Of the fully thirteen hundred species and varieties of Trees and Shrubs enumerated, all may be depended upon as being hardy in some part of the country. Several of them, and particularly those introduced from China and Japan, have not before been included in a book of this character. Trials for the special purpose of testing the hardiness of the more tender kinds have been instituted and carried out in several favoured parts of England and Ireland. A.D.W. HOLLYDALE, WOBURN. PREFACE TO SECOND AND CHEAP EDITION, 1897. The First Edition of Hardy Ornamental Flowering Trees and Shrubs having been sold out, it has been considered desirable to run off a second and cheap edition on exactly similar lines to the first, and previous to the more elaborate illustrated edition which is now in hand. A.D.W. BOXMOOR, HERTS, 1897. HARDY ORNAMENTAL FLOWERING TREES & SHRUBS. ABELIA. ABELIA CHINENSIS (_syn A. rupestris_).--The Rock Abelia China, 1844. This is a neat, twiggy shrub, growing from 2 ft. to 3 ft. high, with slender shoots, and very pleasing, shining green serrated leaves. The tubular, sweet-scented flowers are produced in clusters at the ends of the shoots, even the smallest, and are of a very delicate shade of pink--indeed, almost white. It makes an excellent wall plant, but by no means refuses to grow and flower freely without either shelter or protection, provided a fairly rich and well drained soil is provided. From August to October is the flowering period of this handsome deciduous shrub. This is the only really hardy species of the genus, for though the rosy-purple flowered A. floribunda from Mexico has stood for several years uninjured in the South of England, it is not to be relied upon. Both species are readily propagated from cuttings. A. TRIFLORA.--Himalayan regions, 1847. A half-hardy and beautiful species with small lanceolate, entire leaves, and pretty star-shaped flowers that are white and flushed with pink. The long, narrow, and hairy calyx-lobes give a light and feathery appearance to the flowers, which are produced continuously from May to November. It does best as a wall plant, and several beautiful examples may be seen in and around London, as also at Exeter, and in the South of Ireland. ADENOCARPUS. ADENOCARPUS DECORTICANS (_syn A. Boissieri_).--Spain, 1883. This little known hardy shrub, a native of the Sierra Nevada mountains, in Spain, is one of great beauty, and well worthy of extended culture. The flowers are produced abundantly, and are of a bright yellow colour, resembling those of our common Broom, to which family it is nearly allied. Peaty soil suits it well, and repeated trials have clearly proved that it is hardy, at least in the South of England. AESCULUS. AESCULUS CALIFORNICA (_syn Pavia californica_).--California. This is one of the handsomest species, of low, spreading habit, and blooming freely about midsummer.
