Among our earliest exports, this hardy shrub, the Swamp Azalea, and the superb flame-colored species of the Alleghanies, were sent early in the eighteenth century to the old country, and there crossed with A. Pontica of southern Europe by the Belgian horticulturists, to whom we owe the Ghent azaleas, the final triumphs of the Hybridizer, that glorify the shrubberies on our own lawns to-day.
