About the genus
Buddleja is a genus comprising over 140 species of flowering plants endemic to Asia, Africa, and the Americas. The generic name bestowed by Linnaeus posthumously honoured Adam Buddle (1662–1715), an English botanist and rector, at the suggestion of William Houstoun. Houstoun sent the first plants to become known to science as buddleja to England from the Caribbean about 15 years after Buddle's death.
