A correspondent says that the Messrs. Henderson, near London, grow extensively the following plants, in hanging baskets: "Hanging baskets were first introduced here, I believe, and now they find it a regular branch of business. All the AEchynanths they grow that way now; also Thyrsacanthus radians, Hoya bella, Cactus, or Epiphyllum truncatum Russellianum, and the crosses from them; Russellia junoea, which blooms in these baskets or basket-like pans, with holes in the sides and bottom, better than in pots. Campanula garganioa, they force in the stove, in these baskets, where it rambles like a climber; and when it comes into bloom, it is removed to a cool house, where you would hardly know it; and so with numerous kinds down to Aaron's Beard, the Saxifraga sarmentosa.

"The best six stove plants for hanging baskets (their own selection), are AEsehynanthus splendens, Hoya bella, Impatiens repens, Isolepis gracilis (also in the greenhouse, and out of doors in summer), Margravia dubia (with uncommonly fine foliage), and Torenia.Asiatica.

"The best twelve stove climbers: Allamanda Aubletil (yellow):Clerodendrum splendens and speciosissimum (two or three kinds of splendens are not worm growing); Combretum purpureum; Dipladenia acuminata, crassinoda, and splendens; Hexacentris Mysorensis, Hoya imperialis, Ipomaea Horsfalliae, Passiflora princeps, or raoemosa, P. Decaisnea, and Stephanotis floribunda.'1

The writer continues: "The newest thing in this nursery is from an original idea - a rare thing in gardening - a thirty-paned propagating house, forty feet by thirty-five feet, which trill be in three divisions, the tanks for bottom heat being the novelty. They are to be eighteen inches deep, with two flow and one return-pipe in each, and will be heated with Thomson's new retort boiler. The new idea for bottom heat is an improvement on all other modes of hot-water bottom heating. It is this: After the three pipes are proved in each bank, that tank is to be filled on the principle of the filter, first with big stones in the bottom, Mr say as large as ducks' eggs, then another layer of stones not so big; after that, a layer of very rough gravel, and another layer of gravel not so rough, and so on till the top is of the finest sand; then a foot of water is let in, and the pipes will heat the mass to 80º, more or less; and, when once that heat is got, a few hours' firing, daily, will keep it up, and a constant moist bottom heat is as certain as from a dung bed.

Three inches of clean sand sill keep down the vapor, and be the best way of bottom heating and plunging, and, in the autumn, the water will be withdrawn by turning a ceck; and then a dry bottom heat is secured for the winter, the mass of stones and gravel retaining the heat for days and days it little cost. This is a vast improvement on the old way of throwing in steam among stones for bottom or for more permanent heat, as was practised just at the time when the hot-water system was introduced".

Of new plants found at Henderson's, he says: " Jasminum dianthifolium, with a slender habit and sweet, starry, white flowers, was quite new to me as a store plant, which everybody buys for its manageable size and most deliciously sweet blossoms. Dipladenia uro-phylla and Allamanda Aubletii are spoken of as very superior; Ardisia hymenandra and AEschynanthus splendens, the same; Izora floribunda, a close grower, with rosy flowers, ditto; Rogeria thyrsi flora, much after Ixora, the same; Tecoma spectabilis, Meyenia erecta, and the magnific Medinilla, with Maranta Warscewiczii, the Hexacentris, Gesnera Doncklarii, Dipladenia acuminata, Nepenthes phyllamphora, the two Sonerila margaritacea, and Impatiens Jerdoniae, are all of the first water".

Another authority has the following interesting list: -

"Plants for rockwork, all with variegated leaves: Ajuga reptans, Aira caerulea (Molinia carulea), Carex, Dactylis glomerata, Festuca glauoa, Galeobdolon luteum, Glechoma hederacea, Linaria Cymbalaria, Saxifraga umbrosa, Tussilago Farfara, Vinca major elegantisaima, V. major reticulata, Y. minor aurea, Y. minor argentea.

Plants for pot culture: iEgopodium Podagraria, with variegated leaves, free growing, and handsome; variegated Ageratum coelestinum, Arabis lucida, with very fine bright golden variegation; Arundo Donax versicolor, one of the very best variegated plants; Artemisia vulgaris, handsome in a pot; Arum maculatum, with veined leaves; Aspidistra lurida variegata, generally shown as a stove plant, but quite hardy and very fine for specimen plants; Centaurea candidissima, with ornamental silvery leaves, makes a first-rate specimen plant; Cineraria maritima: this, like the preceding, is covered with down, which looks like frosted silver, an elegant plant for rooms at night; Convallaria majalis: this is even finer as a pot plant than in the border; Dactylis glomerata fol. var., a handsome Grass;

Festuca glauca, tinged with bine; Funkia albo-marginata, has a narrow white edge; F. ovata, bordered with white; F. nndulata, with a broad white belt in the middle - all three make handsome pot plants: Melissa secunda, has leaves mottled with white, dwarf habit, and a profusion of pretty rosy flowers; Mentha rotundifolia, with white border; M. sylvestris, pretty, frequently three colored; Polemonium caeruleum, a beautiful plant for pot culture; Pulmonaria sibirica, with very distinctly spotted leaves; Spiraea Ulmaria variegata, Tussilago Farfara, very beautiful as a specimen plant.

Fig. 2. Hanging Vase.

Plants for baskets or hanging vases: Glechoma hederacea, exceedingly pretty for this purpose; Linaria Cymbalaria, a diminutive plant, but remarkably pretty; Vinca major eleganti8sima, one of the finest variegated plants in cultivation; V. major reticulata, exceedingly elegant, the leaves looking like network; Y. minor aurea and Y. minor argentea.

Of many of these plants pretty specimens were shown by Mr. Salter at Regent's Park, where they were much admired. We may add that the beautiful Chinese Farfugium grande when it shall have become more common will doubtless be a great favorite both for pot culture and for rockwork".

The subject has taken strong hold of our American spirit of adorning home, and we are glad to lend our aid to so good a cause.
