Bignonias are handsome climbers, bearing large panicles of 

 bell-shaped flowers. Propagate by cuttings of the young side- 

 shoots in summer in the cool pit. Grow in rich loam, sand, 

 and a little peat. 

 They flower on

 be pruned directly 

 after flowering,

 summer to induce 

 the formation of 

 spurs. Sorts : B. 

 capreolata and 

 B. speciosa, flower-

 venusta, flowering 

 in late summer.
