Hardy Perennials and Old Fashioned Flowers

Triteleia Uniflora

Sometimes called Milla Uniflora; One-flowered Triteleia, or Spring Star Flower; Nat. Ord. Liliaceæ

This is a favourite flower, and in some soils increases very fast; it is the commonest species of the very limited genus to which it belongs; was brought from South America only so recently as 1836, and it is already extensively grown in this country, and as a trade article is very cheap indeed, thanks to its intrinsic worth. Though small, its star-like form gives it a lively and effective appearance in the borders. It is much used by the Americans as a window and greenhouse plant, notwithstanding that it is a wild flower with them, and its pretty shape and lovely hues render it eligible for such uses, but on account of the esteem in which is held the odour of garlic, I should not like to recommend it for such close associations. The flower in shape is, as the generic name implies, like the Trillium, formed of three, or rather threes; the divisions are arranged in threes, or triangularly; the two triangles, being crossed, give the flower a geometrical and star-like effect. The flowers, which are 1in. to 2in. across, are borne on slender stems, 4in. to 6in. long. They are nearly white, but have various tints, bluish reflections, with a line of blue in each petal. The leaves resemble those of the snowdrop when overgrown and turning flabby, and have a somewhat untidy and sprawling habit; they are abundantly produced from the rather small cocoon-shaped bulbs. On the whole, the plant is very ornamental when in flower, and the bloom is produced more or less for many weeks; at any rate, it is an early flower, and if it cannot be used indoors it should be extensively planted amongst border subjects, than which there are few more hardy or reliable. Propagated by divisions of the crowded bulbs every other year, during late summer.

T. u. lilacina (the Lilac-coloured Star Flower) is a most handsome variety, having, as implied by the name, a richly coloured flower. I am indebted to a lady for roots and flowers recently sent me; so far as I know, it is not yet generally distributed. It is very distinct from the type in having smaller parts throughout, and a more highly coloured bloom, with the outer surface of the shining tube of a darker or brownish-green colour. I have seen a mauve coloured form, but this is much more pronounced and effective. The chief recommendation of this otherwise desirable flower, to my thinking, is its rich, new-mown hay scent; in this it differs much from the parent form.

Flowering period, March to May.

Tritoma Uvaria

Great Tritoma; Common Names, Flame-flower, Red-hot Poker; Nat. Ord. Liliaceæ-Hemero-callideæ

This is one of our finest late-flowering plants; it has, moreover, a tropical appearance, which renders it very attractive. It is fast becoming popular, though as yet it is not very often seen in private gardens; it comes from the Cape of Good Hope, its year of introduction being 1707. In this climate, when planted in well-exposed situations and in sandy loam, it proves hardy but herbaceous; if protected it is evergreen; and I ought to add that if it is planted in clay soil, or where the drainage is defective, it will be killed by a severe winter; but when such simple precautions as are here indicated will conduce to the salvation of a somewhat doubtful plant, it may be fairly termed hardy. According to my experience during severe winters, plants in wet stiff loam were all killed, but others of the same stock, in light sandy earth, did not suffer in the least. I have also made similar observations outside my own garden.

The stout scapes or stems sometimes reach a height of 4ft., and are topped with long or cocoon-shaped spikes of orange and red flowers; the flowers are tubular and small, closely arranged, and drooping; each will be about an inch long, and the spikes 6in. to 8in. long. The leaves are narrow, 2ft. to 3ft. long, keeled, channelled, and rough on the edges, of a dark green colour and prostrate habit. Either amongst trees or in more conspicuous positions this flower proves very effective, whilst in lines it is simply dazzling; when grown in quantity it may be cut for indoor decoration, than which few large flowers are more telling.

Cultural hints have already been given in speaking of its hardiness, but I may add that where the soil is naturally light and dry a liberal dressing of well-rotted manure may be dug in with great benefit to the flowers. It is readily propagated by division of the roots every third year; the young stock should be put in rows, the earth having been deeply stirred and well broken; this may be done in late autumn or spring—if the former, a top dressing of leaves will assist root action.

This bold and brilliant flower appears in September, and is produced in numbers more or less to the end of the year, provided the season does not set in very severe.

Tropæolum Tuberosum

Tuberous Tropæolum; Nat. Ord. Tropæolaceæ

All the species of this genus are highly decorative garden subjects, including the annual varieties, and otherwise they are interesting. They are known by various names, as Trophy-plant, Indian Cress, and Nasturtium, though the latter is only applicable strictly to plants of another order. The plant under notice is a climber, herbaceous and perennial, having tuberous roots, whence its specific name; they much resemble small potatoes, and are eaten in Peru, the native country of the plant. It has not long been grown in this country, the date of its introduction being 1836; it is not often seen, which may be in part owing to the fact of its being considered tender in this climate. But let me at once state that under favourable conditions, and such as may easily be afforded in any garden, it proves hardy. As a matter of fact, I wintered it in 1880-1, and also in 1881-2, which latter does not signify much, as it proved so mild; but it must be admitted that the first-mentioned winter would be a fair test season. The position was very dry, viz., on the top of a small bank of earth, against a south wall; the soil was sandy loam, and it was overgrown with ivy, the leaves of which would doubtless keep out many degrees of cold, as also would the dryness of the soil; another point in favour of my specimen proving hardy, would be the fact of its exposure to the sun, by which the tubers would be well and duly ripened. It is one of the handsomest trailers or climbers I know for the herbaceous garden; a free grower, very floriferous, bright, distinct, and having a charming habit. The illustration (Fig. 106) can give no idea of the fine colours of its flowers, or richly glaucous foliage. One specimen in my garden has been much admired, thanks to nothing but its own habit and form; under a west wall, sheltered from the strong winds, it grows near some Lilium auratum; after outgrowing the lengths of the stems, and having set off to advantage the lily bloom, it caught by its tendril-like shoots an apricot tree on the wall, and then reached the top, being furnished with bloom its whole length. The flowers are orange and scarlet, inclining to crimson; they are produced singly on long red stalks, which spring from the axils of the leaves; the orange petals are small and overlapping, being compactly enclosed in the scarlet calyx; the spur, which is also of the same colour, is thick and long, imparting a pear-like form to the whole flower, which, however, is not more than 1½in. long. The leaves are nearly round in outline, sub-peltate, five, but sometimes only three-lobed; lobes entire, sometimes notched, smooth and glaucous; the leaf-stalks are long and bent, and act as tendrils. The plant makes rapid growth, the stems going out in all directions, some trailing on the ground.

It is a good subject for the drier parts of rockwork, where a twiggy branch should be secured, which it will soon cover. It is also fine for lattice work, or it may be grown where it can appropriate the dried stems of lupine and larkspurs. For all such situations it is not only showy, but beautiful. The flowered sprays are effective in a cut state, especially by gaslight; they come in for drooping or twining purposes, and last a long time in water.

(One-fifth natural size.)

If grown as a tender plant its treatment is as simple as can be; the tubers may be planted in early spring in any desired situation, and when the frosts at the end of the season have cut down the foliage, the tubers may be taken up and stored in sand; but if it is intended to winter it out the situation should be chosen for its dryness, and the soil should be of a sandy nature, in which the tubers ought to be placed 5in. or 6in. deep. It is self-propagating, the tubers being numerously produced; and like "potato sets," the larger ones may be cut in pieces; if, however, numbers are not the object they are better left uncut. Caterpillars are fond of this plant; at the first sight of an eaten leaf, they should be looked for and destroyed.

It begins to flower in the latter part of summer, continuing until stopped by frosts.

Umbilicus Chrysanthus

Nat. Ord. Crassulaceæ

Fig. 107. Umbilicus Chrysanthus.

 

(One-half natural size.)

This is a very pretty and distinct subject, and never fails to flower very late in the year. It is a plant having the appearance of being tender, and is not often seen growing fully exposed in the garden; it is, however, perfectly hardy, enduring any amount of cold; it suffers more from wet. It is also evergreen. Its soft dull or greyish-green rosettes are in marked contrast with the rigid and shining sempervivums, in the company of which it is frequently placed. It is an alpine subject, and comes from the mountains of Asiatic Turkey, being also found more west. Not only is it interesting, but its pretty form and habit are qualities which render it very useful in a garden, more especially for dry parts, such as old walls and rockwork.

It grows 6in. high, the older rosettes elongate and form leafy flower stalks, which are topped by drooping panicles of flowers, somewhat bell shaped; each flower is ¾in. long, of a yellowish white colour; the petals are finely pointed, and well supported by a fleshy calyx; the bloom is slowly developed and very enduring, even when the worst weather prevails. The leaves are arranged in flat rosette form (the rosettes from 1in. to 2in. across), lower leaves spathulate, those near the centre more oval.

All are fleshy, covered with short hairs, and somewhat clammy to the touch. Its habit is neat, and it adorns such situations as otherwise suit it, viz., banks or risen beds, and such other positions as have already been named.

Its culture is easy, but it ought to have the compost it most enjoys—peat and grit—and it should be sheltered from the strong winds, otherwise its top-heavy flower stalks will be laid prostrate. When it once finds a happy home it increases fast; the thick stalks are procumbent and emit roots. These may either be left to form large specimens or be taken off during the growing season for stock. Excessive wet is its greatest enemy. For such subjects, the wire and glass shelters are not only a remedy, but very handy.

Flowering period, summer, until stopped by frosts.

Vaccinium Vitis-Idæa

Red Whortle-berry; sometimes called Cow-berry; Nat. Ord. Vaccinaceæ

Although a native evergreen, and in some parts occurring extensively, it proves to be both decorative and useful as a garden subject; as a neat evergreen it is worthy of a place, especially when it is not to be found near in a wild state. It is seldom seen without either its waxy and pink-tinted white flowers or its bright clusters of red berries, but in October it carries both, which, together with the fine condition of the foliage, renders the shrub most attractive. It grows 6in. to 9in. high under cultivation.

In form the flowers somewhat resemble the lily of the valley, but they are closely set in the stems and partly hidden, owing to the shortness and drooping character of the racemes; not only are the flowers pleasingly tinted, but they exhale a full and spicy odour; the buds, too, are tinted with a lively pink colour on their sunny sides. The berries are quickly developed, being nearly the size of the holly berry, but a more bright red. The leaves are stout, shining, and leathery, and ofttimes pleasingly bronzed. They are over ½in. long and egg-shaped, being bent backwards. The stems are furnished with short hairs, are much branched, and densely foliaged. This compact-growing shrub would make a capital edging, provided it was well grown in vegetable soil. It would go well with Erica carnea to form a double line, either to a shrubbery or permanent beds of dwarf flowering trees. Now that berries are so much used for wearing about the person and for indoor decoration, those of this shrub may become useful. A dishful of sprigs in October proves pleasant both to the sight and smell, the flowers and fruit being charmingly blended.

Fig. 108. Vaccinium Vitis-idæa.

(Natural size.)

V. v.-i. major is a variety which is simply larger in all its parts; it is, however, rather more bronzed in the foliage. I daresay by many it would be preferred to the typical form, both for its robust and decorative qualities. It is nearly twice the size of the type.

As may be inferred, both from the order to which this shrub belongs and the localities where it occurs in its wild state, a peaty or vegetable soil will be required. I find the species grow most freely in a mixture of leaf soil and sand, the position being moist but exposed. It does not object to a little shade, but then its useful berries are neither so numerously produced nor so well coloured.

It is easily propagated by division at almost any time.

Flowering period, May to October.

Veronica Gentianoides

Syn. V. Gentianifolia; Gentian-leaved Speedwell; Nat. Ord. Scrophulariaceæ

This is a distinct and pleasing species, viewed as a garden plant. It is very hardy, and one of the herbaceous kinds; it has been grown in English gardens nearly 150 years, and came originally from the Levant. It is pretty widely used, but it deserves a place in every garden; not only are its tall spikes of flowers effective during their season, but the foliage, compared with other Veronicas, is of a bright and plump character. The newly-formed tufts, which are somewhat rosette-shaped, have a fresh appearance throughout the winter, it being one of the few herbaceous subjects in which the signs of life are so visible in this climate.

The flowers are small-½in. in diameter—numerously produced on spikes 18in. high. They are blue, striped with light and dark shades; both calyx and corolla, as common to the genus, are four-parted, petals of uneven size. The flower spikes are finely developed, the flowers and buds occupying 12in. of their length, and tapering off to a point which bends gracefully. The buds are not less pretty than the flowers, resembling as they do turquoise in a deep setting of the calyx. The leaves are smooth, shining, and of much substance, 3in. to 6in. long, and 1in. to 2in. broad, lance-shaped, serrated, and sheathing. They are of a somewhat clustered arrangement close to the ground. Good pieces of this plant, 1ft. to 2ft. across, are very effective, and flower for a good while.

The rich and graceful spikes are of great value for vase decoration, one or two sufficing in connection with other suitable flowers.

There is a lovely variety of this species called V. g. variegata; in shape and habit it resembles the type though scarcely as vigorous, but not at all "miffy." The leaves are richly coloured pale green, white, and pink; and the flowers, as seldom occurs in variegated forms, are larger and more handsome than in the parent; in all respects, it is as useful, and, for forming an edging, perhaps more suitable than the common form.

Both kinds like a good fat loam and a moist situation; they may be grown either in borders or on rockwork, but specimens on the latter compare poorly with those grown otherwise; either they are too dry, or the soil gets washed from them, so that the new roots, which strike down from the surface-creeping stems, do not find the needful nourishment. Their increase is easily effected by division of the rooted stems any time after they have done flowering. If the season is droughty, they should be well watered.

Flowering period, May to July.

Veronica Pinguifolia

Fat-leaved Speedwell; Nat. Ord. Scrophulariaceæ

This is a rather uncommon species, being of the shrubby section, but unlike many of its relative kinds, it is perfectly hardy, also evergreen and very dwarf; a specimen three or four years old is but a diminutive bush, 18in. through and 8in. high. The habit is dense, the main or old branches are prostrate, the younger wood being erect and full of very short side shoots.

The flowers are produced on the new wood; the chubby flower-spikes issue from the axils of the leaves near the leading shoot; in some cases there are three, in others four, but more often two. Each flower spike has a short, stout, round stem, nearly an inch long, and the part furnished with buds is nearly as long again. At this stage (just before they begin to open) the buds are rice-shaped, snow white, waxy, and arranged cone form. They are, moreover, charmingly intersected with the pale green sepals in their undeveloped stage. The little bunches of buds are simply exquisite. The flowers are small, pure white, waxy, and twisted in the petals. The two filaments are longer than the petals, having rather large anthers, which are bright purple. This pleasing feature, together with the young shoots in the midst of the blossoms, which have small stout glaucous leaves tipped with yellow—nearly golden—give the clusters a bouquet-like appearance. The leaves are small—little more than half an inch long—and ovate, slightly cupped, stem-clasping, and opposite. They are a pale glaucous hue, and closely grown on the stems; they greatly add to the rich effect of the flowers.

This shrub is a most fitting subject for rockwork, and it would also make an edging of rare beauty, which, if well grown, no one could but admire. It seems to enjoy loam and leaf soil in a moist but sunny situation. It may be propagated by cuttings, taken with a part of the previous year's wood.

Flowering period, May to July.

Veronica Prostrata

Prostrate Speedwell; Nat. Ord. Scrophulariaceæ

This is sometimes confounded with V. repens, I presume from the slight distinction in the specific names, but so different are the two species that no one who has seen them can possibly take one for the other. V. repens is herb-like; it creeps and roots, and has nearly white flowers in April; but V. prostrata is a deciduous trailer, and the more common and best form has fine gentian-blue flowers; it is a capital rock plant, being most effective when hanging over the face of large stones. The flowers are small, and produced in rather long sprays, which are numerous, so that little else than flowers can be seen for two or three weeks.

It will grow and flower freely in any soil, but the aspect should be sunny; it is easily increased by division or rootlets. I may add that the very long stems of this prostrate plant (when in bloom) are well adapted for indoor decoration. Where pendent, deep blue flowers are needed, there are very few good blues so suitable.

Flowering period, May to July.

Vesicaria Græca

Nat. Ord. Cruciferæ

This beautiful, diminutive, hardy evergreen shrub comes to us from Switzerland, being an alpine species (see Fig. 109).

Fig. 109. Vesicaria Græca.

(One-third natural size; 1, full size.)

When in flower it does not exceed the height of 6in. or 8in., at which time it is very showy, covered, as it is, with flowers of the brightest golden yellow, surpassing the golden alyssum, which in some respects it resembles, being half woody, possessing greyish leaves, and dense heads of flowers, which, however, are arranged in small corymbs, and being also much larger. The leaves of the flower stalks resemble lavender leaves in general appearance; those of the unproductive stems are larger, and arranged sparingly in rigid rosette form, such unproductive stems being few.

The neat and erect habit of the plant renders it most suitable for rockwork or edgings, and otherwise, from its long continued flowering, which will exceed a month in moderate weather, it is one of the most useful spring flowers; whilst, for cutting purposes, it cannot but rank with the more choice, as, combined with extra brightness of colour, it exhales a rich hawthorn perfume. To all who have a garden, big or little, I would say, grow this sweet little shrub. It has never failed to do well with me in any situation that was fully exposed; it flowers freely in a light dry bed, but on rockwork it is most at home. The quickest way to prepare plants of flowering strength is to divide strong pieces; but this interferes with the larger specimens, which are by far the best forms in which to grow and retain it. Another mode is to cut off all the flowers nearly down to the old wood; side shoots will thus be induced to grow earlier than otherwise, so that in late summer they may be taken off as slips, and there will still be plenty of time to strike them like wallflower slips, and get plenty of roots to them before the cold weather sets in. The plant also produces seed freely in its inflated pods, which affords another, but more tedious, way of increasing it.

Flowering period, April to June.
