Lemon Verbena is among the most pleasant-smelling plants in the world. Rubbing or bruising or cooking with the foliage releases a clear, delicious lemon smell, very similar to that of lemon grass, and more lemony than most lemons. The flowers are tiny white things in loose, airy clusters at the ends of branches, definitely not a showy display. The leaves are 3 to 4 inches long and about ½ inch wide, medium green and glossy, and deciduous. They usually grow in whorls of three, but sometimes there are four leaves at a whorl or only two. With regular trimming, it can bush out quite nicely, and is a classic subject for topiary standards.
