WORTHY PLANTS FOR GREENHOUSE 131 Bougainvillea.—A beautiful climber. Will do well in greenhouse or conservatory, though usually grown in a stove. Propagated by cuttings in heat.

Good loam made open with sand or road grit and sweet with charcoal will suit most kinds. Camellias.—Generally grown on a wall or as tub plants, and need little attention beyond sponging.

Propagate by cuttings or division, and grow in cold house. Canna.—Besides being useful in beds, cannas make a
