Bignone with deciduous foliage is a climbing plant that is wonderful for covering a wall or a pergola, especially since its growth is very fast (about 1 m per year). It clings alone on its supports thanks to its aerial roots, which act as crampons.
Its opposite, pinnate leaves are cut into toothed leaflets, often of a rather dark green. Its beautiful flowers in trumpet or funnel of yellow, orange or almost red depending on the variety, are abundant and last all summer: they can measure about ten centimeters long and are grouped in cymes or terminal panicles. As for its hardiness, it is very real since it supports -15° C in general.

Ideal soil and exposure for planting a bignone in the garden
The bignone is a climber of full sun, which needs a cool, neutral soil, with a normal humidity. It supports a limestone soil. It can not withstand cold winds or drafts.
Date of planting and cuttings of bignones
The bignone multiplies by sowing under cold frame in autumn but it is necessary to be patient. The cutting is done in the spring, but you can prefer the layering, easier: take a branch without flowers but with aerial roots (crampons) and lay there in the ground in early spring, to recover in the fall.
For the planting of the bignone, spring is the best season.
Board of Care and Culture of Virginia Jasmine
Shoot the shoots in the early years, as long as the plant does not do it alone. Have a mulch on the foot in case of hot weather to keep moisture. In March, cut the bignone.
Bring an organic fertilizer in late autumn (compost, manure...) to promote flowering because the plant needs a rich soil.
Diseases, pests and parasites of bignones
Mealybugs, white flies and powdery mildew are the main concerns that the bignone may encounter.
Location and favorable association of the bignone
The bignone is not grown in pots. It is intended to dress a fence, a trellis, a gate, a porch or cover a wall. It can also mingle with ivy because it will keep him, his foliage, during the winter.
Varieties of bignones recommended for a plantation in the garden
There are only two species: Campsis grandiflora, the big-horned bignone or Chinese bignone with its flowers in wide funnel with spreading lobes, dark orange to red, but which offers little clinging crampons, and then Campsis radicans, Virginia jasmine with flowers in tubular trumpets.
Many varieties have been developed as Campsis radicans 'Flava', with yellow flowers, Campsis radicans 'Stromboli', more compact with blood red flowers, Campsis radicans 'Atropurpurea', with purple red flowers...
