Definition of philadelphus in English:



  • A mock orange.

    • ‘It's kind of, well, just a slabbed area at the moment, but I have a plan to make it into a small courtyard garden, in green and white. I see white clematis, hostas, a scented philadelphus, pots of white lilies, maybe a white climbing rose.’
    • ‘There are drifts of feverfew, clouds of philadelphus, grasses whispering in the breeze, and everywhere the perfume of 1,000 blossoms keeping the countryside alive in the heart of London.’
    • ‘Mock orange, or philadelphus, prefers an organically enriched, moist, well-draining soil and filtered sun.’


Late 18th century: modern Latin (adopted by Linnaeus as a genus name), from Greek philadelphos loving one's brother.
