Best Plants for Trellises: Vertical Gardening Guide

Embarking on a gardening journey and considering vertical gardening? Trellises are an excellent way to maximize your garden's space and create visually appealing structures. But with countless plant options, choosing the right ones for your trellis can be overwhelming. Let's delve into the world of climbing plants and explore the best options for your trellis, ensuring a lush, thriving vertical garden.

Before we dive into the plant suggestions, let's briefly discuss what makes a plant suitable for a trellis. Climbing plants, or vines, typically have tendrils, twining stems, or adhesive pads that allow them to attach to supports and grow vertically. They also come in various sizes, colors, and textures, offering endless possibilities for creating stunning vertical displays.

Annual Climbers: Quick and Colorful

Annual climbers are perfect for adding instant color and coverage to your trellis, as they grow rapidly and bloom profusely throughout the growing season. Here are two popular annual climbers that thrive on trellises:

Morning Glories (Ipomoea purpurea)

Morning glories are classic annual climbers known for their large, trumpet-shaped flowers that open in the morning and close in the afternoon. They come in various colors, including blue, purple, pink, white, and bi-colors. Morning glories have heart-shaped leaves and produce twining stems that cling to trellises using tendrils. They prefer full sun and well-draining soil but are relatively drought-tolerant once established.

To encourage bushier growth and more flowers, pinch back the growing tips of morning glory plants when they're young. They can grow up to 10 feet tall, making them ideal for covering large trellises or arbors. Morning glories are also known for their ability to attract pollinators, such as bees and butterflies, making them an excellent choice for creating a vibrant and eco-friendly vertical garden.

Black-Eyed Susan Vine (Thunbergia alata)

Black-eyed Susan vine is another stunning annual climber that produces trumpet-shaped flowers with yellow petals and dark centers. This vine is a vigorous grower, producing masses of blooms from summer to fall. Black-eyed Susan vine has heart-shaped leaves and produces twining stems that cling to trellises using tendrils. It prefers full sun to partial shade and well-draining soil but is relatively adaptable to various growing conditions.

Black-eyed Susan vine can grow up to 10-15 feet tall, making it an excellent choice for covering large trellises or creating living walls. To encourage bushier growth and more flowers, pinch back the growing tips of young plants. This vine is also known for its ability to attract pollinators, such as bees and butterflies, making it an excellent choice for creating a lush and inviting vertical garden.

Perennial Climbers: Long-Lasting Beauty

Perennial climbers are a fantastic option for creating a long-lasting vertical garden, as they return year after year with minimal effort. Here are two popular perennial climbers that thrive on trellises:

Clematis (Clematis spp.)

Clematis is a large genus of perennial vines known for their showy flowers and diverse bloom times. With over 300 species and countless cultivars, there's a clematis for every garden. Clematis vines produce twining stems that cling to trellises using tendrils or leaf petioles. They prefer partial shade and well-draining soil but can tolerate full sun in cooler climates.

Clematis vines can grow anywhere from 6 to 30 feet tall, depending on the species and cultivar. To encourage bushier growth and more flowers, prune clematis vines according to their bloom time and growth habit. Some clematis species bloom on new wood (spring-blooming), while others bloom on old wood (summer-blooming). By selecting a mix of clematis species with different bloom times, you can create a stunning vertical garden that offers continuous color throughout the growing season.

Boston Ivy (Parthenocissus tricuspidata)

Boston ivy is a deciduous perennial vine known for its vibrant fall foliage and ability to cling to surfaces using adhesive disks on its tendrils. This vine produces small, dark green leaves that turn brilliant shades of red, orange, and purple in the fall. Boston ivy prefers full sun to partial shade and well-draining soil but is relatively adaptable to various growing conditions.

Boston ivy can grow up to 30 feet tall, making it an excellent choice for covering large trellises or creating living walls. Unlike other vines, Boston ivy does not produce tendrils but instead uses adhesive disks on its tendrils to cling to surfaces. This vine is also known for its ability to provide shade and reduce energy costs when grown on the south and west-facing walls of buildings. However, it's essential to monitor Boston ivy's growth, as it can become invasive in some regions and may require occasional pruning to prevent it from spreading too aggressively.

Creating a vertical garden with trellises offers endless possibilities for adding color, texture, and functionality to your outdoor space. By selecting the right plants for your trellis, you can create a lush, thriving garden that not only enhances your home's curb appeal but also provides habitat and food for local wildlife. So, grab your gardening gloves and start exploring the world of climbing plants – your perfect trellis garden awaits!
