Boronias.

Greenhouse evergreen shrubs. A single plant of B. Megastigma is sufficient to perfume a good-sized house. B. Drummondi, Elatior, Heterophylla, and Serrulata are all good plants. The pots should be filled with sandy peat and be well drained. They are propagated by cuttings taken at a joint and placed under glass. May is their flowering month. Height, 2 ft.
