About Rustyback fern
Asplenium ceterach, commonly known as Rustyback or Scaly Spleenwort, is a small, perennial fern characterized by its leathery, lobed fronds with undersides covered in rust-colored scales. It's an excellent choice for rock gardens, stone walls, or as an indoor plant in terrariums, where its unique texture can be admired.
Native range
Europe, North Africa, and Western Asia
Care tips
This fern thrives in bright indirect light or partial shade; direct sunlight can scorch its fronds. It's drought-tolerant once established but appreciates moderate watering when the substrate is dry to the touch, avoiding waterlogging. It requires a well-draining, preferably alkaline to neutral substrate with good aeration. A common mistake is overwatering, which can lead to root rot.
