Hi everyone, Ferb Vu here! Today, we’re diving deep into the world of a fantastic shade-loving fern: Dryopteris Intermedia, also known as the Intermediate Wood Fern. This North American native adds a touch of elegance and lushness to any shady corner.

Whether you’re a seasoned plant enthusiast or a curious beginner, I’m here to answer all your burning questions about this fascinating fern. So, grab a cup of tea, settle in, and let’s get schooled on Dryopteris Intermedia!

What Makes Dryopteris Intermedia Special?

Dryopteris Intermedia is an evergreen fern, meaning it keeps its beautiful green fronds year-round. These fronds, reaching up to 3 feet tall, are a sight to behold. They’re lacy and intricate, with deeply divided leaflets that dance in the breeze.

Thrives in the Shade: Unlike many flowering plants that crave sunshine, Dryopteris Intermedia flourishes in shady areas. This makes it a perfect choice for north-facing gardens or spots under trees where other plants struggle.

Low Maintenance: This fern isn’t fussy. It requires minimal care, making it ideal for busy gardeners. Just provide it with the right conditions, and it’ll reward you with lush, green foliage season after season.

Native Beauty: As a North American native, Dryopteris Intermedia plays a vital role in the local ecosystem. It provides habitat for beneficial insects and adds a touch of natural elegance to your garden.

Planting and Caring for Dryopteris Intermedia


  • Look for a spot with dappled sunlight or partial shade. Avoid full sun, as it can scorch the fronds.
  • Ensure well-drained soil. Rich, moist soil amended with compost is ideal.
  • Dig a hole slightly larger than the root ball and gently place the fern inside. Backfill the hole and water thoroughly.


  • Water regularly, especially during hot and dry periods. Aim for consistently moist soil but avoid waterlogging.
  • Mulch around the base of the fern to retain moisture and suppress weeds.
  • Fertilize sparingly with a balanced fertilizer in early spring.
  • Remove any dead or damaged fronds to maintain a neat appearance.
