The flowers of Hydrangea paniculata 'Unique' unfold on 8-inch-long flower spikes, broad at the base, and rounded at the tip. Its blooms open white, and with age, will turn pinkish white in fall, drying to tan in winter. This hardy shrub can get large over time—to 10 feet in height and width. It is well adapted to grow well in full sun and partially shaded conditions. Keep Unique uniformly moist during the growing season for maximum flower production.
