Panax (Ginseng). Araliaceæ.
Cuttings of stems and roots. Stems of old plants may be cut into pieces an inch or two long and inserted in sand in heat. Or young plants can be obtained by cutting down the tops of strong plants and then separating the suckers which arise.
Pancratium and Hymenocallis. Amaryllideæ.
Seeds, sown in pans in heat, are sometimes employed. Commonly increased by offsets, which usually form freely.
Pandanus (Screw Pine). Pandaneæ.
Seeds and suckers, as in palms. Also by cuttings of the young growth in heat. The “seeds” are really fruits, and if in good condition several plants, one to ten, are obtainable from each; they should be separated when well furnished with roots.
Pansy. See [Viola].
Seeds—usually sown out-doors—and divisions. P. orientalis and allied species are easily propagated by root-cuttings in sandy soil under glass in autumn.
