Best Plants for Trellises: Vertical Gardening Guide

When it comes to vertical gardening, trellises are an excellent way to maximize your space and create a stunning visual impact. But with so many plant options, choosing the right ones for your trellis can be overwhelming. Let's explore some of the best plants to plant on a trellis, categorized by their growth habits and care requirements.

Trellises provide support for plants that vine, climb, or trail. They can be made from various materials like wood, metal, or plastic, and can be freestanding or attached to walls. By choosing the right plants, you can create a lush, green oasis that not only looks beautiful but also provides habitat for pollinators and other beneficial creatures.

Annual Vines for Quick Color

Annual vines are a great choice for adding quick color and coverage to your trellis. They germinate quickly, grow rapidly, and provide vibrant blooms throughout the growing season before dying back in the fall.

Here are two popular annual vines to consider:

Morning Glories (Ipomoea purpurea)

Morning glories are classic annual vines 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, and white. Morning glories are easy to grow from seed and can quickly cover a trellis with their heart-shaped leaves and beautiful flowers.

To grow morning glories, sow seeds directly in the soil at the base of your trellis after the last spring frost. Keep the soil consistently moist until germination occurs, usually within 10-20 days. Morning glories prefer full sun and well-draining soil. Once established, they require minimal care and will self-seed readily, ensuring a continuous supply of plants year after year.

Black-Eyed Susan Vine (Thunbergia alata)

Black-eyed Susan vine is another popular annual vine that produces clusters of yellow, orange, or white trumpet-shaped flowers with dark centers. Its glossy, heart-shaped leaves add texture and contrast to the trellis. This vine is a bit more tender than morning glories and prefers warmer climates but can be grown as an annual in cooler regions.

Sow black-eyed Susan vine seeds indoors 6-8 weeks before the last spring frost or directly in the soil after the last frost. They germinate quickly and grow rapidly, producing an abundance of flowers from summer to fall. Black-eyed Susan vine prefers full sun to partial shade and well-draining soil. Keep the soil consistently moist, and provide some support as the vine grows, as it can become top-heavy.

Perennial Vines for Long-Term Beauty

Perennial vines are an excellent choice for creating a long-lasting, low-maintenance vertical garden. They return year after year, providing structure and beauty to your trellis. Here are two perennial vines to consider:

Clematis (Clematis spp.)

Clematis is a large genus of perennial vines known for their stunning flowers that bloom in various shapes, sizes, and colors. Many clematis varieties are vigorous growers that can quickly cover a trellis with their lush foliage and showy blooms. Clematis is a versatile plant that can be grown in a variety of soil types and prefers full sun to partial shade.

When choosing a clematis for your trellis, consider the plant's growth habit and bloom time. Some varieties bloom in early spring, while others bloom in summer or fall. Popular clematis choices for trellises include 'Jackmanii' (violet-purple flowers), 'Nelly Moser' (rose-pink flowers with white stripes), and 'Henryi' (small, white, star-shaped flowers). Plant clematis in well-draining soil and provide support as they grow, as some varieties can become quite large.

Boston Ivy (Parthenocissus tricuspidata)

Boston ivy is a hardy, deciduous vine that provides stunning fall color and attractive glossy green foliage throughout the growing season. In autumn, its leaves turn brilliant shades of red, orange, and purple, making it a popular choice for trellises and walls. Boston ivy is easy to grow and can tolerate a wide range of soil conditions, preferring full sun to partial shade.

Plant Boston ivy at the base of your trellis, and as it grows, it will cling to the structure using tendrils. Boston ivy is a vigorous grower, so it's essential to prune it annually to control its size and shape. In late fall or early spring, cut back the vine to the desired length, and remove any dead or damaged growth. Boston ivy is an excellent choice for providing year-round interest and color to your trellis.

Incorporating the right plants on your trellis can transform your outdoor space into a lush, vertical garden that not only looks beautiful but also supports local wildlife. By selecting a mix of annual and perennial vines, you can create a dynamic and ever-changing display that will bring joy and inspiration throughout the growing season. So go ahead, embrace the vertical, and let your trellis become a canvas for your green thumb creativity!
