Lewis's mock orange is a tough, low-maintenance deciduous shrub that thrives in partial shade to full sun with average moisture. Plant it in well-drained soil and water regularly during its first season to establish deep roots. Once established, it is quite drought-adaptable and rewards you each spring with intensely fragrant white blossoms.
