June 2014 Plant Profile: Philadelphus lewisii

June 3rd, 2014 by Soest Gardener, Riz Reyes

Philadelphus lewisii portrait 1The beginning of June boasts boisterous and abundant blooms and this native shrub is no exception. Starting in late May, an otherwise nondescript shrub begins to draw attention as masses of single white flowers suddenly begin to pop open creating a blizzard of deliciously scented clusters that cover a straggly shrub from top to bottom.

Found in open forests in low-mid elevations, Philadelphus lewisii is highly adaptable to the garden where it becomes a large shrub and requires only well-drained soil, moderate moisture, and full sun to part shade. It seems to tolerate competition from other plants very well, but requires some pruning to keep its size in check and to remove dead or non-productive  wood.

    I have yet to have anyone describe the scent of Philadelphus lewisii as deliciously scented while they are actually sniffing it. It is one of the least fragrant Philadelphus. I have heard that the subspecies native east of the Cascades more fragrant, but our westside native is disappointing in that regard. That said, I love the clean white flowers and have two in my garden. Just don’t expect to be overwhelmed by the scent!
