Below, I’ll answer some of the most frequently asked questions about Philadelphus Lewisii, including how to care for it, its pronunciation, and more.
What is Philadelphus Lewisii?
Philadelphus Lewisii is a deciduous shrub known for its stunning white, four-petaled flowers and delightful fragrance, often reminiscent of oranges, which is how it earned the common name “Mockorange.” This plant can grow up to 10 feet tall and 6 feet wide, making it an excellent choice for hedges or as a standalone specimen in the garden. It’s not only beautiful but also hardy, withstanding a range of climates and growing conditions.

The pronunciation of Philadelphus Lewisii can seem a bit tricky at first. It is pronounced as “fill-uh-DEL-fus loo-ISS-ee-eye.” Breaking it down into syllables can make it easier to get right. The name is derived from the Greek word “philos” meaning loving, and “adelphos” meaning brother, which refers to the close stamens found in the flowers.
How to Care for Philadelphus Lewisii (Blizzard Mockorange)?
Caring for Philadelphus Lewisii is relatively straightforward, which is one of the reasons I love having it in my garden. Here are some tips:
- Sunlight: Philadelphus Lewisii thrives best in full sun to partial shade. It needs at least 6 hours of direct sunlight daily to bloom profusely.
- Soil: This shrub prefers well-drained soil but is adaptable to different soil types, including sandy or loamy soils. Adding organic matter can improve soil quality.
- Watering: Water the plant regularly during the first growing season to establish a deep, extensive root system. Once established, it is drought-tolerant but performs best with moderate watering, especially during dry periods.
- Fertilization: Philadelphus Lewisii does not require much fertilization. A balanced, slow-release fertilizer in the spring can boost growth and flowering.
- Mulching: Adding a layer of mulch around the base of the plant can help retain moisture and regulate soil temperature.
How to Prune Philadelphus Lewisii?
Pruning is an essential part of maintaining a healthy and aesthetically pleasing Philadelphus Lewisii. Prune immediately after flowering to avoid cutting off next year’s flower buds. Focus on removing dead or diseased wood, and thin out the oldest stems to encourage new growth. I like to shape the plant by cutting back overgrown branches, which also helps to improve air circulation and sunlight penetration.
What Does Philadelphus Lewisii Look Like in the Winter?
In the winter, Philadelphus Lewisii loses its leaves, revealing its grayish-brown stems and branches. Although it is not as visually striking without its lush foliage and flowers, the structure of the bare branches can add an interesting texture to the winter garden. The plant remains dormant during this period, conserving energy for the blooming season.
Where Can You Buy Philadelphus Lewisii?
Philadelphus Lewisii is widely available at local nurseries, garden centers, and online plant retailers. I’ve found it helpful to check with native plant nurseries, as they often carry a good selection of Philadelphus Lewisii varieties.

The Mockorange’s lovely blooms symbolize the natural beauty of Idaho’s landscapes.
