Philadelphus lewisii is a rounded shrub 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. (Wikipedia) Photo credit: Oceanflynn – Own work, CC BY-SA 4.0.
