Lewis' mock-orange, Philadelphus lewisii

Lewis' Mock-Orange, or Philadelphus lewisii, is a deciduous shrub native to western North America, celebrated for its fragrant, white, citrus-like flowers. This plant is not only the state flower of Idaho but also an important species for wildlife, offering thermal and security cover. It can spread both vegetatively and through seeds, forming seedbanks within the top layer of the soil. Remarkably adapted to fire-prone areas, it can resprout from rhizomes and root crowns after being top-killed by fires, making it a resilient addition to landscapes that experience frequent wildfires.

The shrub's versatility extends to human uses as well, with Native American tribes utilizing its hard wood for various tools and its leaves and bark as a mild soap due to their saponin content. The flowers have also been used in perfumes and teas. For gardeners, Lewis' mock-orange is an attractive choice due to its drought tolerance, ability to grow in poor soils, and suitability for xeriscaping. It's known for its dazzling flowers and fruity scent, adding a touch of beauty and fragrance to any garden space.

In the wild, this species can be found from southern British Columbia to central California, and eastward to Idaho and Montana. It exhibits considerable variability in its physical characteristics depending on its habitat, with plants in dryer areas often having smaller, more oval-shaped leaves. The shrub typically grows between 4.5 to 9 feet tall and is favored in gardens for its aromatic white flowers, which resemble orange blossoms and can bloom from May through July. The plant's wood has been used historically for various implements, and its parts that are rich in saponins were traditionally used as a cleansing agent.
