Both of the above Alliums may be grown in any odd parts which need decorating with subjects requiring little care; any kind of soil will do for them, but if planted too near the walks the flowers are liable to be cut by persons who may not be aware of their evil odour. The bulbs may be divided every three years with advantage, and may be usefully planted in lines in front of shrubs, or mixed with other strong-growing flowers, such as alkanets, lupins, and foxgloves.
Alyssum Saxatile

(One-third natural size.)
This pleasing and well-known hardy, evergreen, half-woody shrub is always a welcome flower. From its quantity of bloom all its other parts are literally smothered (see Fig. 3). When passing large pieces of it in full blow, its fragrant honey smell reminds one of summer clover fields.
Its golden yellow flowers are densely produced in panicles on procumbent stems, 12in. to 18in. long. The little flowers, from distinct notches in the petals, have a different appearance from many of the order Cruciferæ, as, unless they are well expanded, there seem to be eight instead of four petals. The leaves are inversely ovate, lanceolate, villose, and slightly toothed. A specimen will continue in good form during average weather for about three weeks. It is not only seen to most advantage on rockwork, where its prostrate stems can fall over the stones, but the dry situation is in accordance with its requirements; still, it is not at all particular, but does well in any sunny situation, in any soil that is not over moist or ill drained. It is easily and quickly propagated by cuttings in early summer.
Flowering period, April and May.
Anchusa Italica

(One-third natural size.)
A hardy herbaceous perennial of first-class merit for gardens where there is plenty of room; amongst shrubs it will not only prove worthy of the situation, but, being a ceaseless bloomer, its tall and leafy stems decked with brilliant flowers may always be relied upon for cutting purposes; and let me add, as, perhaps, many have never tried this fine but common flower in a large vase, the stems, if cut to the length of 18in., and loosely placed in an old-fashioned vase, without any other flowers, are more than ornamental—they are fine.
Its main features are seen in its bold leafy stems, furnished with large, dark blue, forget-me-not-like flowers, nearly all their length. The little white eyes of the blossoms are very telling (see Fig. 4). The flowers are held well out from the large leaves of the main stem by smaller ones (from 1in. to 8in. long), at the ends of which the buds and flowers are clustered, backed by a pair of small leaflets, like wings. Just before the buds open they are of a bright rose colour, and when the flowers fade the leafy calyx completely hides the withered parts, and other blooms take their places between the wing-like pair of leaflets; so the succession of bloom is kept up through the whole summer. The leaves of the root are very large when fully grown during summer—over a foot long—those of the stems are much less; all are lance-shaped and pointed, plain at the edges, very hairy, and of a dark green colour. The stems are numerous, upright, and, as before hinted, branched; also, like the leaves, they are covered with stiff hairs, a characteristic common to the order. Well-established plants will grow to the height of 3ft. to 5ft.
Flowering period, May to September.
Anchusa Sempervirens
This is a British species, and, as its name denotes, is evergreen; not, let me add, as a tall plant, for the stems wither or at least become very sere, only the large leaves of the root remaining fresh; and though it has many points of difference from A. Italica, such as shorter growth, darker flowers and foliage, and more oval leaves—these form the distinctions most observable. By its evergreen quality it is easily identified in winter. There is also an important difference from the axillary character of the flower stems. With these exceptions the description of A. Italica will fairly hold good for this native species.
This Alkanet has various other names, as Borago sempervirens, Buglossum s., and with old writers it, together with allied species, was much esteemed, not only for the flowers, but for its reputed medicinal properties. To those who care to grow these good old plants I would say, well enrich the soil; when so treated, the results are very different from those where the plants have been put in hungry and otherwise neglected situations; this favourable condition may be easily afforded, and will be more than repaid. Strong roots may be transplanted at any time, and propagation is more quickly carried out by division of the woody roots, which should be cut or split so that each piece has a share of bark and a crown. Just before new growth has begun, as in January, is the best time for this operation, so that there is no chance of rot from dormancy.
Flowering period, May to September.
Andromeda Tetragona
A dwarf hardy evergreen shrub, which comes to us from Lapland and North America; though a very beautiful subject for either rockwork or border, it is rarely seen. It is not one of the easiest plants to grow, which may, to some extent, account for its rarity. Still, when it can have its requirements, it not only thrives well, but its handsome form and flowers repay any extra trouble it may have given. In the culture of this, as of most plants of the order Ericaceæ, there is decidedly a right way and a wrong one, and if the species now under consideration has one or two special requirements it deserves them.

(One-half natural size.)
With me it never exceeds a height of 6in. or 7in., is much branched, and of a fine apple green colour; the flowers are small but very beautiful, bell-shaped, pendent, and springing from the leafy stems of the previous year's growth. The leaves are small as well as curious, both in form and arrangement, completely hiding their stems; their roundish grain-shaped forms are evenly arranged in four rows extending throughout the whole length of the branches (whence the name tetragona), giving them a square appearance resembling an ear of wheat, but much less stout (see Fig. 5); the little leaves, too, are frosted somewhat in the way of many of the saxifrages. It is next to impossible to describe this pretty shrub; fortunately, the cut will convey a proper idea at a glance. All who possess more select collections of hardy plants and shrubs should not fail to include this; it is fit for any collection of fifty choice species.
I struggled long before finding out the right treatment, as presumably I now have, yet it is very simple, in fact, only such as many other plants should have; but, unlike them, A. tetragona will take no alternative; it must have partial shade, sandy peat or leaf soil, and be planted in a moist or semi-bog situation. On the raised parts of rockwork it became burnt up; planted in loam, though light, it was dormant as a stone; in pots, it withered at the tips; but, with the above treatment, I have flowers and numerous branchlets. Many little schemes may be improvised for the accommodation of this and similar subjects. Something of the bog character would appear to be the difficulty here; a miniature one may be made in less than half an hour. Next the walk dig a hole 18in. all ways, fill in with sandy peat, make it firm; so form the surface of the walk that the water from it will eddy or turn in. In a week it will have settled; do not fill it up, but leave it dished and put in the plant. Gentians, pyrolas, СКАЧАТЬ
