VERBENA . The genus Verbena (vervain) in See also:

botany gives its name to the natural See also:order (Verbenaceae) of which it is a member. The See also:species are herbaceous or somewhat shrubby, erect or procumbent, with opposite or whorled leaves, generally deeply cut. The sessile See also:flowers are aggregated into See also:close spikes. Each See also:flower has a tubular, ribbed calyx, a more or less irregular tubular two-lipped corolla, with four (didynamous) stamens springing from the interior of the corolla-See also:tube. The anthers are two-celled, with or without a gland-like appendage at the See also:apex. The ovary is entire or four-lobed, and always four-celled, with a single ovule in each See also:cell; the See also:style is unequally two-lobed at the apex. The See also:fruit consists of four hard nutlets within the persistent calyx. There are about eighty species known, mostly natives of. tropical and subtropical See also:America, a very few species occur-See also:ring also in the Old See also:World. The vervein, or vervain, V. officinalis, native of central and See also:north See also:Asia, See also:Europe and North See also:Africa, and See also:common on dry See also:waste ground in the See also:south of See also:England (rarer in the north), was the See also:object of much superstitious veneration on the See also:part of our See also:pagan ancestors, who attributed marvellous properties to it, provided it were gathered in a particular manner and with much complex ceremonial. The plant is now but lightly esteemed, and its medicinal virtues are wholly discredited. The See also:garden verbenas are derivatives from various South See also:American species, such as V. teucrioides, a native of See also:southern See also:Brazil, and V. chamaedrifolia from See also:Argentina and southern Brazil.

The range of See also:

colours extends from pure See also:white to See also:rose-coloured, See also:carmine, See also:violet and See also:purple. Striped forms also are cultivated. The See also:lemon-scented verbena of gardens, so much valued for the fragrance of its leaves, was once referred to this genus under the name V. triphylla, subsequently called Aloysia, but is now referred to the genus See also:Lip pia as L. citriodora; it differs from Verbena in having two, not four, nutlets in the fruit. The garden verbenas, although somewhat misprized for some years, have once more become popular as bedding See also:plants, and also for pot culture. They are easily raised from seeds sown in See also:heat in See also:February or See also:March, but choice varieties, like See also:Miss Willmott and others, can only be kept true when raised from cuttings. These are best secured from old plants cut down in the autumn and started into growth in See also:gentle heat and moisture the following See also:spring. They See also:root readily in a compost of sandy See also:loam and See also:leaf See also:soil. Besides the garden varieties, V. See also:venosa, a Brazilian species with bluish-violet flowers, is a popular plant for massing in beds during the summer months.
