Æsculus (Pavia) parviflora, blooming in July when flowering shrubs are rare, is easily grown and strikingly handsome, and yet how rarely seen! Calycanthus floridus, with its spice-scented blooms of low-toned crimson, also a late summer flower, is a fine thing in a cool, well-sheltered corner, where the sun cannot burn the flowers. The Rose Acacia (Robinia hispida), trained on a wall or house, is as beautiful as any Wistaria, and the quality of the low-toned rosy bloom of a much rarer colour. It is quite hardy, but so brittle that it needs close and careful wall training or other support. To name a few others in the same kind of category, but rather less hardy, the Sweet Bay is the noblest of evergreen bushes or small trees; the Tamarisk, with its grey plumes of foliage and summer flower-plumes of tenderest pink, is a delightful plant in our southern counties, doing especially well near the sea. Clethra alnifolia, against a wall or in the open, is a mass of flower in late summer, and the best of the Hibiscus syriacus, or Althæa frutex, the shrubbery representatives of Mallows and Hollyhocks, are autumn flowers of the best class. A bushy plant of half-woody character that may well be classed among shrubs, and that was beloved of our grandmothers, is Leycesteria formosa, a delightful thing in the later autumn. The large-fruited Euonymus (Spindle Tree) is another good thing too little grown.
DOUBLE-FLOWERED SLOE OR BLACKTHORN.
For a peaty garden there are many delightful plants in the neglected though easy-to-be-had list. One of these is the beautiful and highly fragrant Azalea occidentalis, all the better that the flowers and leaves come together and that it is later than the Ghent Azaleas. Then there are the two sweet-scented North American Bog Myrtles, Myrica cerifera and Comptonia asplenifolia, the charming little Leiophyllum buxifolium, of neatest bushy form, and the Ledum palustre, whose bruised leaves are of delightful aromatic fragrance; Vaccinium pennsylvanicum, pretty in leaf and flower and blazing scarlet in autumn, and Gaultheria Shallon, a most important sub-shrub, revelling in moist peat or any cool sandy soil.
These examples by no means exhaust the list of desirable shrubs that may be found for the slightest seeking. This brief recital of their names and qualities is only meant as a reminder that all these good things are close at hand, while many more are only waiting to be asked for.
CHAPTER II
ORNAMENTAL PLANTING IN WOODLAND
Where woodland adjoins garden ground, and the one passes into the other by an almost imperceptible gradation, a desire is often felt to let the garden influence penetrate some way into the wood by the planting within the wood of some shrubs or trees of distinctly ornamental character.
Such a desire very naturally arises—it is wild gardening with the things of larger growth; but, like all forms of wild gardening (which of all branches of gardening is the most difficult to do rightly, and needs the greatest amount of knowledge), the wishes of the planter must be tempered with extreme precaution and restraint. It does not do to plant in the wild garden things of well-known garden character. This is merely to spoil the wood, which, in many cases, is already so good that any addition would be a tasteless intrusion of something irrelevant and unsuitable.
