Trumpet Vine – Campsis radicans

Tecoma is a genus of seven species of shrubs or small trees in the trumpet vine family, Bignoniaceae.^[2] They are native to the Americas, ranging from the extreme southern United States through Central America and the Antilles south through Andean South America to northern Argentina. The generic name is derived from the Nahuatl word tecomaxochitl, which was applied by the indigenous peoples of Mexico to plants with tubular flowers.^[3] Trumpetbush is a common name for plants in this genus.^[4]
