This universally liked plant is commercially known the world over as lemon verbena. It is classed as a deciduous shrub and is the sole representative of the genus. Where hardy I doubt whether it is quite deciduous. It makes a fine plant when planted against the wall or pillar in the greenhouse, but it is as a sweet scented plant for our gardens that we most prize it, and every mixed border, and every garden, large or small, has one or more. The florist finds this a most useful plant for cutting in the summer time, for what can be more welcome in a bunch of flowers than a few sprays of the sweet lemon verbena?
Don't sell out clean in the spring. Save a dozen plants and shift them on, plunging them outside in pots in summer. At the approach of frost bring them in and stand them under your lightest and coolest bench and give them only water enough to keep the wood from shrivelling. In early February we shake them out. shorten back the unripened and weak wood and start them going again in fresh soil and pots, with us a 4-inch. Placed in a temperature of 55 degrees, in a few weeks they are covered with young growths which are just the thing for cuttings. They root easily but not nearly so surely as many of the soft-wooded plants. I prefer the sand to be a little warmer than the house. Keep the sand well soaked, twice a day is not too often, and never let the cuttings wilt from the sun or dryness.
In April we shift them from a 2-inch to a 3-inch pot and plunge in a mild hotbed, where by the middle of May, with one pinching, they will have made fine, bushy plants. They want lots of syringing to prevent red spider, and if the proper fumigation is regularly given they will not be troubled with fly. A florist should always be supplied with them, for they are usually difficult to procure when wanted.
