B. rubra

American homes and gardens. New York V. 6 1909 Jan.-Dec. http://www.biodiversitylibrary.org/item/130750 Rubra is a well-known old sort of strong, upright growth, with plain, dark green foliage and a profusion of pendant coral-red flowers. It is almost always in bloom. The illustration of Rubra in bloom gives an idea of its decorative qualities, both as to flower and foliage. Combined with ferns, as in this instance, it is one of our best plants for the decoration of window-garden or greenhouse. Its great coral clusters, shoving against a background of green, never fail to challenge admiration; McGregor Bros. Co., catalogue Springfield, Ohio : 1912. http://www.biodiversitylibrary.org/item/186265 BEGONIA RUBRA - Dark glossy green leaves, combined with its free flowering habit. The flowers are scarlet-rose color.
