The name of this genus, Bignonia, was established 
by Tournefort, in honour of the Abbe Bignon. Ra- 
dicans, from the Latin radicatus, rooted ; in allusion 
to the habit of this species of Bignonia, in producing 
fibrous appendages, similar to roots, from the joints 
of its stems. Thus, as a climber, is this plant sup- 
ported, by its growth up the trunks of trees, to a 
great height. Miller says, to the height of forty or 
fifty feet. When trained up brick walls, these fibres 
will generally insinuate themselves even into the 
mortar joints of the building. 
The splendid panicles of flowers produced by this 
fine climbing shrub, are particularly attractive ; and 
where a wall of south or south-east aspect offers it- 
self, for the support of such a plant, this should con- 
stitute one of its embellishments. 
It is usually propagated by layers, which should 
be taken off in about twelve months from the time of 
their being put down. It will be advisable, early in 
every spring, to cut back the stems very consider- 
ably, particularly those which are of rather weak 
growth ; by which treatment, luxuriant young shoots 
will be produced, that will flower freely.
