Polianthes (Tuberose). Amaryllideæ.
Increased by bulbels. Remove these from the parent bulb in the fall, and keep in a warm, dry place until the following spring. The soil should be light, rich and moist throughout the summer. Before frost comes in the fall, take the bulbs up, and when dry, cut off the leaves. The bulbs should be kept as during the preceding winter, and the culture during the following year is the same as during the first. The bulbs usually flower the second or third summer.
Polyanthus. See [Primula].
Polycarpæa. Caryophylleæ.
The annuals are increased by seeds; perennials by cuttings.
