It may be transplanted, any time from September to the end of January, into good light loam or leaf soil, 4in. or 6in. deep; if there should be a dry season during the period of growth, the plant should be well watered. To increase it, the tubers may be divided every third year, providing the growth has been of a vigorous tone. I may add, that, from its tall and not over-dense habit, there may with advantage, both to it and the plants used, be a carpet grown underneath—ivy, vincas, or sweet woodruff for some situations, and brighter subjects for more conspicuous parts of the garden, such as the finer kinds of mimulus, ourisia, alpine aster, and dwarf iris.
Flowering period, June and July.
Arum Crinitum
As may be seen by the illustration (Fig. 17), this is a most singular plant. It proves hardy in this climate if its position is selected; in other words, it is not hardy in all kinds of soils and situations, but if planted four or five inches deep, in sandy or half decayed vegetable mould, facing the south, there is little to fear either as regards hardiness or its thriving. I think, therefore, it may be called hardy. It is far more interesting than handsome, but there is at the present time an evident desire amongst amateurs to grow the various Arums, and more especially has this one been sought after; I have, therefore, introduced it amongst more beautiful flowers, and given an enlarged drawing of the entire plant, together with the spathe in its unopened state.
The plant is a native of Minorca, and was imported in 1777. In this climate it grows to the height of 18in., developing the flower with the foliage. It is produced on a stout scape nearly 1ft. high, of a pale green colour, marked with dark short lines and spotted with delicate pink dots. The folded spathe is of leather-like substance, rough, almost corky in texture; also variously marked and tinted. At the base there are a number of green lines arranged evenly and longitudinally on a nearly white ground. A little higher—the belly part—the lines are less frequent, irregular, and mixed with pink dots. Still higher, the ground colour becomes pale green, the lines dark green, and the pink spots are changed to clouded tints; the remainder of the folded spathe—to the tip—is a mixture of brown and green dots, the total length being fully 9in. When the spathe opens, it does so quickly, bending more than half its length outwards, the division looking upwards. To those who have not before seen the plant at this stage, it will prove an interesting surprise; the odour, however, is repulsive. The spathe at its widest part is 6in. broad, and tapers off to a blunt point. It is of a dark purple colour and covered with long bent dark hairs, whence the specific name. They are curiously disposed, and remind one of some hairy animal that has been lifted out of the water the wrong way as regards the direction of the hair. The spadix is comparatively small, black, and also covered with hairs. The flower should be closely watched if its peculiarities are to be fully noted, as it not only opens quickly but soon begins to wither. During the short period that the flower is open the lower part of the spathe or belly becomes filled with all kinds of flies, being held by the spear-like hairs.

The leaves have long stalks, marked and tinted in a similar manner to that of the scape. They are curiously formed and twisted, pedate or bird-foot shaped, the outer segments twice cut, lance-shaped, and turned inwards or over the main part of the leaf; the leaves are of a deep green colour, and of good substance; they seldom exceed four in number to each plant or tuber.
This curious species should, as above indicated, have a warm situation, where it will also be comparatively dry in winter. Its propagation may be effected by division of the roots of strong specimens.
Flowering period, June and July.
Asters
Hardy, perennial, and herbaceous. These are a numerous family, and many of them have an ungainly habit and insignificant flowers—in fact, are not worth growing, save as wild flowers in unfrequented places. I will mention a few of the finer sorts, which are mostly species: A. diversifolius, A. ericoides, A. grandiflorus, A. pendulus, and A. Dumosus, these are all good, both in habit and flowers; ericoides and pendulus make really handsome bushes, but the very beautiful A. amellus, and its more dwarf variety (A. Mdme. Soyance), have tempted me to write of these old-fashioned plants, which may be said to be wholly distinct, as their flowers are so very much brighter (dark purple, with a clear yellow centre), and the rays so much more evenly and compactly furnished. Their stems are 2ft. to 3ft. high, and flowered half their length with clusters of bloom about the size and form of full-grown field daisies. These wand-like spikes in a cut state are bright and appropriate decorations. In vases they are very effective, even when used alone. The flowers are very lasting, either cut or otherwise; the plants will bloom six or eight weeks.
These subjects will thrive in almost any kind of soil or position, opening their flowers during the dullest weather, and though they like sunshine, they will not wait for it. It is scarcely needful to further describe these well-known flowers, but, as well as the species, there are some bright and beautiful varieties which merit further notice. All the Starworts are easily increased by root division any time.
Flowering period, August to November.
Aster Alpinus
An exceedingly beautiful and very much admired alpine plant, which does not die down like most of the Starworts, but has woody stems; it is seldom seen more than a foot high, and its large bright purple flowers seem disproportionate. This is one of the plants which should have a place in every garden, and more especially in rock gardens. There cannot well be a more neat and telling subject; the form and size of its flowers are not often seen on such dwarf plants, and it also has the merit of being a "tidy" subject when not in bloom. The illustration (Fig. 18) will give a fair idea of its main features. Its purple flowers, which are fully 2in. across, have for many days an even and well-expanded ray, when the florets curl or reflex; the disk is large, and numerously set with lemon-yellow florets; the flowers are well lifted up on stout round stems, covered with short stiff hairs, and furnished with five or six small leaves; the main foliage is of compact growth, lance-shaped, entire, spathulate and covered with short hairs.

Considering that this plant has been in English gardens for 220 years, and that its merits must be seen by anyone at a glance, it is hard to say why it is not better known; even in choice and large collections it always proves attractive when in flower. The blooms in a cut state are very durable; they not only hold together, but also keep a good colour. Under cultivation it is in no way particular; it will endure anything but being deprived of light; from its dwarf, stout, and shrubby character, it would form a useful and a handsome edging to the larger walks; and by growing it so extensively an enviable supply of flowers for cutting would be at hand.
A stock of young plants may soon be got up by division of strong roots after the flowering season; such pieces as have roots may be planted at once in their permanent quarters; the rootless parts should be dibbled into light sandy loam and shaded with branches for a week or two.
Flowering period, June and July.
A. a. albus is a white-flowered variety, blooming about the same time. There does not appear to be that vigour about it which characterises the type; this, however, is not the only shortcoming; when compared with the rich purple flower,
