It grows to heights between 1 and 2 meters. Research is ongoing into its ancestry among wild "Nicotiana" species, but it is believed to be a hybrid of "Nicotiana sylvestris", "Nicotiana tomentosiformis", and possibly "Nicotiana otophora".

Nicotiana benthamiana the north coast of Australia by Benjamin Bynoe on a voyage of in 1837. A synonym for this species is "Nicotiana suaveolens" var.

This was transferred to "Nicotiana benthamiana" by Karel Domin in "Bibliotheca Botanica" (1929), retaining the author's name in the specific epithet. "Nicotiana benthamiana" is considered by a growing scientific community as a model organism for performing plant research. For example, the leaves are rather frail and can be injured in experiments to study ethylene synthesis. Ethylene is a plant hormone which is secreted, among other
