Bring classic mockorange fragrance to your garden with Philadelphus 'Buckley's Quill'. This deciduous shrub forms an upright, compact plant and produces tight clusters of double white flowers with distinctive quill-like petals in late spring to early summer. The blooms are showy and strongly fragrant, making it an excellent choice near patios, walkways, and open windows where you can enjoy the scent.
Plan for a mature size around 60-72 inches tall and about 36-48 inches wide. Use it as a specimen, in mixed shrub borders, or massed for a seasonal flowering display. It pairs well with other spring and early-summer bloomers and provides a fresh green backdrop after flowering ends.
For best performance, plant in full sun to part shade (more sun generally means more flowers). Choose moist, well-drained soil; average garden soil is typically fine as long as drainage is decent. Water regularly during establishment, then provide supplemental watering during prolonged dry spells, especially in hot, exposed sites.
Pruning is simple: shape and thin immediately after flowering so you do not remove next year’s flower buds. Remove a few of the oldest stems at the base over time to keep the shrub vigorous and flowering well. Mulch to conserve moisture and moderate soil temperatures, keeping mulch a few inches away from the stems.
