KEZI In The Garden – Ferns for All Seasons

“Ferns for All Seasons: Evergreen and Deciduous Varieties in the Pacific Northwest”-Air Date 8/31

Sometimes it is hard to tell what kind of fern you should get for your garden beds, container, or property because there are so many different types out there. How big do they get and do they keep their fronds or die back in the winter are questions you might wonder when looking at ferns. Here is some helpful information that can help you decide what fern might best suit your area.

 

Evergreen ferns in the Pacific Northwest:

1. Deer Fern (Blechnum spicant): 1-2 feet in height and spread.

2. Autum Fern & Wood Fern (Dryopteris) 1.5-2 ft in height and spread

3. Western Sword Fern (Polystichum minutum): 2-2.5 feet in height and spread.

4. Tassel Fern (Polystichum polyblepharum): slowly grows to 2 feet in height and spread.

5. Christmas Fern (Polystichum acrostichoides): 2-3 feet in height and spread

6. Holly Fern (Crytomium) 2-2.5-3 feet in height and spread

 

Deciduous (dies back in winter) ferns in the Pacific Northwest:

1. Maidenhair Fern (Adiantum): 1-2 feet in height and spread.

2. Sensitive Fern (Onoclea Sensibilis) 2-3 ft in height and spread

3. Lady Ferns (Athyrium): 2-3 feet in height and spread.

4. Ostrich Fern (Matteuccia struthiopteris) 3-3 feet in height and spread

5. Male Fern (Dryopteris Filix-max) 3-4 ft in height and spread

 

Each type of fern has unique foliage that can be quite impactful when paired with other plants or planted in mass in your garden. Knowing the size and whether the fern is sticking around for the winter months or dying back to the ground can really help guide you choice and placement.

 

One final tip is that many evergreen ferns can benefit from pruning some or all of the older fronds in late winter/early spring as the new fronds start to emerge. Pruning the old fronds will give more room to the showier new growth.
