Lewis' Mock-orange (Philadelphus lewisii) is a beloved native shrub known for its stunning white blossoms and heavenly citrus-like fragrance that fills the air in late spring to early summer. With its upright form and arching branches, it brings classic beauty and movement to native and water-wise gardens alike. This Utah native thrives in a variety of conditions—from mountain slopes to valley gardens—and once established, it handles dry conditions like a champ.

Not only does it add ornamental value, it’s also a magnet for pollinators like bees and butterflies, and it tends to be unbothered by deer or pests. Gardeners appreciate its reliability, fast growth, and rugged nature, especially when looking for a native plant with strong seasonal interest. Plant it as a striking specimen or in a loose hedge to enjoy its fragrant blooms and resilient charm year after year.
