Buddleja, or Buddleia ( /ˈbʌdliːə/) commonly known as the butterfly bush, is a genus of flowering plants. The generic name bestowed by Linnaeus posthumously honoured the Reverend Adam Buddle (1662–1715), a botanist and rector in Essex, England, at the suggestion of Dr. William Houstoun. Houstoun sent the first plants to become known to science as buddleja (B. americana) to England from the Caribbean about 15 years after Buddle's death.
