Part 30 (1/2)
The PITCAIRNIA is a very handsome species, having long narrow leaves, with, spined edges and throwing up blossoms in upright spines.
The _Long Stamened Pitcairnia_, P. staminea, is a splendid scarlet flower, lasting long in blossom, which, appears in July or August, and continues till December.
The _Scarlet Pitcairnia_, P. bromeliaefolia, is also a fine rich scarlet flower, but blossoming somewhat sooner, and may be made to continue about a month later.
_Propagation_--is by dividing the roots, or by suckers, which is best performed at the close of the rains.
_Soil, &c._ A sandy peat is the favorite soil of this plant, which should be kept very moist.
The DAHLIA, Dahlia; a few years since an attempt was made to rename this beautiful and extensive family and to call it Georgina, but it failed, and it is still better known throughout the world by its old name than the new. It was long supposed that the Dahlia was only found indigenous in Mexico, but Captain Kirke some few years back brought to the notice of the Horticultural Society, that it was to be met with in great abundance in Dheyra Dhoon, producing many varieties both single and double; and he has from time to time sent down quant.i.ties of seed, which have greatly a.s.sisted its increase in all parts of India. It has also been found in Nagpore.
A good Dahlia is judged of by its form, size, and color. In respect to the first of these its _form_ should be perfectly round, without any inequalities of projecting points of the petals, or being notched, or irregular. These should also be so far revolute that the side view should exhibit a perfect semicircle in its outline, and the eye or prolific disc, in the centre should be entirely concealed. There has been recently introduced into this country a new variety, all the petals of which are quilled, which has a very handsome appearance.
In _size_ although of small estimation if the other qualities are defective, it is yet of some consideration, but the larger flowers are apt to be wanting in that perfect hemispherical form that is so much admired.
The _color_ is of great importance to the perfection of the flower; of those that are of one color this should be clear, unbroken, and distinct; but when mixed hues are sought, each color should be clearly and distinctly defined without any mingling of shades, or running into each other. Further, the flowers ought to be erect so as to exhibit the blossom in the fullest manner to the view. The most usual colors of the imported double Dahlias, met with in India, are crimson, scarlet, orange, purple, and white. Amongst those raised from seed from. Dheyra Dhoon[137] of the double kind, there are of single colors, crimson, deep crimson approaching to maroon, deep lilac, pale lilac, violet, pink, light purple, canary color, yellow, red, and white; and of mixed colors, white and pink, red and yellow, and orange and white: the single ones of good star shaped flowers and even petals being of crimson, puce, lilac, pale lilac, white, and orange. Those from Nagpore seed have yielded, double flowers of deep crimson, lilac, and pale purple, amongst single colors; lilac and blue, and red and yellow of mixed shades; and single flowered, crimson, and orange, with mixed colors of lilac and yellow, and lilac and white.
_Propagation_--is by dividing the roots, by cuttings, by suckers, or by seed; the latter is generally resorted to, where new varieties are desired. Mr. George A. Lake, in an article on this subject (_Gardeners'
Magazine_, 1833) says: ”I speak advisedly, and from, experience, when I a.s.sert that plants raised from cuttings do not produce equally perfect flowers, in regard to size, form, and fulness, with those produced by plants grown from division of tubers;” and he more fully shews in another part of the same paper, that this appears altogether conformable to reason, as the cutting must necessarily for a long period want that store of starch, which is heaped up in the full grown tuber for the nutriment of the plant. This objection however might be met by not allowing the cuttings to flower in the season when they are struck.
To those who are curious in the cultivation of this handsome species, it may be well to know how to secure varieties, especially of mixed colors; for this purpose it is necessary to cover the blossoms intended for fecundation with fine gauze tied firmly to the foot stalk, and when it expands take the pollen from the male flowers with a camel's hair pencil, and touch with it each floret of the intended bearing flower, tying the gauze again over it, and keeping it on until the petals are withered. The operation requires to be performed two or three successive days, as the florets do not expand together.
_Soil &c._ They thrive best in a rich loam, mixed with sand; but should not be repeated too often on the same spot, as they exhaust the soil considerably.
_Culture_. The Dahlia requires an open, airy position unsheltered by trees or walls, the plants should be put out where they are to blossom, immediately on the cessation of the rains, at a distance of three feet apart, either in rows or in clumps, as they make a handsome show in a ma.s.s; and as they grow should be trimmed from the lower shoots, to about a foot in height, and either tied carefully to a stake, or, what is better, surrounded by a square or circular trellis, about five feet in height. As the buds form they should be trimmed off, so as to leave but one on each stalk, this being the only method by which full, large, and perfectly shaped blossoms are obtained. Some people take up the tubers every year in February or March, but this is unnecessary. The plants blossom in November and December in the greatest perfection, but may with attention be continued from the beginning of October to the end of February.
Those plants which are left in the ground during the whole year should have their roots opened immediately on the close of the rains, the superabundant or decayed tubers, and all suckers being removed, and fresh earth filled in. The earth should always be heaped up high around the stems, and it is a good plan to surround each plant with a small trench to be filled daily with water so as to keep the stem and leaves dry.
The PINK, Dianthus, _Kurunful_, is a well known species of great variety, and acknowledged beauty.
The _Carnation_, D. caryophyilus, _Gul kurunful_, is by this time naturalized in India, adding both beauty and fragrance to the parterre; the only variety however that has yet appeared in the country is the clove, or deep crimson colored: but the success attending the culture of this beautiful flower is surely an encouragement to the introduction of other sorts, there being above four hundred kinds, especially as they may be obtained from seed or pipings sent packed in moss, which will remain in good condition for two or three months, provided no moisture beyond what is natural to the moss, have access to them.
The distinguis.h.i.+ng marks of a good carnation may be thus described: the stem should be tall and straight, strong, elastic, and having rather short foot stalks, the flower should be fully three inches in diameter with large well formed petals, round and uncut, long and broad, so as to stand out well, rising about half an inch above the calyx, and then the outer ones turned off in a horizontal direction, supporting those of the centre, decreasing gradually in size, the whole forming a near approach to a hemisphere. It flowers in April and May.
_Propagation_--is performed either by seed, by layers, or by pipings; the best time for making the two latter is when the plant is in full blossom, as they then root more strongly. In this operation the lower leaves should be trimmed off, and an incision made with a sharp knife, by entering the knife about a quarter of an inch below the joint, pa.s.sing it through its centre; it must then be pegged down with a hooked peg, and covered with about a quarter of an inch of light rich mould; if kept regularly moist, the layers will root in about a month's time: they may then be taken off and planted out into pots in a sheltered situation, neither exposed to excessive rain, nor sun, until they shoot out freely.
Pipings (or cuttings as they are called in other plants) must be taken off from a healthy, free growing plant, and should have two complete joints, being cut off horizontally close under the second one; the extremities of the leaves must also be shortened, leaving the whole length of each piping two inches; they should be thrown into a basin of soft water for a few minutes to plump them, and then planted out in moist rich mould, not more than an inch being inserted therein, and slightly watered to settle the earth close around them; after this the soil should be kept moderately moist, and never exposed to the sun. Seed is seldom resorted to except to introduce new varieties.
_Soil, &c._--A mixture of old well rotted stable manure, with one-third the quant.i.ty of good fine loamy earth, and a small portion of sand, is the best soil for carnations.
_Culture_.--The plants should be sheltered from too heavy a fall of rain, although they require to be kept moderately moist, and desire an airy situation. When the flower stalks are about six or eight inches in height, they must be supported by sticks, and, if large full blossoms be sought for, all the buds, except the leading one, must be removed with a pair of scissors; the calyx must also be frequently examined, as it is apt to burst, and if any disposition to this should appear, it will be well to a.s.sist the uniform expansion by cutting the angles with a sharp penknife. If, despite all precautions the calyx burst and let out the petals, it should be carefully tied with thread, or a circular piece of card having a hole in the centre should be drawn over the bud so as to hold the petals together, and display them to advantage by the contrast of the white color.
_Insects, &c._--The most destructive are the red, and the large black ant, which attack, and frequently entirely destroy the roots before you can be aware of its approach; powdered turmeric should therefore be constantly kept strewed around this flower.
The _Common Pink_, Dianthus Chinensis, _Kurunful_, and the _Sweet William_, D: barbatus, are pretty, ornamental plants, and may be propagated and cultivated in the same way as the carnation, save that they do not require so much care, or so good a soil, any garden mould sufficing; they are also more easily produced from seed.
The VIOLET, Viola, _Puroos_, is a cla.s.s containing many beautiful flowers, some highly ornamental and others odoriferous.
The _Sweet Violet_, V. odorata, _Bunufsh'eh_, truly the poet's flower.
It is a deserved favorite for its delightful fragrance as well as its delicate and retiring purple flowers; there is also a white variety, but it is rare in this country, as is also the double kind. This blossoms in the latter part of the cold weather.
