Hydrangea paniculata ‘Polar Bear’ produces dense, conical flower heads of lime green that turn glistening white in late summer. By autumn the blooms have transformed to a dusky shade of pink. The large flower heads make a magnificent feature and can be cut for dried arrangements. This hardy, deciduous shrub is cloaked in pointed, toothed green leaves. Paniculate hydrangeas are very easy to grow, needing very little aftercare and making a superb addition to mixed borders and woodland gardens.
