1. Star jasmine (Trachelospermum jasminoides)
For a sweet-scented wall of green, star jasmine is a firm favourite. This evergreen climber features glossy leaves and produces small white flowers with an intoxicating fragrance in spring and summer. It grows quickly once established and thrives in full sun or partial shade. Although not a true jasmine, it offers similar charm with a bit more resilience. It also behaves well in containers if you’re short on ground space.
2. Sweet pea (Lathyrus odoratus)
Sweet peas bring cheerful colour and a nostalgic, cottage-garden charm to any outdoor area. While technically an annual, they grow fast and flower profusely, making them ideal for seasonal screens or to train up obelisks and trellises. Sow them in early spring for a summer display in shades of purple, pink, white and red. The more you pick the flowers, the more they bloom.
3. Black-eyed Susan vine (Thunbergia alata)
This fast-growing annual vine offers a vibrant pop of yellow, orange or white, each with a dark centre that gives the plant its name. It’s perfect for adding a burst of colour to fences or arches, and it climbs quickly with minimal fuss. While it doesn’t tolerate frost, it grows so quickly from seed that you can enjoy a full season of coverage even in cooler climates.
4. Clematis montana
If you’re after a dramatic floral display, clematis montana is your go-to. This fast-growing perennial can quickly scale fences, pergolas or even mature trees. Its soft pink or white blooms appear in late spring and early summer, and the plant is hardy enough to return year after year with minimal maintenance. Plant it where it can climb high, and it’ll do the rest.
5. Nasturtium (Tropaeolum majus)
Not just a pretty face, nasturtiums are fast-growing, edible climbers that work well in both garden beds and containers. With their bright, cheerful blooms and trailing habit, they’ll quickly cover bare patches and are especially popular with pollinators. Plant them from seed in early spring and enjoy a long flowering season through summer.
Need-to-know tips for climbing success
- Most climbers benefit from a sturdy support system, especially in the early stages.
- Keep the soil moist but well-drained, and feed with a balanced fertiliser during the growing season.
- Prune back regularly to encourage fuller growth and keep your plants from becoming too leggy or invasive.
Whether you’re building a floral feature wall, creating privacy from neighbours or simply adding more green to your garden, fast-growing climbing plants offer a beautiful and practical solution. With the right care, you’ll be amazed how quickly your garden transforms.
