context_page_description: Philadelphus lewisii —also known as Gordon's mockorange, Indian arrowwood, wild mockorange and syringa—a name that usually refers to the unrelated lilacs.—is a deciduous shrub native to western North America, from northwestern California in the Sierra Nevada, north to southern British Columbia, and east to Idaho and Montana. It was first collected by scientist and explorer Meriwether Lewis in 1806 during the Lewis and Clark expedition and the Philadelphus lewisii is named after him.
context_section_description: The shrub is rounded and grows to 1.5–3 metres (4 ft 11 in–9 ft 10 in) in height. It sends out long stems which are red when new and fade to gray with age, the bark shredding in small flakes. The oppositely arranged leaves vary in size across individual plants but they are usually oval, 3–5 centimetres (1.2–2.0 in) long, smooth or serrated along the edges, and light green in color with a rough texture. The flowers are produced in clusters at the ends of long stems, with four white petals up to 4 centimetres (1.6 in) long and numerous yellow stamens. At the height of flowering, the plant is covered in a mass of blossoms. The flowers have a heavy, sweet scent similar to orange blossoms with a hint of pineapple. The fruit is a small hard capsule about a centimeter long with woody, pointed wings, containing many brown seeds. It is hardy from USDA zones 3 to 9.
