Aureus Mockorange

Aureus is a golden-leaved selection of Philadelphus coronarius, grown for bright spring foliage and fragrant white flowers. Its reported mature size varies from a compact shrub to about 6 feet tall and 5 feet wide, so leave room for a broad outline and place it where the scent can be enjoyed. ## Garden use Use Aureus as a specimen or informal hedge, or group it along a border or screen. Yellow foliage is most vivid in spring and shifts toward yellow-green as the season progresses. The [University of Illinois Extension shrub guide](https://web.extension.illinois.edu/shrubselector/detail_plant.cfm?PlantID=352) identifies Aureus as the yellow-leaved cultivar of sweet mockorange, while the [University of Minnesota’s cultivar notes](https://trees.umn.edu/mock-orange-philadelphus-spp) list a compact 6-by-5-foot form with fragrant flowers. ## Growing conditions Plant in full sun or partial shade in moist, well-drained soil. In hot locations, partial shade can help protect the golden leaves from strong afternoon sun. Flowering time is described as spring by Illinois Extension and early summer by Minnesota sources, so bloom timing varies with climate. ## Maintenance Prune soon after flowering, removing older stems as needed to maintain the desired size and shape. Water during extended dry spells while the shrub establishes; established plants tolerate occasional drought. Both [Illinois Extension](https://web.extension.illinois.edu/shrubselector/detail_plant.cfm?PlantID=352) and [University of Minnesota Extension](https://trees.umn.edu/mock-orange-philadelphus-spp) provide additional culture and pruning guidance.
