TECOMA GRANDIFLORA (syn Bignonia grandiflora), from China and Japan (1800), is not so hardy as T. radicans, although in certain maritime districts it succeeds fairly well. The flowers are very attractive, being of a rich orange-scarlet, and produced in drooping clusters. Both foliage and flowers are larger than those of T. radicans. It wants a warm, sunny wall, and light, rich, and well-drained soil, and if only for its lovely flowers, it is well worthy of coddling and good treatment.
T. RADICANS (syn Bignonia radicans).—Trumpet Flower. North America, 1640. An old occupant of our gardens and one of the most beautiful wall plants in cultivation. It is a tall climber, of sometimes fully 20 feet in height, with graceful pinnate leaves, and handsome trumpet-shaped scarlet-red flowers, that are at their best about mid-summer, though the period of flowering extends over a considerable length of time. The stems are long, twisted, and wiry, and like those of the Ivy send out roots at the joints and so fasten the plant in position. Few climbing plants are more attractive than the Trumpet Flower, and being hardy in most parts of the country, and free of growth, is to be recommended for covering walls, and arches, or similar structures. T. radicans major is of more robust growth than the species, with larger foliage and paler flowers. The orange-scarlet flowers are produced in terminal corymbs.
