The Bignoniaceae, or Trumpet Creeper Family, is a family of flowering plants comprising about 650-750 species in 116-120 genera. Members of the family are mostly trees and lianas (Podranea and Macfadyena), shrubs and more rarely herbaceous plants. As climber plants, they are twine climbers or tendril climbers, and rarely root climbers. Most lianas are found in tribe Bignonieae, that alone contains nearly half the number of species of the family. The family and its genus Bignonia was named after Jean-Paul Bignon by his protégé Joseph Pitton de Tournefort in 1694.
Other common names for this family include jacaranda family, bignonia family or catalpa family. This family is commonly found as ornamental plants due to their large and often colorful flowers. Important members include the calabash tree (Crescentia cujete) and many genera cultivated in horticulture: Campsis, Catalpa, Jacaranda, Kigelia, Pandorea, Spathodea, and Tabebuia.
