No other plant is perhaps more evocative of the Mediterranean regions than this. Although 18 species are from South America, it is B. glabra and its varieties which are most commonly planted. The long, scrambling, thorny stems soon cover a wall or fence and when crowded with their deep rose, purple, red or orange flower-clusters, the effect is both stun-ning and exotic. They are sometimes trained into trees, which they climb with great speed and tumble their glorious stems from the highest branches. The flowers are produced over many months of summer and autumn, mak-ing this one of the most popular and reliable of all subtropical climbers.
