Nova Zembla Rhododendron

Trusses of deep, true-red blooms in mid-to-late spring on one of the hardiest, most dependable rhododendrons you can grow.

Nova Zembla (Rhododendron x 'Nova Zembla') is a broadleaf evergreen shrub prized for its bold spring display: rounded clusters of ruby-red, funnel-shaped flowers, each marked with a darker burgundy blotch at the throat, set against glossy, dark green foliage that holds through winter. It builds into a dense, rounded mound roughly 5 feet tall and 5 feet wide at maturity, with a moderate, well-behaved growth rate. The classic upright trusses and leathery leaves give it a polished, structural look every season of the year, not just while it blooms.

Why growers choose the Nova Zembla

• Striking red bloom. Few rhododendrons deliver a red this saturated and even; the spring trusses are large, full, and stand out against the dark foliage.
• Cold-hardy and tough. Reliable down to zone 4, it shrugs off harsh winters that defeat many broadleaf evergreens, making it a go-to for northern gardens.
• Year-round structure. The deep green, leathery leaves are evergreen, giving you presence and screening value long after the flowers fade.
• Pollinator draw. The spring trusses attract bees and butterflies, with hummingbirds working the flowers during peak bloom.
• Dependable and adaptable. A proven, vigorous cultivar that performs well in full to part sun and rewards minimal care with a consistent show.

It earns its place as a foundation anchor, a flowering evergreen hedge or screen, or a focal point in a woodland-edge or mixed shrub border, and pairs naturally with other acid-lovers like azaleas, pieris, and ferns for a layered, four-season planting.
