Bignonia, evergreen plant: characteristics
All plants that belonged to the genus Bignonia have become part of the larger genus Campsis and there are several that we can easily find in our part, in public and private gardens. It is a plant that enjoys good health and that grows vigorous and florid, withstands the cold, except in some of its more cold varieties.
The leaves of the Bignonia they are lanceolate, light green in color, with a serrated profile. In winter they fall and then come back and in spring colorful flowers appear. Recently some special varieties of Bignonia have been selected that give to those who grow them - something quite easy to do - very large and brightly colored flowers. My favorite is the flaming red.
There Capreolata is a variety of Bignonia which grows very quickly and quickly reaches 10 meters in height, is much loved by bees. The leaves are oval, oblong and toothed like those of the other varieties, always green in color, very shiny during spring and summer, while they turn red in autumn.
There Capreolata is a plant that climbs with its suckers, obviously produces flowers like any of its genus companions, its are red-orange color and grouped in "spikelets". Each flower has a 5 cm corolla that ends in five enlarged lobes. There Bignonia Capreolata it is widespread in Italy, in the central and southern regions of the country where the warm climate allows it to grow easily even outdoors, while further north it is better to keep it in greenhouses.
Most of the varieties of this plant are climbers, the most common being the campsis radicans and perhaps we have seen it in many gardens even in our area without ever knowing its name. There Bignonia is of American origin and its relentless and cunning attachment to any surface is well known, but the large flowers it produces, orange, yellow and red, but not only.
Bignonia Campsis Grandiflora
Another species very frequently present in the nurseries and gardens of our country is the Campsis grandiflora, originally from Japan and Asia. It is not very adept at climbing, it prefers to be helped with supports and tutors, very often it is therefore preferred to grow it in pots or in the form of a garden shrub.
It does not climb but makes magnificent flowers that have nothing to envy to those of the others. There are also some subspecies including the Flava variety, with yellow flowers, and Tagliabuana, with very large, red flowers. This Bignonia it is one of the cold ones, therefore it should be kept in areas sheltered from the wind and never at temperatures below -10 degrees.

Some varieties prefer to be comfortable in pots rather than climb, in any case they prefer a porous and very well drained and light soil, but also the common garden soil. At 50 euros you can buy them online potted Bignonia seedlings already rooted, at least 10 cm high to be regenerated in water as soon as they arrive per package.
The flower of the Bignonia it appears in early summer and remains until autumn. It is large and in the shape of a trumpet, its colors are shades of orange, from the palest that resembles a deep yellow, to the most intense that can also be defined as red, The flowers are always gathered in bunches of six or even ten or twelve.
Returning to the trumpet shape, is very similar to that of the surfinia and of petunia: the corolla is made up of five petals that wrap around forming a sort of thin cone while towards their ends they widen creating a kind of trumpet.
