Introducing Nova Zembla Rhododendron

Nova Zembla Rhododendron is unlike most other rhododendrons in that it can tolerate full sun, making it a unique and valuable addition to any garden. Here are some key points to keep in mind when caring for this resilient shrub:

In areas with intense afternoon sun, it is best to plant Nova Zembla Rhododendron in a spot that receives morning sun or dappled shade to prevent foliage burn.
