Plate XLIX | Malphigia crassifolia | Thick-leaved Malpighia | Class X. Order III | Decandria trigynia. […] Our species makes a very handsome hothouse plant, growing to the height of five, or six feet, before it flowers. It is a native of Jamaica, and most of the adjacent islands, and was introduced by Messrs. Lee and Kennedy about the year 1792. From the extreme tenderness of the young leaves, and shoots, it must be kept in a strong growing pine heat during the winter months; otherwise, they are subject to damp off. It is raised by cuttings, and seems to delight in a rich soil. The figure was made from a specimen communicated by the Right Hon. Lord Viscount Courtenay, in whose most superb collection at Powderham Castle, near Exeter, it flowered, for the first time in England, in the month of September 1798.

[in the grounds of Powderham-castle] Under a hanging wood composed of an intermixture of firs and forest trees, hewn from the living rock, and separated from the Park by a high pale, is here to be seen a Grotto; not one of those damp subterranes, from whose dropping roof the pendulous Stalactites hangs, and over whose fretted floor the chrystalline rill gurgles: but a dry, cool Excavation, forming a delicious retreat from the Summer Sun. The shelly decorations intermingled with spar and moss, owe their arrangement to the taste of the fair Sisters of Lord Courtenay, by whose hands also have the Roses been planted, and the Woodbines trained which o’er canopy the entrance of the grot, and fill it with perfume. […] on a glade, in part open to the Sun are the pleasure gardens, formed within the last ten years by the direction of Lord Courtenay; These are much visited; and consisting of Pastures of the most beautiful flowers, interchanged by close shaven lawns, shrubberies, and a Summer building forming at once an elegant room and a conservatory for curious plants certainly deserve the attention of every Visitor of Powderham.

I went a few years since to view the castle […] There were some fine old lemon-trees, in full bearing, that grew in the natural ground at the end of a terrace, which were remarkable for being the first planted in the open ground in England. They were covered with glass frames only in the severity of winter; for the climate there, though rather less healthy than the opposite shore, is indisputably the Montpelier of England. There were also at that time at large in the park a nice breed of pyed pea-fowls

There are two great American aloes [Agave americana] in the orangerie of the Right Hon. Lord Borringdon, at Saltram, near Plymouth, one of them showing evident marks that it would blossom soon in full bloom, was removed for security, and to promote its blossoming in safety, by direction of Mr. Smith, principal gardener, and by order of the Right Hon. Lord Boringdon, from the orangerie into Saltram gardens, for the inspection of the curious in botany. There have been two of these grand plants that have blossomed in the last century, in the county of Devon; one about twenty-five years since at Powderham-castle, the seat of the Right Hon. Lord Courtenay; and a second about thirty years since blossomed in a gentleman’s garden at Salcombe, in the South-Hams, which at that time produced great profit to the respective gardeners, who exhibited it to the curious.

The Norfolk Island Hibiscus is a tender greenhouse plant; was introduced to Britain, in the year 1792, having been raised from seeds communicated by Col. Paterson, then stationed on that Island. It attains the height of 12 feet, or more, becoming a small tree; may be increased readily from cuttings, and should be planted in a mixture of loam and sandy peat. Our figure is from a specimen received from the Right Hon. Lord Viscount Courtenay, in whose collection at Powderham, near Exeter, it flowered for the first time in the year 1800; and where also the seeds ripened.

The grounds of Powderham are extensive, finely planted with deciduous and exotic trees, and diversified with some bold swells. […] The park and plantations belonging to this domain, extend through a circumference of nearly ten miles; and the pleasure gardens behind the house are replete with a vast number and variety of flowers and botanical rarities.

A conservatory to be executed for lord viscount Courtenay, at Powderham castle, Devon. | One fire, and a single flue goes round this house; the front part above the floor, the other under the pathway. A narrow border is formed along the back wall, which gives growth to plants trained upon a treillage fixed against the wall for that purpose. The front and end sashes are made to draw down from the top, for the purpose of admitting air. The top lights on the roof are made to slide, and to be taken entirely off in the summer. Plants, &c. are plunged or planted in the pit, which is level with the walk, and is bounded by a stone border, on which are formed small Gothic arches, with wire work. A small arch is formed with treillage under each rafter, at the angle it makes with the back wall.

Powderham Castle, the magnificent seat of Lord Courtenay, is surrounded with fine plantations. The pleasure-grounds are extensive, and laid out with considerable taste. The gardens contain a noble collection of exotics; many of the plants had attained an extraordinary size and luxuriance, occasioned most probably by the mildness of the air.

[We already have some double dahlias here of a suberb lilac colour, but the lord who lives in the château at Draveil has them in all colours with heads as big as peonies. He paid 25 guineas for each tuber, and the rough/rude beast would rather burn them than give any to his neighbours.]

Passing from the castle to the garden I enter into another person’s jurisdiction, and that person I know is no favorite of your Lordship’s. If I may be permitted however to express an opinion, as to the mode in which he discharges his duty from the observations I could make, I should say that there cannot be much, if any ground for complaint at present. I am a great admirer of plants but do not profess to be any judge as to their merits or particular claims for admiration. I can only say that Hall has an amazing large collection and according to my notions a most beautiful one. I certainly never saw any to equal them. […] With the management of the gardens and the arrangement made with Hall two years ago as to them and the preservation of the shrubberies and walks around the castle I have not interfered with. As respects the preservation and appearance of all these things I am convinced any alteration would be no improvement. As to the terms on which Hall holds the gardens I can scarcely venture to express an opinion about them. The rent he pays is certainly a mere nominal one, but the expense of keeping up the different hothouses etc. etc. must be very great, and if it be true as Mr. Pidsley informs me it is, that almost all the surrounding gentry in the neighbourhood of Exeter sell plants and the surplus produce of their gardens, the prices must naturally be so diminished as most materially to affect any profits Hall may make.

The gardens attached to the castle are extensive, and have been kept in the finest order: its flower-gardens likewise have been celebrated for their arrangement and choice collection of costly plants. The grounds are beautifully laid out, and so blend with the flower–garden, as to form a lovely whole. Here is still to be seen the rare exotic growing in all its native luxuriance, combined with the temple, the orchestra, and banqueting-room, that once gave life and soul to the scene.

You are a wicked woman for not being in raptures with Powderham. Who told you to expect carnations or anemonies or common annuals? In former days when the family were in its glory, tho to be sure their whole souls seemed wrapped up in their garden, they used to go when breakfast was over in open carriages & stay all day, dining there, a band of music under the trees, dancing on the grass, acting plays.

Au Directeur de l’Institut horticole. | Monsieur, j’ai l’honneur de vous rendre compte que les greffes herbacées que vous m’aviez prescrit de faire ont été effectuées, sous mes yeux, du 11 mai au 6 juin, sans autre interruption que les dimanches, par deux de nos bons jardiniers, Josselin et Hatesse, et deux candidats d’horticulture, Blanchard et Levacher […] Ces quatre hommes ont été occupés à l’opération pendant l’espace de vingt-cinq jours. Dans cet intervalle, il a été opéré deux mille deux cent soixante-trois sujets d’Azalées en pots (Azalea pontica) […] Environ cent cinquante espèces ou variétés et hybrides d’Azalées ont été multipliées ainsi. On y remarque une vingtaine de sujets de l’Azalea sinensis lutea, nouvelle espèce d’orangerie encore rare, végétant parfaitement bien […] Il a été vendu un de ces sujets de l’Azalea sinensis lutea, au bout de quarante-trois jours de greffe, à M. John Ballander, jardinier de lord Courtenay, propriétaire du château de Draveil.

[The horticultural institute in Fromont lay south of Paris and only a few kilometres from Draveil. In 1829 a small team of gardeners and students there had been attempting to graft more unusual varieties of azalea on to stocks of Azalea pontica. They were particularly successful with grafts from Azalea sinensis lutea, ‘a new and still rare type of hothouse plant’. There were some twenty healthy plants and one of these, forty-three days after grafting, was sold to ‘Mr John Ballander, gardener to Lord Courtenay who owns the château de Draveil.’]
