Factors to Consider When Choosing a Nandina Variety
Choosing the right Nandina depends on your regional climate, soil conditions, and landscape goals. Understanding these factors helps ensure healthy growth and vibrant displays throughout the year.
Climate Compatibility
Most Nandina varieties thrive in USDA zones 6 through 9. However, some, like Nandina ‘Gulf Stream’, are more tolerant of colder temperatures, making them suitable for zones 5 and 6.
Soil and Light Requirements
Nandina prefers well-drained soil with moderate moisture. It can tolerate full sun to partial shade, but variegated varieties may require more shade to prevent leaf scorch.
Regional Considerations
Climatic conditions influence which Nandina variety will perform best in your area. For example, in colder regions, selecting a hardy variety like Nandina ‘Gulf Stream’ ensures better survival and color retention.
Cold Climates
In regions with harsh winters, choose Nandina varieties known for cold tolerance. Mulching around the base can also protect roots from freezing temperatures.
Warm and Humid Regions
In warmer climates, Nandina’s heat tolerance allows for vibrant foliage and berries. Ensure adequate watering during dry periods to maintain plant health.

Proper planting and maintenance are key to establishing healthy Nandina plants. Follow these tips for optimal growth:
- Choose a location with suitable sunlight and soil conditions.
- Plant in spring or early fall for best establishment.
