Orobus aurantiacus is a beautiful plant not enough grown, one of the handsomest of the Pea family, with flowers of a fine orange colour, and foliage of a healthy-looking golden-green. A striking and handsome plant in the upper part of the rockery is Othonna cheirifolia; its aspect is unusual and interesting, with its bunches of thick, blunt-edged leaves of blue-grey colouring, and large yellow daisy flowers. There is a pretty group of the large white Thrift, and near it a spreading carpet of blue Veronica and some of the splendid gentian-blue Phacelia campanularia, a valuable annual for filling any bare patches of rockery where its brilliant colouring will suit the neighbouring plants, or, best of all, in patches among dwarf ferns, where its vivid blue would be seen to great advantage.
Two wall-shrubs have been conspicuously beautiful during May; the Mexican Orange-flower (Choisya ternata) has been smothered in its white bloom, so closely resembling orange-blossom. With a slight winter protection of fir boughs it seems quite at home in our hot, dry soil, grows fast, and is very easy to propagate by layers. When cut, it lasts for more than a week in water. Piptanthus nepalensis has also made a handsome show, with its abundant yellow, pea-shaped bloom and deep-green trefoil leaves. The dark-green stems have a slight bloom on a half-polished surface, and a pale ring at each joint gives them somewhat the look of bamboos.
Now is the time to look out for the big queen wasps and to destroy as many as possible. They seem to be specially fond of the flowers of two plants, the large perennial Cornflower (Centaurea montana) and the common Cotoneaster. I have often secured a dozen in a few minutes on one or other of these plants, first knocking them down with a battledore.
Rhododendrons where the Copse and Garden meet.
Now, in the third week of May, Rhododendrons are in full bloom on the edge of the copse. The plantation was made about nine years ago, in one of the regions where lawn and garden were to join the wood. During the previous blooming season the best nurseries were visited and careful observations made of colouring, habit, and time of blooming. The space they were to fill demanded about seventy bushes, allowing an average of eight feet from plant to plant—not seventy different kinds, but, perhaps, ten of one kind, and two or three fives, and some threes, and a few single plants, always bearing in mind the ultimate intention of pictorial aspect as a whole. In choosing the plants and in arranging and disposing the groups these ideas were kept in mind: to make pleasant ways from lawn to copse; to group only in beautiful colour harmonies; to choose varieties beautiful in themselves; to plant thoroughly well, and to avoid overcrowding. Plantations of these grand shrubs are generally spoilt or ineffective, if not absolutely jarring, for want of attention to these simple rules. The choice of kinds is now so large, and the variety of colouring so extensive, that nothing can be easier than to make beautiful combinations, if intending planters will only take the small amount of preliminary trouble that is needful. Some of the clumps are of brilliant scarlet-crimson, rose and white, but out of the great choice of colours that might be so named only those are chosen that make just the colour-harmony that was intended. A large group, quite detached from this one, and more in the shade of the copse, is of the best of the lilacs, purples, and whites. When some clumps of young hollies have grown, those two groups will not be seen at the same time, except from a distance. The purple and white group is at present rather the handsomest, from the free-growing habit of the fine old kind Album elegans, which forms towering masses at the back. A detail of pictorial effect that was aimed at, and that has come out well, was devised in the expectation that the purple groups would look richer in the shade, and the crimson ones in the sun. This arrangement has answered admirably. Before planting, the ground, of the poorest quality possible, was deeply trenched, and the Rhododendrons were planted in wide holes filled with peat, and finished with a comfortable "mulch," or surface-covering of farmyard manure. From this a supply of grateful nutriment was gradually washed in to the roots. This beneficial surface-dressing was renewed every year for two years after planting, and even longer in the case of the slower growing kinds. No plant better repays care during its early years. Broad grass paths leading from the lawn at several points pass among the clumps, and are continued through the upper parts of the copse, passing through zones of different trees; first a good stretch of birch and holly, then of Spanish chestnut, next of oak, and finally of Scotch fir, with a sprinkling of birch and mountain ash, all with an undergrowth of heath and whortleberry and bracken. Thirty years ago it was all a wood of old Scotch fir. This was cut at its best marketable maturity, and the present young wood is made of what came up self-sown. This natural wild growth was thick enough to allow of vigorous cutting out, and the preponderance of firs in the upper part and of birch in the lower suggested that these were the kinds that should predominate in their respective places.
