What does bignonia mean?
Bignonia refers to any member of Bignonia, a genus of woody climbing plants native mainly to tropical and subtropical regions of the Americas. These vigorous climbers are best known for their showy, trumpet-shaped flowers, often in shades of orange or red, which make them popular ornamentals on trellises, walls, and pergolas. The genus gives its name to the larger family Bignoniaceae, which includes well-known ornamental climbers such as trumpet creeper and crossvine, though modern botany has moved several former members into other genera. In practice, the word appears most often in horticultural and botanical contexts rather than casual conversation, and gardeners may use it loosely for any trumpet-flowered vine of the family. The name honors Jean-Paul Bignon, an eighteenth-century French scholar and royal librarian associated with early botanical classification, making bignonia one of many plant names derived from a person's surname rather than from any descriptive root.
nounAny of various woody climbing plants of the genus Bignonia, native chiefly to tropical and subtropical America, typically bearing trumpet-shaped flowers.
- Any woody climber of the genus Bignonia in the family Bignoniaceae, bearing trumpet-shaped flowers.

Bignonia isn't named for a flower at all — it honors Jean-Paul Bignon, an 18th-century French royal librarian who championed botanical science.

Etymology of bignonia
Bignonia is a New Latin scientific name coined in honor of Jean-Paul Bignon (1662–1743), a French ecclesiastic and librarian who served as president of the Académie Royale des Sciences and supported botanical work. Like many Linnaean-style genus names, it derives from a person's surname rather than a classical root, so it has no cognates in the ordinary etymological sense beyond other terms built on the same name, such as the family name Bignoniaceae. The English word entered use as the botanical name itself, adopted directly from scientific Latin.

How bignonia is actually used
Primarily a botanical and horticultural term, used in gardening writing and formal descriptions of plants rather than everyday speech. In loose garden usage it sometimes extends to closely related trumpet-flowered climbers such as crossvine, though botanically these belong to separate genera within the same family.
