Ruby Rasp Fern is an attractive and hardy Australian native fern known as Doodia aspera, featuring delicate, lacy fronds with a distinctive reddish-brown colour on the underside. It grows up to 1m tall, making it ideal for shaded or woodland garden areas. Rasp Fern thrives in well-drained, moist soil and prefers part to full shade, adding a fine-textured element to garden beds and borders.
