The Trumpet vine or trumpet creeper, Campsis in Latin, surprises many a passer-by around the corners of old streets in our villages. This vigorous liana with flowers that are generally orange or yellow in trumpet shape adorns façades, gates, and arbors. It has become a popular plant, in a way naturalized. There are also other beautiful Trumpet vines like the Podranea or pink Trumpet vine to dress façades and arbors.

You live in the Mediterranean region.
The Mediterranean shores offer you a mild winter where frosts are exceptional and a summer with abundant sunshine. The Pandorea jasminoides ‘Rosea’ will delight you with its large trumpet-shaped pink flowers in any deep soil. Its vegetation is destroyed at 0 °C, but a well-established stump protected by a thick mulch can survive short frosts down to -5 °C.
The Podranea ricasoliana ‘Comtesse Sarah’, pink Bignonia or Ricasoli Bignonia, sometimes called orchid liana, is another species from the Bignoniaceae family native to South Africa and Zimbabwe. The Bignonia ‘Comtesse Sarah’ lacks a support system, so it will need to be trained. Fast-growing, it can reach 7 to 9 m in all directions, but will not exceed 3 to 4 m in a pot. The aerial vegetation is destroyed at -3 °C, which explains why the foliage is most often deciduous in our climates. The flowering period is remarkably long. It begins in late June or early July and ends in October, provided the weather remains mild. It requires warmth and sunshine to flower well. This is an excellent liana for a southern garden. Elsewhere, it can be grown easily in a large container, to be stored away in winter. All aerial parts of the plant are destroyed when the temperature drops below -5 °C, but it will regrow from the stump in spring, albeit quite late.
