Description
The Common Rasp Fern (Blechnum medium, syn. Doodia media) is a hardy, evergreen fern originating from the subtropical rainforests of Australia. It features unique fronds that emerge pink or reddish before maturing to a deep green, providing a striking contrast. With its dense, upright growth, this fern is an excellent choice for shaded garden beds, under-planting, or as an indoor potted feature in a humid environment.
Best grown in well-draining, moist soil, the Common Rasp Fern thrives in areas with part to full shade. It benefits from regular watering, especially in Perth’s drier months, to maintain its lush foliage. Mulching around the base helps retain moisture, while occasional feeding with a balanced, organic fertiliser will promote robust growth. This fern is an excellent low-maintenance choice for adding year-round greenery to shaded spaces.
