Philodendron. Aroideæ.
Increased by seeds; and by dividing the stems, allowing two or three joints to each piece, inserting them in pots in a brisk heat.
Phlomis. Labiatæ.
All of the species may be increased by seeds; the herbaceous kinds by divisions, and the shrubby sorts also by cuttings.
Phlox. Polemoniaceæ.
The annuals are grown from seeds sown in the open. The perennials are grown from seeds, divisions, cuttings of stems and roots. Cuttings made during summer, and handled in a frame, do well. The roots are cut into short pieces, and are then handled in pans or flats under cover.
Phœnix, Elate (Date Palm). Palmæ.
Increased by imported seeds, sown in a sandy soil, in a mild hot-bed. Also by suckers. See also [Date].
