Introduction to Mock Oranges
Mock oranges are part of the Philadelphus genus, comprising approximately 60 species of flowering plants. These deciduous shrubs are native to North America, Central America, and Asia, preferring well-drained soil and full sun to partial shade. The common name “mock orange” stems from the plant’s white, fragrant flowers, which closely resemble those of the orange tree (Citrus sinensis), despite belonging to different taxonomic groups. The Philadelphus coronarius, or sweet mock orange, is one of the most popular species due to its robust growth and exceptionally fragrant blooms.
