The genus Philadelphus is comprised of about 65 plants. The native habitat of Philadelphus Mock Orange stretches across North America, parts of Europe, Northern Asia, and Japan. The plant’s historic nostalgia has been forever written into the lore of the American West by the famous Lewis and Clark Expedition. The explorer Meriwether Lewis gathered samples of the intoxicatingly fragrant bush during the return leg of his journey through Idaho and Montana in 1806. The plants he gathered were dubbed the Philadelphus lewissi in his honour.

Philadelphus Mock Orange shrubs vary in size and some leaf structure. However, these showy plants all have one thing in common — they all produce an abundance of eye-catching white or yellow petaled flowers with bright yellow stamens that possess a heady aroma.

Carl Linnaeus, the Swedish botanist, physician, and zoologist, chose to call the plant genus ‘Philadelphus’, a word that loosely translates as ‘extreme’, because of the strong, intoxicating fragrance of the flowers of this deciduous shrub. One flower can easily fill an entire room with its sweet perfume. Many refer to the Philadelphus shrubs as ‘Mock Oranges’ because the flower’s scent is similar to that of an orange tree in full bloom but more pronounced and a bit sweeter. The shrub’s blossoms draw an abundance of butterflies and bees to the garden. In the morning and early evening hours, one shrub can fill the entire garden with its sweet, relaxing scent.
