Philadelphus pubescens (Hoary Mock Orange)

Philadelphus pubescens (Hoary Mock Orange) is a dense, multi-stemmed, deciduous shrub of upright habit. In late spring to midsummer, it boasts a profusion of mildly fragrant, 4-petaled, white flowers, 2 in. across (5 cm), adorned with a bouquet of yellow stamens. At the height of flowering, the shrub is literally covered in a mass of blossoms. Borne in clusters of 3-9 blossoms, they attract bees and other pollinators.
