Flowering period, June to September.
Achillea Filipendula
This grows 4ft. high, and the foliage, though fern-like, has an untidy appearance, from the irregular way in which it is disposed. It is herbaceous, and comes from the Caucasus. The flowers are somewhat singular, arranged in corymbs of a multiplex character; they are very large, often 5in. across. The smaller corymbs are arched or convex, causing the cluster or compound corymb to present an uneven surface; the small flowers are of rich old gold colour, and have the appearance of knotted gold cord; they are very rigid, almost hard. The leaves are linear, pinnate, lobed and serrated, hairy, rough, and numerously produced. From the untidy and tall habit of this subject, it should be planted in the background; its flowers, however, will claim a prominent position in a cut state; they are truly rich, the undulating corymbs have the appearance of embossed gold plate, and their antique colour and form are compared to gold braid by a lady who admires "old-fashioned" flowers. It will last for several weeks after being cut, and even out of water for many days. A few heads placed in an old vase, without any other flowers, are rich and characteristic, whilst on bronze figures and ewers in a dry state, and more especially on ebony or other black decorations, it may be placed with a more than floral effect. In short, rough as the plant is, it is worth growing for its quaint and rich flowers alone; it is seldom met with. Soil and propagation, the same as for A. Ægyptica.
Flowering period, June to September.
Achillea Millefolium
This is the well-known wild Yarrow; it is, however, the typical form of a fine variety, called A. m. roseum, having very bright rose-coloured flowers, which in all other respects resembles the wild form. Both as a border subject and for cutting purposes, I have found it useful; it flowers for several months, but the individual blooms fade in four or six days; these should be regularly removed. The freshly-opened corymbs are much admired. Soil and mode of propagation, the same as for previous kinds.
Flowering period, June to November.
Achillea Ptarmica
A very common British plant, or, I may say, weed, which can live in the most reeky towns, only mentioned here to introduce A. P. fl.-pl., which is one of the most useful of border flowers. I am bound to add, however, that only when in flower is it more presentable than the weedy and typical form; but the grand masses of pure white bachelors'-button-like flowers, which are produced for many weeks in succession, render this plant deserving of a place in every garden. It is a very old flower in English gardens. Some 250 years ago Parkinson referred to the double flowering kind, in his "Paradise of Pleasant Flowers," as a then common plant; and I may as well produce Gerarde's description of the typical form, which answers, in all respects, for the double one, with the exception of the flowers themselves: "The small Sneesewoort hath many rounde and brittle braunches, beset with long and narrowe leaues, hackt about the edges like a sawe; at the top of the stalkes do grow smal single flowers like the fielde Daisie. The roote is tender and full of strings, creeping farre abroade in the earth, and in short time occupieth very much grounde." The flowers of this plant are often, but wrongly, called "bachelors' buttons," which they much resemble.
For cutting purposes, this plant is one of the most useful; not only are the blooms a good white, but they have the quality of keeping clean, and are produced in greater numbers than ever I saw them on the single form. Those requiring large quantities of white flowers could not do better than give the plant a few square yards in some unfrequented part of the garden; any kind of soil will suit it, but if enriched the bloom will be all the better for it. The roots run freely just under the surface, so that a large stock may soon be had; yet, fine as are its flowers, hardy and spreading as the plant proves, it is but seldom met with. Even in small gardens this fine old flower should be allowed a little space. Transplant any time.
Flowering period, June to August.
Aconitum Autumnale
Fig. 2. Aconitum Autumnale.
(About one-tenth natural size.)
Hardy, perennial, and herbaceous. This is one of the finest subjects for autumn flowering. The whole plant, which stands nearly 3ft. high, is stately and distinct (Fig. 2); the leaves are dark green, large, deeply cut and veined, of good substance, and slightly drooping. The flowers are a fine blue (a colour somewhat scarce in our gardens at that season), irregularly arranged on very stout stems; in form they exactly resemble a monk's hood, and the manner in which they are held from the stems further accords with that likeness. These rich flowers are numerously produced; a three-year-old plant will have as many as six stout stems all well furnished, rendering the specimen very conspicuous.
This is one form of the Monk's-hood long grown in English gardens, and is called "old-fashioned." A. japonicum, according to some, is identical with it, but whether that is so or not, there is but a slight difference, and both, of course, are good.
I find it likes a rich deep soil. It is propagated by division of the roots after the tops have turned yellow in autumn or winter.
It flowers from August until cut down by frosts.
Allium Moly
A hardy bulbous perennial, of neat habit, with bright golden flowers, produced in large heads; they endure a long time and are very effective; it is by far the best yellow species. Where bold clumps of yellow are desirable, especially if somewhat in the background, there can be few subjects more suitable for the purpose than this plant; both leaves and flowers, however, have a disagreeable odour, if in the least bruised. It is a very old plant in English gardens, and is a native of the South of Europe. Its chief merits are fine colour, large head, neat habit, and easy culture. The flowers are 1in. across, borne in close heads, having stalks over an inch long springing from stout scapes; the six long oval petals are of a shining yellow colour; the seed organs also are all yellow and half the length of petals; the scape is about a foot high, naked, round, and very stout; the leaves are nearly as broad as tulip leaves, and otherwise much resemble them.
Flowering period, June to August.
Allium Neapolitanum
This has pure white flowers arranged in neat and effective umbels, and though not so useful in colour as the flowers of A. Moly, they are much superior to those of many of the genus.
Flowering period, June to August.
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
