      As may be seen by the illustration (Fig. 14), it is in the way of a climbing bean. The flowers are purple and borne in small clusters from the axils of the leaves, and, of course, as indicated by the order to which it belongs, they are like pea flowers; they are produced a long time in succession, providing the frosts do not occur; they have the scent of violets. The leaves are distantly produced on fine wiry stems, which grow to the length of 12ft.; they are pinnate, the leaflets being of various sizes, oval, smooth, and of a dark shining green colour.

      The roots are not only peculiar in the way already mentioned, but the tubers have the appearance of being strung together by their ends. They are edible, and where they grow wild they are called "ground nuts." From the description given it will be easy to decide how and where it should be planted.

      There should be provision made for its twining habit, and it may have the liberty of mixing its foliage with that of less beautiful things during autumn, such, for instance, as the bare Jasmine nudiflora; its spare but effective leaves and flowers will do little or no harm to such trees, and after the frosts come the jasmine will be clear again. It may also be grown with happy results as shown in the illustration, needing only a well-secured twiggy bush. Cut as sprays it is very serviceable for hanging or twining purposes.

      It most enjoys a light soil, also a sunny situation. Sometimes it has been found slow at starting into growth when newly planted; this, however, can hardly be the case with newly lifted tubers. I may add that it is no uncommon thing for these to be out of the ground for weeks and months together, when they not only become hard and woody, but when suddenly brought in contact with the damp earth rot overtakes them. There is no difficulty whatever with fresh tubers, which may be lifted after the tops have died off. Beyond securing fresh roots, there is nothing special about the culture of this desirable climber.

      Flowering period, August to October.

      Arabis Lucida

      This member of a well-known family of early spring flowers is desirable, for its neat habit and verdancy. There is not a particle of sere foliage to be seen, and it has, moreover, a glossy appearance, whence the specific name. The flowers are not of much effect, though, from their earliness, not without value; they are in the way of the flowers of the more common species, A. alpina, but less in size; they are also more straggling in the raceme; these two features render it inferior as a flower; the stalks are 3in. to 6in. high. The leaves are arranged in lax flattened rosettes, are 1in. to 3in. long, somewhat spathulate, notched, fleshy, of a very dark green colour, and shining. The habit is dense and spreading, established tufts having a fresh effect. Though an Hungarian species, it can hardly have a more happy home in its habitat than in our climate. Where verdant dwarf subjects are in request, either for edgings, borders, or rockwork, this is to be commended as one of the most reliable, both for effect and vigour. In the last-named situation it proves useful all the year round, but care should be taken that it does not overgrow less rampant rock plants.

       A. l. variegata is a variety with finely-marked leaves. The bloom resembles that of the type, but is rather weaker. It is better to remove the flowers of this kind, as then the rather slow habit of growth is much improved, as also is the colour of the foliage. The leaves being more serviceable and effective than the bloom, the uses should be made of it accordingly. They are broadly edged with yellow, the green being lighter than that of the type, but equally bright; the ends of the leaves are curled backwards, but, with the exception of being a little smaller, they are similar in shape to the parent form. This is a gem for rockwork, and, if it did not belong to a rather ordinary race of plants, it would, perhaps, be more often seen in choice collections. This, however, does not alter its worth. Seen in crevices of dark stone on rockwork, or in bold tufts near the walks, or planted with judgment near other dwarf foliaged subjects, it ever proves attractive. It is much less rampant, and, perhaps, less hardy than the type. It has only been during the recent very severe winters, however, that it has been killed. The Arabis is easily propagated by slips or rootlets, which should be taken after flowering. The variegated form is better for being so propagated every year. If bold patches are desired, they should be formed by planting a number together, 3in. or 4in. apart.

      Flowering period, February to June.

      Aralia Sieboldi

      The present subject (see Fig. 15)—beautiful, hardy, and evergreen—is a species of recent introduction; still, it has already become well known and distributed, so much so that it scarcely needs description; but there are facts in reference to it which would seem to be less known. It is seldom seen in the open garden, and many amateurs, who otherwise are well acquainted with it, when they see it fresh and glossy in the open garden in the earliest months of the year, ask, "Is it really hardy?" Not only is such the case, but the foliage, and especially the deep green colour, are rarely so fine when the specimens have indoor treatment, and, on this account, the shrub is eminently suitable for notice here.

      Fig. 15. Aralia Sieboldi.

      (One-tenth natural size.)

      The order Araliaceæ is nearly related to Umbelliferæ, from which fact an idea may be had of the kind and arrangement of the flowers. Many of the genera of the order Araliaceæ are little known; perhaps the genus Hedera (ivy) is the only one that is popular, and it so happens to immediately follow the genus Aralia. To remember this will further assist in gleaning an idea of the form of blossom, as that of ivy is well known. Aralia Sieboldi, however, seldom flowers in this climate, either in or out of doors. When it does, the white flowers are not of much value; they are small, like ivy blossom in form, but more spread in the arrangement. There are five sepals, five petals, five styles, and five cells in the berries. The flowers are produced on specimens 2ft. to 5ft. high during winter, when favourable. The leaves, when well grown, are the main feature of the shrub, and are 12in. or more across. This size is not usual, but a leaf now before me, and taken from an outside specimen, measures over a foot, with a stout round stalk, 13in. long; the form of leaf is fan-shaped, having generally seven lobes, each supported by a strong mid-rib; the lobes are formed by divisions rather more than half the diameter of the leaf; they are slightly distant, broadly lance-shaped, waved at the edges, toothed near the ends, the teeth being somewhat spiny; the substance is very stout and leather-like to the touch; the upper surface is a dark shining bronzy-green, beautifully netted or veined; the under surface is a pale green, and richly ornamented by the risen mid-ribs and nerves of the whole leaf; the leaf-stalks are thick, round, bending downwards, and 6in. to 18in. long, springing from the half woody stem.

      The habit of the shrub is bushy, somewhat spreading, causing the specimens to have a fine effect from their roundness, the leaf arrangement also being perfect. Without doubt this is one of the most distinct and charming evergreens for the ornamental garden, sub-tropical in appearance, and only inferior to palms as regards size; it is effective anywhere. It need not be stated that as a vase or table decoration it ranks with the best for effect and service, as it is already well-known as such. In planting this subject outside, young but well-rooted examples should be selected and gradually hardened off. At the latter end of May they should be turned out of the pots into a rich but sandy loam. The position should be sunny, and sheltered from the north. Some have advised that it should be grown under trees, but I have proved that when so treated the less ripened foliage has suffered with frost, whilst the specimens fully exposed to the sun have not suffered in the least; they would droop СКАЧАТЬ
