Other name:Bignone tagliabuana
A cross between virginia bignone (Campsis radicans) and campsis grandiflora (Campsis grandiflora), Campsis x tagliabueana is perhaps the most widespread bignone in gardens. This hybrid has given rise to numerous cultivars with yellow, orange or red flowers.
How to recognize Campsis x tagliabueana bignone?
The Campsis x tagliabueana bignone is a shrub with a sarmentose stump. It can reach 10 m in all directions. Its flexible branches are equipped with aerial roots. These act as spikes or tendrils, enabling the plant to climb almost any surface.
The pinnate leaves have up to 11 oval leaflets. Bright green, with paler undersides and pronounced veins.
Campsis x tagliabueana is not grown for its deciduous foliage, but for its funnel-shaped flowers. Red, orange or yellow, they bloom in summer, attracting butterflies and pollinators.
They then give way to dehiscent brown pods. These contain the seeds, which are then spread by the wind.
Which variety of Campsis × tagliabueana should I plant in my garden?
There are several varieties of Campsis x tagliabueana. They differ mainly in flower color and shape:
- 'Indian Summer' (or Kundian): a variety with short, yellow flowers, less vigorous than the others;
- Madame Galen': an old French variety, with salmon-orange flowers;
- dancing Flames': a cultivar not exceeding 3 m in all directions, with orange-red flowers
- summer Jazz Gold': a bignone with short, wide-open yellow flowers that reaches 3 m at best.
Is Campsis x tagliabueana bignone toxic?
Yes, bignone is a toxic plant. Ingested, it causes digestive problems, particularly in domestic animals. Its sap can also cause irritation if it comes into contact with the skin. Make sure your dog or cat doesn't nibble your plant, and wear gloves when pruning and repotting.
Our care tips
Is your Campsis × tagliabueana wearing out and flowering less abundantly? Cut back the branches to 30 or 50 cm to give it a new lease of life.
Watering
Campsis × tagliabueana Trumpet Vines They like to keep the potting mix moist, but not soggy. Water when the soil is dry on the surface (about two to three centimeters deep).
Water the substrate with non-hard water—such as rainwater—at room temperature.
Let the water drain out through the drainage holes before returning the plant to its place. Empty any standing water from the saucer or planter. It may cause the roots to rot.
Repotting
Plant your Campsis × tagliabueana in a pot with drainage holes. You can add a layer of clay pellets or gravel to optimize drainage.
If you plan to use a trellis or stake, you can place it in the pot now.
Line the bottom of your container with a well-draining substrate. You can use all-purpose potting soil or garden soil mixed with a few handfuls of sand.
Plant your Campsis × tagliabueana. If you want your plant to climb a wall or tree, position the root ball toward the support. Add more substrate, but stop a few centimeters short of the edge to create a watering basin.
Guide the vines toward their support. Firm the soil and water generously to remove air pockets and encourage root growth.
Fertilization
You can stimulate the growth of your plant during its growth phase, in spring and summer, with fertilizer.
Fertilize your Bignone Campsis × tagliabueana every month. Use a flowering plant fertilizer to stimulate flowering.
You can stimulate the growth of your plant during its growth phase, in spring and summer, with fertilizer.
Put compost at the foot of your Bignone Campsis × tagliabueana to stimulate its growth.
Prune
Your Campsis × tagliabueana is a vigorous plant. You don't have to prune it, but doing so will prevent the plant from becoming invasive.
Identify the main branches that form the structure against the wall, pergola, or support. You don't need to prune them unless you want to rebalance the plant's shape.
However, remove:
- Dead or weak twigs;
- Branches that cross over in the center and block light;
- Stems growing in the wrong direction;
- Suckers at the base, if you want to control growth.
Your Campsis × tagliabueana blooms on this year's new growth. You can therefore prune last year's side shoots (which have already bloomed) back to the second or third bud without compromising flowering.
Always use a clean, sharp tool to promote healing and prevent the spread of disease.
Planting
Once the last spring frosts have passed, you can plant.
Soak the root ball of your Campsis × tagliabueana to rehydrate it. Leave it in the water until there are no more air bubbles.
Dig a hole 40 cm deep. You can place clay balls or gravel at the bottom for better drainage.
Plant your Campsis × tagliabueana. The top of the root ball should be level with the ground. Fill in the hole with garden soil. You can add a little sand if your soil is heavy.
Guide the stems onto their support to show them the way.
Mulch the soil to keep the base of the plant cool. Firm the soil and water it to encourage root growth.
Taking cuttings
Propagation by cuttings is carried out during the strong growth phase, generally in spring and early summer.
Locate a healthy, flowerless stem. It should be semi-woody, but still flexible.
Cut a ten- to fifteen-centimetre section just below a node. Use clean, sharp secateurs to facilitate healing.
Remove the lower leaves and keep only the upper pair.
Plant your cutting in a pierced pot lined with potting soil for seedlings and plantations. Spray the substrate with non-calcareous water.
The graft takes better in a stifled environment. Cover the plant with a translucent plastic bag or cloche.
Place your young plant in a bright room where the temperature is between 20 and 25°.
The appearance of new leaves indicates that your cutting is taking root.
Frequently asked questions
What exposure for bignone?
The trumpet vine thrives in sunny, warm exposure to produce abundant blooms all summer long. Plant it preferably against a south- or west-facing wall, sheltered from cold winds. It tolerates partial shade but will often bloom less profusely. A bright location also promotes rapid and vigorous growth.
Does bignone fear frost?
The trumpet vine generally withstands cold well once established. Depending on the variety, it can tolerate temperatures around -10 to -15 °C. Young plants, however, remain more sensitive to severe frosts. In winter, mulching around the base protects the roots. In harsh climates, choose a sheltered, sunny location.
