MUCH has been written on this subject in Europe, and many plants tried for the purpose, with more or less success, which in a great measure depends on the season, which is proverbially uncertain, especially in England; but enough success has attended the trial of many fine foliaged plants previously generally grown in hothouses all the year, to vary the uniformity and monotony of large masses of flowering plants.

In this country, many hothouse plants are far more satisfactory in the open ground than under glass during the hot summer months, and grow with a vigor and rapidity unknown in the cold, dull climate of England. But here comparatively little advantage has been taken of those advantages; and the effort has been used in trying to have such plants as variegated geraniums make an equal display to those seen in English gardens. This I consider a mistake, the climate being so very different; that a real satisfactory flower-bed to last in full beauty for, say, three months would be seldom seen. With few exceptions, the extent of subtropical gardening here has been a few large masses of Coleus Versohaffeltii,. the poorest varieties of Cannas and Caladium Esculentum; these are very well as a beginning, but variety is charming, and having such a large variety to choose from, we should make use of many others, which might be planted in large quantities in the splendid publio parks without destroying the natural scenery, but rather adding the luxurious growth of the tropics to the tropical climate.

Some of your readers may make an objeotion to the expense of this style of gardening; but, after the first outlay, it is in reality less than keeping up a supply of flowering plants; and where large quantities are required to be stored, the space required in comparison to the size of plants is small, and many species can be stored better in a dry cellar just free from frost than in a greenhouse.

I will mention a few of the most showy and easily grown plants, such as may be termed everybody's plants.

First, I must place Cannas, of which we have now varieties with very handsome foliage and also large and very showy flowers. Some of the varieties, as Heliconi-folk and Auguste Ferrier, will grow eight or more feet high, with large musci-like foliage, while Adele Levalloie will display its dazzling crimson flowers when but two feet high, while Tricolor gives us beautiful variegated foliage. These plants will grow in any rich soil in full sun or shade, but much better in former, and can be Stored like potatoes in the winter.

Another fine plant is the Aralia Papyrifera. Its large palmata leaves are very striking. This grows as free as the Canna in rich soil, and may be laid by the roots in soil in the cellar, and planted out again in May.

The Phormium Tenax, or New Zealand Flax, is another very useful plant; also the beautiful, variegated variety of the above; but this is rather scarce and high-priced. These are best planted in a moist place, or supplied with abundance of water; and to be kept in a moderate light place in winter. A little frost will not hurt these.

The Acorae Japonicae Variegatae is a very beautiful plant for edging beds or borders of other foliage plants, or for planting clumps or margins of ponds and lakes. It is most satisfactory in moist ground. This can remain in ground during winter; it is perfectly hardy.

Arundo Donax Versicolor is a magnificent plant for a large patch near water, the center of large beds, or the back of a border. It will grow ten feet high, and has a very light and graceful look, when its beautiful, variegated leaves are waved by the wind. This is said to be hardy; but I prefer taking it up and preserving it from hard frost. The tall stems can be cut down; it will push others from the bottom.

Many of the Solanums may be raised from seed and are ornamental; some for foliage, and others, as Ciliata, for the fruit.

The finest varieties of Caladiums are also very desirable for the above purpose. I planted out over twenty sorts, and most of them made large and beautiful colored leaves, many of them superior in color to the same kinds inside. Keep this, in winter, with Tuberose roots.

The Alternantheras are indispensable for hedgings, and the color of grandifolia and amabilis tricolor is very striking; but they require keeping during winter in a warm greenhouse.

Coleus are so well known that I need not say much in praise of them, and we have so many sorts, it is difficult to select, but as many of the rich colors indoors are not at all the same planted out, I will mention Verschaffeltii as best dark, and Princess Royal as best golden.

In a future article I will mention a few of the more rare ornamental plants which are very desirable for this purpose. In this I have confined myself to a few easily managed by any novice.

Subtropical Gardening #1

Very fine examples of this style were seen this fall, by the members of the American Pomological Society, who visited, by invitation, the residences and grounds of \Vm. Gray, Jr., and H. H. Hunnewell.

In front of the greenhouse, at Mr. Gray's, were quite a large number of beds along the paths, planted with rare and novel varieties of geraniums, cannas and ornamental grasses.

One bed, circular, consisted of a brilliant, beautiful flowering geranium - the Pink May Queen. Another was planted with the Chrystal Palace Gem, with scarlet blossoms and white variegated foliage. Quite a curiosity in gardening was it to see many of the beds edged with a strip of ivy, about a foot wide, growing low over the soil.

One bed, perhaps the most brilliant of all, consisted of the Gen. Grant Geranium, edged all around with the Golden Pyrethrum as a border.

In another bed, perfectly circular, and ten feet in diameter, were cannas of various sorts, with the Achy ran thus Verschaffeltii as border.

Another bed, ten feet wide by twenty long, was made up of solid mass of Achy-ranthus, then a border of striped grass, while in the center rose one single stem of tall and graceful grass, the variegated Pampas Grass.

Still another bed, circular, and about ten feet in diameter, had its soil carpeted with the variegated Abutilon (vexillaria variegata), out of which rises, in the center, cannas and caladiums.

In the triangle, near the greenhouses, were fifteen beds of different sizes, beds a perfect mass of Mountain of Snow Geraniums.

One bed consisted of Gen. Grant Geranium with the pyrethrum as border.

Another bed has for its border the coleus, and variegated geraniums in the center.

In the little greenhouse were noticed many pots of ferns, one of which we think is a new and rare species of the "Adiantum."

A pretty feature there attracted our notice, which we have never seen elsewhere. The sides of the walls of the house were lined with moss, kept moderately moist, and supported by wire rods, crossing frequently like diamonds before it. In this space of enclosed moss was planted and growing Sellaginella or Ferns, one of the prettiest of which is the Silver Fern.

The idea is a most unique one, and very feasible, as well as successful.
