Part 18
_Amaryllis._ This is a genus of splendid flowering bulbs containing about eighty species, and one hundred and forty varieties. They are natives of South America, but more than one half of them are hybrids grown from seed by cultivators. They are generally kept in the Hot-house, but in our climate will do perfectly well in the Green-house; and we have no doubt that in a few years many of them will be so acclimated, as to keep as garden bulbs, planting about the end of April, and lifting them in October. As the beauty of these plants is in the flowers, it will be proper to give a small description of a few of them. _A. striatifòlia_, has a stripe of pure white in the centre of each leaf, the flowers are purple and white, an esteemed species. _A. Johnsòni_, the flowers are a deep scarlet, with a white streak in the centre of each petal, four bloom on a stem of about two feet, each flower about six inches diameter; a bulb well established has two stems. _A. regìna_, Mexican Lily, has large scarlet pendant flowers, tube of the flower fringed-like, with three or four on the stem. _A. vittàta_ is an admired species with scarlet flowers, striped with a greenish white. There are two or three varieties of it; corolla campanulate, three or four on the stem, about five inches diameter; petals a little undulate. _A. fùlgida_, flower scarlet, large tube striped, petals acute, two flowers on the stem. _A. áulica_ is one of the most magnificent, has four flowers about seven inches diameter, erect on a stem about two and a half feet high; six petals, strongly united to the capsule, bottom of the petals green, connected with spots of dark crimson, which spread into fine transparent red, covered with rich tints, nerves very perceptible, anthers bold. It is called crowned _Amaryllis_. _A. psittácina_, Parrot Amaryllis, is scarlet striped with green, two flowers on the stem, each about five inches diameter. There are several varieties of it; the best that we have seen are _cowbèrgia_ and _pulverulènta_. A bulb known in our collections as _A. purpùrea_ is _Ballóta purpùrea_, has beautiful erect scarlet flowers, three or four on the stem, each about five inches in diameter. There are three varieties of it, differing only in habit. _A. longifòlia_ is now _Crìnum capénse_, and is perfectly hardy; flowers pink, inclining to white, in large umbels, leaves long, glaucous, and is a desirable garden bulb.
There are many other superb Amaryllis, especially the hybrid sorts; from _Johnsòni_ there are above twenty cultivated varieties; from _formòsa_ above twelve; and from _Griffìni_ about ten, all of them esteemed. Where they have been kept in the earth in which they were grown last year, the ball ought at this repotting to be reduced; when the bulbs are done flowering, they ought to have little water, so that they may be perfectly ripened, which will cause them to produce their flowers more freely.
_Araucària._ This noble genus contains four species, which are without exception the handsomest plants we are acquainted with, for the beauty of their foliage, and symmetry of their growth, that belong to the Green-house. _A. excélsa_, Norfolk Island Pine, has leaves closely imbricated as if with a coat of mail, and are imperishable. _A. imbricàta_, Chile Pine, is one of the grandest of trees, and is the hardiest of the genus; the leaves are also closely imbricated. The other two species are rarely seen even in European collections. The foliage of either of the species will adhere to the wood many years after the plant is dead. They are all highly valued, the pots must be well drained; for if the plants get much water while dormant, the foliage becomes yellow, and never attains its beautiful green colour again; otherwise they are easily grown.
_Chamærops._ There are about seven species of these palms: four of them belong to this department, and are the finest of those that will keep in the Green-house. They all have large palmated fronds, and require large pots or tubs to make them grow freely, and are tenacious of life if kept from frost.
_Gardènia._ This is an esteemed genus of plants, especially for the double flowering varieties, which are highly odoriferous, and have an evergreen shining foliage. _G. flòrida flòre-plèno_, Cape Jasmine, is a plant universally known in our collections, and trees of it are frequently seen above seven feet high and five feet in diameter, blooming from June to October. _G. rádicans_, dwarf Cape Jasmine, _G. longifòlia_, and _G. latifòlia_, are also in several collections, but not so generally known; the flowers are double, and all equally fragrant. We are inclined to think they are only varieties of _G. flòrida_. Any of the above will keep in the coldest part of the Green-house, and even under the stage is a good situation for them, where the house is otherwise crowded during winter. They must be sparingly watered from November to March. Much water while they are dormant, gives the foliage a sickly tinge, a state in which they are too frequently seen. _G. Rothmànnia_ and _G. Thunbérgia_ are fine plants, but flower sparingly; the flowers of the former are spotted, and are most fragrant during night.
_Mesembryànthemum._ A very extensive genus, containing upwards of four hundred and fifty species, and varieties, with few exceptions natives of the Cape of Good Hope. They are all singular, many of them beautiful, and some splendid; yet they have never been popular plants in our collections. The leaves are almost of every shape and form; their habits vary in appearance. Some of them are straggling, others insignificant, and a few grotesque. When they are well grown, they flower in great profusion; the colours are brilliant, and through the genus are found of every shade; yellow and white are most prevalent. Each species continues a considerable time in flower. The flowers are either solitary, axillary, extra axillary, but most frequently terminale; leaves mostly opposite, thick, or succulent, and of various forms. They are sometimes kept in the Hot-house, but undoubtedly the Green-house is the best situation for them. They must not get water above once a month during winter, but while they are in flower and through the summer, they require a more liberal supply, and they seldom need to be repotted; once in two years is sufficient.
_Strelítzia_, a most superb genus of evergreen perennial plants. They are greatly esteemed and highly valued in our collections. The finest flowering species are _S. regìnæ_ and _S. ováta_; the former is the strongest of the two, but in respect to the beauty of their flowers there is no difference. The scape arises about three feet, headed with a sheath which lies horizontal before the flowers burst forth. The sheath contains three, four, or five flowers, according to the strength of the plants. These arise erect, and pass in a few days to the bottom of the sheath, the one before the other. _S. hùmilis_ is another fine species, but the most rare are _S. agústa_, which has a leaf nearly like the plantain; _S. jùncea_, _S. parvifòlia_, and _S. farinòso_. The flowers of all these are yellow and blue, except those of _S. agústa_, which are white, and it flowers sparingly. A few species of these plants ought to be in every Green-house: they are vulgarly called Queen plant. While in flower they should be liberally supplied with water, but while dormant very sparingly. They will suffer sooner from the effects of too much, than too little water. The roots are strong tubers, and require plenty of pot room, and will thrive exceedingly where they can be planted in the soil.
CAMELLIAS.
These plants, when they are brought from the Green-house, ought to be set in a situation by themselves, that they may be the more strictly attended to in watering and syringing. An airy situation where the sun has no effect upon them is the best. They should be syringed every evening when there has been no rain through the day. After heavy rains examine the pots, and where water is found, turn the plant on its side for a few hours to let the water pass off, and then examine the draining in the bottom of the pots, which must be defective.
CAPE BULBS.
As soon as these are done flowering, and the foliage begins to decay, cease watering, and turn the pots on their sides, until the soil is perfectly dry; then take out the bulbs and preserve them dry until the time of planting, which will be about the end of August or first of September.
=Flower Garden.=
_MAY._
It is highly desirable to have all the scientific operations as much advanced in the beginning of this month as is practicable, that at all times immediate attention may be given to the destroying of weeds wherever they appear.
ANNUALS, HARDY AND TENDER.
By the first of the month finish sowing all hardy Annuals and Biennials; and about the middle of the month all those that are tropical. The weather being now warm, they will vegetate in a few days or weeks. Attend to thinning of those that are too thick, giving gentle waterings to such as are weak in dry weather. Those that have been protected in frames should be fully exposed therein night and day; take the first opportunity of damp cloudy days to have them transplanted into the borders or beds, after the 10th, lifting them out of the frame with as much earth as will adhere to their roots.
CARE OF HYACINTHS, TULIPS, &c.
For the treatment of these while in bloom, see last month. The best time to take them out of the ground is about five weeks after they are done flowering, or when the stem appears, what may be termed half decayed. The best method to dry them is to place the roots in rows, with bulb to bulb, the stems laying north and south, or east or west. Give the bulbs a very thin covering of earth, merely to exclude the sun, so that they may not dry too rapidly, being thereby liable to become soft. When they have thoroughly dried in this situation, which will be in eight or ten days in dry weather, (and if it rains cover them with boards,) take them to an airy dry loft or shade, clearing off the fibres or stems, and in a few weeks put them in close drawers, or cover them with sand perfectly dry, until the time of planting, for which see October.
It is not advisable to allow any of the bulbs of either Hyacinths or Tulips to seed, as it retards their ripening, and weakens the root, except where there are a few desired for new varieties. The small offsets must be carefully kept in dry sand, or immediately planted.
ANEMONES AND RANUNCULUS.
These while in bloom should be carefully shaded from the sun by hoops and thin canvass, or an erect temporary awning; and as soon as they are done flowering, they must be fully exposed, and the waterings given up.
DAHLIAS, TUBEROSES, AND AMARYLLIS,
That are not planted, should now be done. For full directions see last month. In many seasons, any time before the twelfth is quite soon enough; but nothing ought to be delayed when the season will permit it to be done. It is necessary to have them properly labeled.
AURICULAS, POLYANTHUS, AND PRIMROSES.
They will now be done flowering, but still must be carefully kept in a cool, shady situation, and all decayed leaves cut off as soon as they appear. Examine them carefully and frequently, in case slugs of any description be preying upon them. A dusting of hot lime will kill them, or they may be otherwise destroyed. Some have recommended to repot and slip those plants when done flowering, "or they will contract a destructive disease;" which disease is a loss of verdure, and is induced by too much heat and drought, and a few other causes from inattention; but if attended to as above until September, when they should be fresh potted, they will have time to be sufficiently established before winter, which is the most judicious time to take off slips, for two reasons, viz.--they do not need so much nursing through the most precarious season of the year (summer) for these plants, and they begin to grow, and will root afresh sooner.
DOUBLE WALL-FLOWERS.
As these are very seldom grown from seed, and are semi-biennials, art has to be used to preserve or renew them. About the end of this month take shoots of this year about three inches long, cutting them carefully off, and smoothing the cut end with a sharp knife; from this cut the lower leaves off about one inch and a half, and then put it in the ground; choose a very shady spot, mixing the soil with a little sand and earth of decayed leaves. Sprinkle them three times a day until they have taken root, which will be in a few weeks. Keep the cuttings about four inches apart.
GENERAL OBSERVATIONS.
We do not consider that it is essential every month to repeat the necessity of tying up plants, saving seeds when ripe, cutting down weeds, raking, &c. with many other similar observations. We have already been full on these subjects, and expect these to be remembered through the season. Particular care, however, is required to _carnations_, _pinks_, or any plants that have heavy heads and slender stems. If carnations are desired to flower strongly, cut off all the buds except three, leaving the uppermost and any other two of the largest. All climbing plants should have timely support, and tied securely every week while they are growing.
=Rooms.=
_MAY._
All the plants will be able to withstand exposure, in the general state of the seasons, about the 10th of the month. Begin about the first to take out the hardiest, such as _Laurestínus_, _Hydrángeas_, _Roses_, _Primroses_, _Polyanthus_, &c. and thus allow the others to stand more free, and become hardened to exposure. The reason that plants are so often seen brown, stunted, and almost half dead, is from the exposed situation they are placed in, with the direct sun upon them, and too frequently from being so sparingly watered. There are no shrubby plants cultivated in pots that are benefited by the hot sun from this period to October. A north aspect is the best for every plant, except _Càctus_, _Aloe_, _Mesembryànthemum_, and such as go under the name of succulents. Where there are only a few, they should be conveniently placed, to allow water from a pot with a rose mouth to be poured frequently over them, which is the best substitute for the syringe. _Dáphne_, _Coronílla_, _Fúchsia_, _Caméllia_, _Primrose_, and _Polyánthus_, do not agree with a single ray of the sun, through the summer. There has been a general question what is the cause of the death of so many of the _Dáphne odòra_. It may be observed, that the first place that shows symptoms of decay, is at the surface of the soil, and this takes place a few weeks before there are evident effects of it. The cause is from the effect of heat or sun and water acting on the stem at least. If the soil is drawn in the form of a cone round the stem, to throw off the water to the edges of the pot, that the stem may be dry above the roots, mortification does not take place, neither do they die prematurely, when thus treated. For further remarks, see Green-house, this month.
CAPE BULBS.
Any of these that are done flowering, such as _Ixia_, _Oxalis_, _Lachenàlia_, &c. as soon as the foliage begins to decay, turn the pots on their sides, which will ripen the roots, and when perfectly dry, clear them off the soil, wrap them up in paper, with their names attached, and put them carefully aside until the time of planting.
REPOTTING.
Where it is required, repot _Cáctus_, _Aloe_, _Mesembryánthemums_, and all other succulents, with any of the _Amaryllis_ that are required to be kept in pots, also Cape Jasmines. For description of the above, see Hot-house and Green-house of this month, under the same head.
=Hot-House.=
_JUNE AND JULY._
As the plants of the Hot-house are all exposed to the open air, the directions will include both months. If the repotting is over, as recommended last month, all the attention they will require until the end of August, is the administering of water at the roots, and by the syringe over head. It will be impossible to say how great are their wants, that depending entirely upon the nature of the plant, the situation, and the season; but never neglect to look over them every evening, and after very dry nights they will need a fresh supply in the morning, observing to give to none except they are becoming a little dry. Make weekly examinations for insects of any description, and when they appear, have them instantly destroyed.
Always after heavy rains look over the pots, in case water should be standing in them, which would injure the roots. Where any is found, turn the pot on its side, and in a few hours examine the draining which is defective; small pots in continued rains should be turned likewise.
Tie up all plants and shoots to prevent them from being destroyed by the wind, and be attentive to pick all weeds from the pots. Turn round all the plants occasionally, to prevent them from being drawn to one side by the sun or light.
=Green-House.=
_JUNE AND JULY._
The plants being out of the house, there need be little added under this head. Their treatment is in the general, and the required attention is in giving water according to their different constitutions and habits. Where there are not rain or river water, it should stand at least one day in butts or cisterns, to take the chilly air from it, and become softened by the surrounding atmosphere. This is more essential to the health of the plants than is generally supposed. The small plants in dry weather will need water evening and morning. Continue regular syringings as directed last month. There are frequently rains continuing for several days, which will materially injure many plants, if they are not turned on their sides until the rain is over, especially small plants. The syringings should never be done till after the waterings at the roots, and they should never be seldomer than every alternate evening. Turn all the plants frequently to prevent them from being drawn to one side by the sun or light. Carefully look over them at these turnings, to detect any insects. And observe that the tuberose rooted geraniums, such as _Ardéns_, _Bicòlor_, _Trístum_, &c. are not getting too much water, they being now dormant.
=Flower Garden.=
_JUNE AND JULY._
HOLLAND BULBS.
The lifting of these will be general in June. For directions see _May_. It is not advisable to take up _Jonquils_, _Fritillària_, _Crocus_, and _Iris_, oftener than every alternate year; _Jonquils_ may stand three years. _Anemones_ and _Ranunculus_ should be carefully lifted after their leaves begin to fade. Do not expose them to the sun, but cover slightly with earth or sand until they are perfectly dry, when they may be sifted out of the earth, and put into drawers carefully labeled. Some recommend to soak these roots in soap-suds, to destroy a worm that they are frequently attacked with. We know not how far this may be carried, nor the good or bad effects, never having practised it.
AUTUMN FLOWERING BULBS.
These are _Amaryllis lùtea_, now called _Sternbérgia lùtea_; _A. Belladónna_, now _Belladónna purpuráscens_; and _Nerìne sarniénsis_. This is a beautiful flowering bulb, and requires the protection of a frame during winter. The old bulb seldom flowers oftener than two succeeding years, and then decays, but the off-sets will flower the second year; therefore when the old bulbs are lifted, they ought to be immediately planted, and receive every encouragement to strengthen them for flowering. _Crôcus satìvus_, _C Pallàsii_, _C. serotìnus_, and _C. nudiflòrus_, and all the species of _Cólchicum_, with species of several other genera not introduced into the country. They should all be lifted as soon as the foliage is decayed, and kept only a few weeks out of the ground, and then again replanted in fresh soil. The economy of the genus _Cólchicum_ in regard to its bulbs, flowers, and seeds, is altogether singular, and may be termed an anomaly of nature. In producing the new bulbs or off-sets in a very curious manner, the old one perishes. The flowers which arise with long slender tubes from the root die off in October, without leaving any external appearance of seeds. These lie buried all the winter within the bulb, in spring they grow upon a fruit stalk, and are ripe about the first of June. How beautiful and admirable is this provision! The plant blooming so late in the year, would not have time to mature its seeds before winter; and is, therefore, so contrived that it may be performed out of the reach of the usual effects of frost, and they are brought above the surface when perfected, and at a proper season for sowing.
CARNATIONS AND PINKS.
In order to make the former flower well, if the weather is dry, give them frequent waterings at the root, and tie them up neatly to their rods. The criterion of a fine carnation is--the stem strong and straight, from thirty to forty inches high, the corolla three inches diameter, consisting of large round well formed petals, but not so many as to crowd it, nor so few as to make it appear thin or empty; the outside petals should rise above the calyx about half an inch, and then turn off in a horizontal direction, to support the interior petals, they forming nearly a hemispherical corolla. The interior petals should decrease in size toward the centre, all regularly disposed on every side; they should have a small degree of concavity at the lamina or broad end, the edges perfectly entire. The calyx above one inch in length, with strong broad points in a close and circular body. The colours must be perfectly distinct, disposed in regular long stripes, broadest at the edge of the lamina, and gradually becoming narrower as they approach the unguis or base of the petal, there terminating in a fine point. Those that contain two colours upon a white ground are esteemed the finest.
Of a double pink--the stem about twelve inches, the calyx smaller but similar to a carnation; the flowers two inches and a half in diameter; petals rose edges; colour white, and pure purple, or rich crimson; the nearer it approaches to black it is the more esteemed; proportions equal as in carnation. Those that are very tasteful with these flowers are attentive to the manner of their opening. Where the calyx is deficient in regular expansion to display the petals; that is, where there is a tendency to burst open on one side more than on the other, the opposite side in two or three different indentions should be slit a little at several times with the point of a small sharp knife, taking care not to cut the petals, and about the centre of the calyx tie a thread three or four times round to prevent any farther irregularity. Some florists and connoisseurs place cards on them. This is done when the calyx is small. Take a piece of thin pasteboard, about the size of a dollar; cut a small aperture in its centre to admit the bud to pass through. When on tie it tight to the rod, to prevent the wind from blowing it about; and when the flower is expanded, draw up the card to about the middle of the calyx, and spread the petals one over the other regularly upon it. When these plants are in flower, their beauty may be prolonged by giving them a little shade from the mid-day sun by an awning of any simple description. Where they are in pots, they can be removed to a cool shady situation, (but not directly under trees.)
