Cheyenne Mockorange

Cheyenne® mock orange is the Plant Select selection Philadelphus lewisii 'PWY01S'. Its billowy shrub form can become somewhat vase-shaped with age, and its four-petaled white flowers have yellow centers and a citrus-like fragrance. Plant Select reports flowers in late spring, continuing sporadically into midsummer, and recommends the plant for mixed shrub borders and naturalistic landscapes. Its [official plant profile](https://plantselect.org/plant/philadelphus-lewisii-pwy01s/) lists mature size at 6–9 feet tall by 5–8 feet wide, sun or part sun, adaptable water needs, and USDA hardiness zones 3–9. The profile also notes tolerance of poor, heavy soil and dry, shaded locations. Allow room for its eventual spread, which can vary with growing conditions. Leave space for the shrub to reach its eventual spread and use it where the fragrant bloom and loose habit can be enjoyed. ## Maintenance Water while the plant establishes, then adapt irrigation to site conditions. Prune after flowering if needed to maintain size; Plant Select advises pruning once bloom has finished.
