RHAPITHAMNUS CYANOCARPUS.--Chili. An evergreen tree, bearing pale-blue flowers, followed by violet-blue berries. A fine specimen 20 feet in height is at Menabilly.
RUBUS AUSTRALIS.--A Bramble, the only form of which is worth growing, and that merely as a curiosity, is a practically leafless one. The leaves are indeed there, but they consist merely of three midribs armed with curved spines, and terminated by leaflets less than an inch in length of an inch in breadth. A large plant at Bishop's Teignton has smothered a Euonymus bush, and climbed into an adjacent Fir.
SENECIO.--Many of the newer evergreen exotic species, such as _S. Grayii_, _S. Fosterii_, _S. Heretieri_, and others are grown, while in Rosehill garden is a fifty-year-old plant of the Mexican _S. Petasitis_, 8 feet in height.
SOLANUM CRISPUM.--Chili. An evergreen flowering shrub, bearing lavender yellow-centred flowers in profusion, often reaching a height of 8 feet. Quite common.
SPARMANNIA AFRICANA.--Cape of Good Hope. African Hemp. An evergreen shrub, bearing masses of white flowers with ruby-tipped anthers; a well-known greenhouse plant. At Tresco both the single and double forms are grown, and attain a height of 10 feet. The single form is also met with in mainland gardens, where it is often in flower in February.
VERONICA HULKEANA.--New Zealand. An evergreen shrub, bearing branching panicles of pale-lilac flowers, doing best with the support and protection of a wall. To be found in many gardens.
WESTRINGIA TRIPHYLLA.--Australia. Evergreen shrub, bearing blue flowers in summer. Tregothnan.
[1] Probably all the trees and shrubs mentioned in this and the following chapter will succeed in Ireland.
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.
