Polarnacht Rhododendron

Rhododendron x 'Polarnacht' (H-3)

Polarnacht, translated from German, means Polar Night. Strikingly dark purple flowers with wavy margins and a deep red spotting that bloom late May to early June. Produces dark green foliage with a dense, compact habit 3 ft. tall by 6 ft. wide. We love the very dark distinctive color. An excellent foundation plant or low hedge due to its smaller, compact habit. Evergreen.
