a genus with dozens of varieties suited to different growing conditions. Clematis alpina is a deciduous vine prized for its long stalks and one- to three-inch flowers in a range of colors. Clematis integrifolia stays more compact, reaching about three feet tall with blue, urn-shaped blooms roughly an inch and a half wide, and performs well across a broad span of growing zones. For shadier spots, Clematis armandii can climb to eight feet and produces fragrant pale pink flowers on long stalks. Clematis lanuginosa often blooms twice a year, in spring and again in summer, and tends to produce larger flowers than other clematis varieties, though gardeners should watch for clematis wilt, a fungal disease that can also spread to other plants in the garden.
Nita Crandall, a horticulture expert with Mobile Botanical Gardens, points local gardeners toward several other perennial vines well suited to the area. Crossvine, native to the central and southern United States, is a vigorous climber with long red and yellow tubular flowers that carry a subtle mocha scent; because it grows aggressively, Crandall recommends keeping an eye on it so it doesn’t overtake nearby plantings. Climbing hydrangea, a member of the hydrangea family native to the Southeast, produces small white flowers in late spring and summer and is often found naturally in wet, forested areas.
Yellow jessamine, also known as Carolina jasmine or evening trumpet flower, can climb nearly 20 feet and produces clusters of yellow, trumpet-shaped blooms, often with orange centers, that make it a favorite for arbors and walls in warm climates. Gardeners should note that the plant contains compounds toxic to humans and honeybees, so it should be handled and placed with care. A related plant, swamp jessamine, also called Rankin’s trumpet flower, is similarly hardy and can climb more than 20 feet with its own yellow blooms.
For gardeners hoping to attract wildlife, Lonicera sempervirens, commonly called coral honeysuckle, trumpet honeysuckle or scarlet honeysuckle, is a non-invasive evergreen that can grow beyond 20 feet and draws butterflies, bees and hummingbirds with its tubular flowers. Mobile Botanical Gardens carries a yellow-flowered cultivar of the plant, known as Sulphurea, in its on-site Marketplace for gardeners who want to add it to their own yards.
Manettia cordifolia, better known as Brazilian firecracker vine, is another favorite for South Alabama gardens. The easy-to-grow summer bloomer thrives in full sun to partial shade, reaching eight to 20 feet tall, and produces red, scarlet and reddish-orange flowers from one to two inches long that appear from late spring through fall. It also does well in large containers, making it a popular addition to hummingbird gardens on patios and porches.
Rounding out the list is Amethyst Falls wisteria, a non-invasive variety that can grow more than 30 feet and produces clusters of purple flowers that, from a distance, resemble bunches of grapes. It blooms in spring and, with light trimming, can flower again in summer. The vine tolerates full sun to partial shade and can be trained onto fences, arbors or trellises, and it is a strong draw for butterflies.
Gardeners with questions about selecting, planting or maintaining perennial vines can reach out to the Mobile County or Baldwin County offices of the Alabama Cooperative Extension System, both of which offer free guidance on plant selection and care. The Extension System’s Master Gardener Helpline is also available at 1-877-252-4769, or by emailing questions to coastalalabamagardening@gmail.com.
Local gardeners looking for inspiration can also visit Market in the Square, held Saturdays through July 28 from 7:30 a.m. to noon at Cathedral Square in downtown Mobile. In addition to local produce, homemade bread, jams, preserves, honey, crafts and live music, shoppers can stop by the Master Gardener tent for gardening advice. Mobile Botanical Gardens also posts information on upcoming fall classes and events at mobilebotanicalgardens.org.
