Partially. Rhododendron catawbiense is native to the Appalachian Mountains in the southeastern United States. ‘Nova Zembla’ is a hybrid cultivar of this species, bred for enhanced cold hardiness and vivid bloom color. While not a straight native, it retains some ecological value and is suitable for native-inspired or woodland gardens.

‘Nova Zembla’ is prized for its large, vivid red to deep pink flower trusses with darker throats, blooming in mid to late spring. It has a dense, rounded growth habit, typically growing 6 to 8 feet tall and wide, and features leathery evergreen foliage for year-round presence in the landscape.

‘Nova Zembla’ performs best in partial shade and prefers cool, moist, acidic, well-drained soils rich in organic matter. It is hardy in USDA zones 4 through 8 and benefits from mulching, regular watering, and protection from drying winds and hot afternoon sun, especially in warmer climates.

Yes, to a degree. The spring flowers attract native bees, bumblebees, and hummingbirds, providing nectar early in the season. However, as a hybrid cultivar, it offers less value as a host plant than straight native shrubs, and is best used in combination with other native species for ecological balance.

Rhododendron catawbiense and its cultivars are moderately deer-resistant, though new growth and flower buds may be browsed in areas with high deer pressure. ‘Nova Zembla’ is generally low-maintenance if grown in suitable conditions. Prune only after flowering if needed, and keep soil consistently moist but well-drained.
