Why Choose Anderson’s Hollyfern for Your Garden?
There are several compelling reasons to consider adding this native fern to your landscape:

Ideal Growing Conditions
Anderson’s hollyfern is happiest when you can replicate its natural woodland habitat. Here’s what it needs to thrive:
- Light: Partial to full shade – avoid hot afternoon sun
- Soil: Moist, well-draining soil rich in organic matter
- Moisture: Consistent moisture is key, but avoid waterlogged conditions
- Climate: Hardy in USDA zones 4-8, perfect for cooler climates
- Humidity: Appreciates higher humidity levels typical of woodland settings
Perfect Garden Settings
This versatile fern works beautifully in several garden styles:

Planting and Care Tips
Getting Anderson’s hollyfern established is fairly straightforward if you follow these guidelines:

- Site preparation: Amend soil with compost or leaf mold for better drainage and nutrition
- Watering: Keep consistently moist but not soggy, especially during the first growing season
- Mulching: Apply a layer of organic mulch to retain moisture and suppress weeds
- Fertilizing: Generally unnecessary in rich, organic soil
- Winter care: The evergreen fronds may look a bit tattered by spring – simply trim them back to make room for new growth
A Few Things to Keep in Mind
While Anderson’s hollyfern is generally easy to grow, there are a few considerations:
- It prefers cooler, more humid conditions and may struggle in hot, dry climates
