This is the well-known lemon-scented Verbena, a native of Chili. It is a shrubby plant with pale-green lance-shaped leaves remarkable for their deliciously fragrant scent. It was at one time grown in hundreds of thousands from cuttings of the young shoots in the same way as Fuchsias, but dropped down considerably of late years. There is, however, a revival in its trade, and nice bushy plants in 3}-in. and 5-in. pots find a ready sale. Older plants grown as bushes or standards are also in request. Growers should encourage florists to use shoots with cut flowers, but the plants must be grown hard for this purpose, otherwise the shoots are apt to wither too soon.
