The ripe seeds are lilac-purple, variegated with black, or deep purplish-brown,—the edge, or border, little, if any, marked; hilum long and white; form broad-kidney-shaped; size large,—if well grown, measuring seven-eighths of an inch long, six-tenths of an inch broad, and three-eighths of an inch thick. About five hundred and fifty are contained in a quart, and will plant eighty hills.
In this country, it is usually cultivated as an ornamental, climbing annual; the spikes of rich, scarlet flowers, and its deep-green foliage, rendering the plant one of the most showy and attractive objects of the garden.
Though inferior to some of the finer sorts of garden-beans, its value as an esculent has not been generally appreciated. The young pods are tender and well flavored; and the seeds, green or ripe, are much esteemed in many localities. "In Britain, the green pods only are used; on the Continent, the ripened seeds are as much an object of culture; in Holland, the Runners are grown in every cottage-garden for both purposes; while, in France and Switzerland, they are grown chiefly for the ripened seeds. In England, they occupy a place in most cottage-gardens, and are made both ornamental and useful. They cover arbors, are trained over pales and up the walls of cottages, which they enliven by the brightness of their blossoms; while every day produces a supply of wholesome and nutritious food for the owner. The French, now enthusiastically fond of this legume, at one time held it in utter detestation."
Painted Lady-Runner.
A sub-variety of the Scarlet-runner, with variegated flowers; the upper petals being scarlet, the lower white. The ripe seeds are paler, and the spots and markings duller. Cultivation and uses the same.
White-Runner.
A variety of the Scarlet-runner. The plants are less vigorous, the pods are longer and less wrinkled, and the flowers and seeds pure white.
The green pods are used in the same manner as those of the Scarlet-runner, and are similar in texture and flavor; but the shelled-beans, either green or ripe, are generally considered superior to those of the Scarlet variety. They are sometimes seen in vegetable markets under the name of the "Lima;" and are probably often cultivated, as well as purchased and consumed, as the Lima. The White-runner beans, however, are easily distinguished by their greater thickness, more rounded form, and especially by their uniform whiteness.
