CHAPTER XXV

TENDER WALL PLANTS IN THE SOUTH-WEST

The notes on tender shrubs and trees grown in the south-west are
fittingly supplemented by a passing reference to plants used for
covering walls, mostly of climbing habit, but a few of shrubby growth.

BIGNONIA.--_B. (Tecoma) radicans_ is a hardy climber, and _B.
capreolata_ may also be considered so. Other members of the family grown
in the open are _B. capensis_, Cape of Good Hope, orange; _B. Cherere_,
Guiana, orange scarlet; and _B. speciosa_, Uruguay, pink. Greenway on
the Dart.

BERBERIDOPSIS CORALLINA.--Chili. Drooping crimson flowers borne in
racemes in the autumn. This evergreen plant does best in peat or
leaf-mould in a partially shaded position. Common.

BOUGAINVILLEA GLABRA.--Brazil. This climber cannot be considered a
success in the open in the south-west, but in two gardens it has been
grown and flowers, but in neither case has it exhibited a tithe of the
freedom of growth displayed by it under glass.

BUCKLANDIA POPULNEA.--Himalayas. A handsome evergreen foliage plant,
said to grow to a height of 100 feet in its native habitat. Its large
heart-shaped leaves are tinted with bronze and maroon. Tregothnan.

CALLICARPA PURPUREA.--India. An evergreen shrub bearing small
inconspicuous flowers, followed by violet-coloured berries. Trewidden,
Penzance.

CASSIA CORYMBOSA.--Buenos Ayres. A rambling shrub, almost invariably
