The palest of shell pink buds open to white flowers on this medium-sized, semi-evergreen rhododendron with small to medium-sized leaves. Rhododendrons have a tough time of it in most Chicago gardens. Typically, the soils are alkaline clay, which are not ideal, and snow cover to buffer the coldest temperatures in winter is not always available. 'Pillow Party' is one of the few that reliably survive, despite all of the odds stacked against it. From late April to early May, the plants are covered with masses of small to medium-sized white flowers. Ideally, plant in acidic, well-drained, moisture-retentive soils in partial shaded locations, and site in the garden to avoid, if possible, cold, dry winter winds.
