The following list of tender shrubs and trees growing in the gardens of the south-west cannot claim to be an exhaustive one, since it contains only such as have been personally noticed in good health during rambles along the southern coast-line of Cornwall and Devon, and, where no lengthened inspection is possible, it is obvious that certain species and varieties must be overlooked. Incomplete, however, as it doubtless is, it should give an idea of the climatic advantages enjoyed by the district in question.
Many of the subjects mentioned are growing in Tresco Abbey gardens, Isles of Scilly, but most of these are also found in mainland gardens as well. Where any have been met with at Tresco only, the fact is noted, but these may also be present on the mainland.
The soil of the Scillies, which is composed apparently of peat and disintegrated granite, and is almost identical with much of that around Penzance, is admirably adapted for hard-wooded Australian, New Zealand, and Chilian shrubs and trees, and almost all the species and genera enumerated would be best suited by a compost in which peat and leaf-mould and granite sand formed the chief proportion, although it must be allowed that some alluded to have been found to succeed equally well in sandy loam. Porosity in the soil is indispensable, for, in this district, where the winter rains are often exceptionally heavy, unless the water percolates rapidly through the ground, stagnant moisture collects around the roots, a condition which is absolutely fatal to success. The advantages of the Cornish granite sand are gradually being appreciated. Mr. Fitzherbert writes, "I was told the other day by an acquaintance that since he had imported it by the truck-load to his Sussex garden he was able to grow many things successfully that he had before failed with."
ABELIA FLORIBUNDA.--Mexico. A beautiful evergreen shrub, bearing clusters of drooping pink flowers about 3 inches in length. Requires a sunny and sheltered site. Finest specimen 6 feet. Several gardens.
ABUTILON VEXILLARIUM.--Rio Grande. A handsome evergreen species generally grown against a wall. It throws up long, slender, arching shoots from 6 to 8 feet in length, studded with pendulous ball-shaped flowers with crimson sepals, yellow petals, and dark-brown stamens which are very striking and often remain in bloom for six months. Common. _A. vitifolium_--Chili. A most ornamental evergreen shrub of which there are two forms, one bearing lavender flowers, the other white. In exceptional cases it attains a height of 20 feet, and when covered with its large blossoms, which are about 3 inches in diameter, and feathered to the ground with foliage, it presents a lovely picture. Large specimens form pyramids of bloom, and in some gardens numbers of these are to be found. Wall protection unnecessary.
