Piper

Pepper. Twenty-seven species. Stove evergreen shrubs. Cuttings and suckers; loam and peat. On the culture of the Black Pepper, (P. nigrum,) Dr. Lindley observes, that "it grows luxuriantly in many stoves, but is shy in ripening its fruit. This is probably owing to the uniform moisture which is kept in these places. It should be planted in a large tub or box well drained, all the strong flower-bearing shoots should be supported with strong stakes, and the small useless ones cut away. When not growing much, keep it rather dry, and give it a slight check, and be careful not to give it too much water after flowering. Bottom heat, particularly when growing, is indispensable." - Gard. Chron.
