Littleleaf Mockorange 'Desert Snow' (Philadelphus microphyllus) is a selected form of the native Mockorange introduced by High Country Gardens. This beauty sports very large and fragrant flowers compared to the straight species and is an excellent choice for smaller garden areas or yards due to its medium size. The foliage turns yellow in the fall. Add Littleleaf Mockorange to garden beds or borders, foundation plantings, the edges of woodland or shade gardens, or use as an informal hedge. It is somewhat tolerant of urban pollution.
