Aralia (Meaning unknown ORD Araliaceoe)
(meaning unknown). ORD. Araliaceoe. This widely-grown genus includes stove, greenhouse, and hardy, herbaceous and shrubby plants. Flowers inconspicuous, umbellate, the umbels usually disposed in panicles; petals five, inserted on the margin of the disk; stamens five. Leaves usually compound. These plants are of moderately free growth, and the majority are easy to manage. Those requiring indoor treatment thrive well under the ordinary routine of management. One most important requirement, however, is that they must be kept well supplied with water at the roots. The finer, or stove varieties, should be potted in a mixture of sandy loam and peat, with the addition of a little fibrous leaf soil, and sufficient sand to keep the whole porous. The stronger growing kinds thrive in a richer compost. Propagation by cuttings of the roots is a common and very successful method. To obtain the roots, one of the strongest plants should be turned out of the pot, and the roots should be cleared of soil by shaking or washing it out; the requisite number of pieces should then be selected. As each piece is removed, it should have the end nearest the stem cut horizontally, to distinguish it from the other or furthermost end. In planting cuttings of the roots, it is best to place the end nearest the stem uppermost. The pieces may be left about 2in. long, and should be inserted in pots, well drained, and filled with sandy soil, leaving the tops of the cuttings about level with the surface of the soil. A square of glass must be placed over the top of each pot, plunging them in moderate bottom heat. The stems of the plants from which the roots have been taken may be cut into pieces 1in. or 1 1/2in. long, leaving an eye or bud near the top; a slice of half the shoot may be taken off opposite the bud. When prepared, these pieces should be pressed into pots of sand or sandy soil, and plunged into bottom heat. The stems may be cut down without disturbing the roots; in that case, if the pots are plunged in bottom heat, and kept moderately supplied with water, they will probably throw up several suckers or shoots from the roots. These, if taken off with a portion of root to each, and placed in small sized pots, will, with a little care, soon make useful plants. All the hardy species and most of the greenhouse ones are propagated readily by cuttings or pieces of roots. Some of the stove species, however, are very difficult to increase, except by grafting. Among these are A. leptophylla, A. Veitchii, &c. These should be worked on stocks of A. Guilfoylei or A. reticulata, the latter being the better of the two. Cuttings of either of these strike readily, and stocks fit for grafting are easily procured. In sheltered and warm positions, the greenhouse species are admirably suited for subtropical gardening, either planted singly or in groups.
