'Unique' bears 8-inch-long white flower heads that fade to pinkish white. It is similar to, but more vigorous than, Hydrangea paniculata 'Grandiflora'. The cultivar name refers to the shape of the flowerheads; they are broad at the base and rounded at the tip.  
Noteworthy characteristics: This is one of the most cold-hardy species. It may be grown as a single-stemmed specimen or as a multi-stemmed shrub. 
Care: Grow in moist, but well-drained soil, in sun to partial shade. Blooms on current season's wood; may cut back to a few buds from a framework in spring to produce larger flowers, or alternately, allow to grow with minimal pruning.
Propagation: Sow seed in a cold frame in spring; take softwood cuttings in early summer, hardwood cuttings in winter.
Problems: Gray mold, slugs, powdery mildew, rust, ringspot virus, leaf spots.

Love this plant! Caution though. Don't prune too late in spring (after March)as it may not bloom at all during the season. Also may take two or so years to start blooming after p[lanting a young plant. Blooms are gorgeous. Worth getting the hang of its pruning.

The white of this rose has a purity of color that is without equal. It produces semi-double, very fragrant flowers from spring to fall, which are sometimes followed by orange hips. It grows to 6 feet high and wide.
