dug and well manured the flowers are vastly improved. Propagated by seed or division of the stout tap roots.
Flowering period, August to September.
Clethra Alnifolia
A hardy deciduous shrub, and mentioned in connection with herbaceous perennials because of its rich flowers and dwarf habit. It is a native of North America, having been grown in this country for 150 years; it is not so often met with as it ought to be, though much esteemed. It becomes very productive of flowers when only 2ft. high, but grows somewhat taller when well established; it is more valuable than common from its floriferousness, during late summer to the end of the season.
Let me at once state that its winning point is the delicious scent of its pure white flowers; it is very powerful, and like that of the lilac and alder combined; the racemes are 2in. or 3in. long, and compactly formed of short-stalked flowers less than ½in. across; they are of good substance, and in form resemble the lilac flower minus the tube; the flower stems are somewhat woody, and foliaged to the base of the spike or raceme. The leaves are of varying sizes, oval, lance-shaped, and short-stalked, distinctly veined and slightly wrinkled, sharp but finely toothed, of a dark shining green colour on the upper and a greyish-green on the under side. The whole shrub is somewhat rough to the touch; the habit is bushy and branching, increasing in size from suckers; the numerous twiggy side shoots of the previous year's growth produce the flowers.
It enjoys a light soil and sunny situation, and it may be planted anywhere in the shrubbery or borders as a first-class flowering subject. Its scent loads the air for some distance around, and pleasantly reminds one of spring flowers. Such sweet-smelling flowers are not too plentiful in September, and I know not a better one than this amongst hardy flowers for the late season. Its odour is fine and full; a single sprig now by me proves almost too much for the confinement of a room. This quality is invaluable in small flowers that can be freely cut, which, moreover, as in this case, are otherwise suitable for bouquet work. Propagated by cuttings and division of the suckers, taken when growth has ceased; if put in sandy loam and a warm situation, they will become rooted during the following spring.
Flowering period, August and September.
Colchicum Autumnale
A native bulbous perennial (see Fig. 25). The Colchicums are often confounded with the autumn-flowering species of croci, which they much resemble when in bloom; the similarity is the more marked by the absence, from both, of their leaves in that season, otherwise the leaves would prove to be the clearest mark of difference. Botanically they are far removed from each other, being of different orders, but there is no need to go into such distinctions, not, at any rate, in this case.
Fig. 25. Colchicum Autumnale
(about one-sixth natural size.)
The flowers are well known and they need not be described further than by saying they are in form crocus-like, but much longer in the tubes and of a bright mauve-purple colour. The bulbs have no resemblance to the crocus whatever, being often four times the size of the crocus corms. Moreover, they are pear-shaped and covered with flaky wrappers of a chestnut brown colour; if examined, these coverings will be found, near the neck of the bulb, to be very numerous and slack fitting, extending above the ground, where they have the form of decayed or blackened foliage; a singular fact in connection with the roots is, they are not emitted from the base of the bulb, but from the side of the thickened or ovate part, and are short and tufty. In early spring the leaves, which are somewhat like the daffodil, but much broader and sheathed, are quickly grown; at the same time the fruit appears. In summer the foliage suddenly turns brown, and in the autumn nothing is seen but blackened foliage, which is very persistent, and which, a little later, acts as sheaths for the long-tubed flowers. Unless the weather be very unfavourable, these flowers last a long time—fully two weeks. The double variety, which is somewhat scarce, is even more lasting, and I may add, it is a form and colour so softly and richly shaded that it is nothing short of exquisite; but the single variety, now more especially under notice, is also capable of agreeably surprising its friends when used in certain ways, for instance, as follows: A tray of the bright green and nearly transparent selaginella, so common in all greenhouses, should form the ground for twos or threes of these simple but elegant Saffron flowers; no other should be placed near—their simplicity forms their charm. It will be seen that the robust but soft-coloured flower of the meadows harmonises finely with the more delicately grown moss. In other ways this fine autumnal flower may be used with pleasing effect in a cut state, and it blends well with the more choice exotics. This is more than can be said of many hardy flowers, and it is fortunate that during dull weather, when we are driven from our gardens, there are still some flowers which may be hastily gathered and so arranged indoors as to give us all the pleasure which only such flowers can yield at such a season.
I find this subject to do well in any situation, but I think the blooms are a richer colour if grown under partial shade. The bulbs should not be disturbed if abundance of flowers are wanted; but if it is found desirable to propagate them, the bulbs may be lifted every two or three years, when the tops have withered, and when there will probably be found a goodly crop of young tubers.
Flowering period, September and October.
Colchicum Variegatum
This comes from Greece, nevertheless it is perfectly hardy; it is not only peculiarly pretty when closely examined, but a truly handsome flower, either as cut bloom or seen in groups in a growing state. Compared with C. autumnale, it is shorter in the tube, or more dwarf; still, it is a larger flower, and its rosy purple petals, or divisions of the corolla, are more spear-shaped, and each from 2in. to 3in. long; they have a stout and almost white mid-rib, the other parts of the segments being distinctly and beautifully chequered with white and rosy purple; the tube is stout, and of transparent whiteness; the foliage less than that of the British species, and more wavy. The habit of the flowers is erect, and during sunshine they become flatly expanded, when they will be 4in. to 5in. across, being 3in. to 4in. high. It is a very durable flower, lasting at least a fortnight, and many are produced from one bulb, appearing in succession, so that the blooming period is well extended; it braves the worst weather with little or no damage. Unlike the longer-tubed varieties, it is never seen in a broken state, and it is this which mainly renders it superior. Either as a cut flower, or a decorative subject for the borders or rockwork, it is a first-rate plant, being neat and showy.
It enjoys a sandy loam in a moist but warm situation; at the base of a small rockwork having a southern aspect it flourishes to perfection; it can hardly be planted wrongly provided there is no stagnant moisture. Propagated like C. autumnale, than which it is of slower increase.
Flowering period, September and October.
Coreopsis Auriculata
Fig. 26. Coreopsis Auriculata.
(one-fourth natural size.)
The oldest species of the genus grown in English gardens; its flowers are yellow, but dotted at the base of the ray florets. The leaves, as implied by the name, are dissimilar to other species, being lobed and having ear-like appendages; but this feature is far from constant, and otherwise the leaves differ, being sub-sessile and oval-lance-shaped (see Fig. 26). It came from North America as long ago as 1699. Slugs are very fond of these plants, and in winter more especially, when the dormant eyes are not only in a green, but exposed state; they should be watched after,
