The trumpet vine (Campsis radicans), which is also called hummingbird vine, is a strong plant that has thick vines and lots of pretty trumpet-shaped flowers from midsummer to the first frost in the fall. If you have access to a healthy plant, you can easily start a new trumpet vine from cuttings. Read on to learn the basics of this trumpet plant propagation.
Trumpet vines are fast-growing climbers that produce stunning tubular flowers. If you already have an established plant, propagating trumpet vine is an easy way to get more of these beauties growing in your garden. This article covers the top techniques for propagating trumpet vine yourself to create vibrant new additions.
Why Propagate Trumpet Vine?
Trumpet vines (Campsis radicans) are prized for their:
- Orange-red tubular flowers mid to late summer
- Vigorous growth up to 40 feet high
- Adaptability to various soils and light levels
However, some gardeners are hesitant about planting trumpet vine, as it can spread aggressively through suckering roots Propagating from an existing plant allows you to control where new trumpet vines pop up. It also yields mature vines more quickly than starting from seed
Through propagation, you can:
- Share vines with gardening friends and neighbors
- Replace aging vines
- Fill blank fences or arbors with quick growth
- Increase flowering for more summer color
When to Propagate Trumpet Vines
Early spring before new growth begins is the best time to propagate trumpet vines This gives new plants time to establish roots before summer. Fall is another option, but spring-started vines gain more growth in the first season
How to Propagate Trumpet Vine
Trumpet vine can be propagated through:
- Suckers and root cuttings
- Stem cuttings
- Layering
- Seeds
Here are more details on each method:
Propagating from Suckers
The easiest way to propagate trumpet vine is by digging up one of the suckering runners spreading from the main plant. These offshoots have their own root systems that allow them to be replanted and grow independently.
- Use a shovel to carefully dig up sucker shoots 3-4 inches below the soil in early spring.
- Replant runners at the same depth, water well and tamp soil.
- Within a few weeks, shoots will leaf out as they establish.
Propagating from Root Cuttings
You can also take 3-4 inch sections of trumpet vine roots in early spring.
- Use a shovel to expose root systems and trace back to the parent vine.
- Take several 3-4 inch sections, keeping the original orientation noted.
- Replant slightly buried in soil and water well. New shoots will emerge at the cut ends as they root.
Propagating from Stem Cuttings
Mid-summer stem cuttings can be rooted in potting mix:
- Take 6 inch cuttings from green stem tips after blooming finishes.
- Trim the bottom leaves and dip cut end in rooting hormone (optional).
- Plant in sterile potting mix, water, and place in partial shade.
- Rooting takes 1-2 months before cuttings can be transplanted.
Propagating from Layering
Layering involves encouraging roots to form on part of the stem while still attached to the parent plant.
- In spring, choose a low stem branch and wound the bark with a knife.
- Bend the branch to the ground and bury a few inches of the wounded area in soil.
- Hold it in place with a wire or rocks. Keep moist.
- Once roots form in a few months, cut from the parent and transplant.
Propagating from Seeds
Though slower, trumpet vines can be started from seed either indoors or directly outside:
- Collect seeds from mature pods in fall and store until spring.
- Sow seeds 1⁄4 inch deep either indoors 6-8 weeks before last frost, or outside after danger of frost.
- Germination takes 10-20 days. Grow on for 8-12 weeks before transplanting seedlings.

How to Root Trumpet Vine Cuttings
Propagating trumpet vine cuttings can be done any time of year, as the vines root readily. However, starting trumpet vine cuttings tends to be most effective in spring when stems are tender and flexible. Prepare a planting container ahead of time. For one or two cuttings, a small pot will do. If you want to start more than two, use a larger pot or a planting tray. Be sure the container has at least one drainage hole. Fill the container with clean, coarse sand. Fill the pot with water and let it drain until the sand is evenly wet but not dripping. Cut a 4 to 6-inch (10 to 15 cm. ) stem with several sets of leaves. Make the cutting at an angle, using a sterile knife or razor blade. Take off the bottom leaves, leaving one or two sets of leaves on top of the cutting. Dip the bottom of the stem in rooting hormone, then plant the stem in the moist potting mix. Place the container in bright but indirect light and normal room temperatures. Water as needed to keep the potting mix consistently moist, but never soggy. After about a month, tug gently on the cutting to check for roots. If the cutting has rooted, you’ll feel a slight resistance to your tug. If the cutting offers no resistance, wait another month or so, and then try again. When the cutting has successfully rooted, you can transplant it to its permanent spot in the garden. If it’s cold outside or you’re not ready to plant your trumpet vine yet, move it to a 6-inch (15 cm) pot. ) pot with regular potting soil from the store and let it grow until you’re ready to plant it outside.
