Origins and peculiarities of the bignone

Native to North America, Japan and China, the bignone (bignonia capreolata) is a plant belonging to the bignonaceae family. It is a vigorous climber with pretty clusters of flowers, red or orange, in the shape of trumpets. The flamboyant flowering of the bignone is abundant and lasts all summer until the frosts. Very decorative, the bignone (campsis radicans) is often used to decorate walls, facades, trellises or fences.

The most common of the bignones is the campis radicans, also known as "Virginia jasmine". Other varieties are famous such as the Indian summer campis radicans, frequently used in pots on the balcony and appreciated for its hardiness, as well as the large flowered campis grandiflora of around 40 cm; without forgetting the bignone capreolata known as tendrils, evergreen and two-color flowers.
 

Plantation of the bignone


Rustic but sensitive to cold weather (temperatures below -10 ° C), the bignone appreciates sunny and sheltered areas to flourish. Indeed, wind and cold can cause flower buds to drop.
Due to its rapid growth (about one meter per year), it requires space around it to be able to develop. It is thus necessary to count a plant every 3 to 4 m to cover a wall or a fence.

Autumn and spring are the recommended seasons for bignone planting in the open ground. To promote recovery, mix potting soil and soil from the garden and add humus regularly.

But in general, the bignone is not very capricious as regards the nature of the soil which receives it: as long as the latter is sufficiently well drained, it can even be limestone or acid, the plant will flourish and may even endure very dry periods.
 

Maintenance of the bignone

Easy to grow, the bignone does not require any particular maintenance. Indeed, this plant clings to its support on its own, a bit like ivy, and grows there quickly.

The bignone is pruned in spring to resize the plant, if it becomes too invasive. Then remove dead or weak branches.

It is advisable to regularly water your bignone in summer, especially the first two years after planting.
 

Bignone enemies and pests

The bignone is a rather resistant plant, but which can all the same, in the event of a particularly hot and dry summer period, be prey to attacks:

  • Red spiders, which you can get rid of by rinsing the leaves abundantly (without forgetting the back of the leaves).
  • Aphids, which will not resist if you shower the plant with plenty of water.
  • Mealybugs, which will hide either on the back of the foliage, or on the stem of the bignone. To dislodge them, spray the plant with soapy water: their waxy shield will be less resistant, and you can remove them.
  • Powdery mildew, a cryptogamic disease caused by a fungus. If your bignone is affected, cut the critical branches and burn them.
