This pretty fern produces softly hairy root-like rhizomes, which as its common name suggests, look a little like a hares foot. That's why growing it in this way (perched on top of a chunk of lava) is really effective, as not only does it show off these rhizomes really well, but the fresh green fronds also look fantastic against the dark coloured stone. It will flourish in a brightly lit spot (away from direct sunlight), and as it loves high humidity, it's happiest in bathrooms or kitchens. Please keep in mind that each piece of lava will vary in shape, so it will not look exactly like the piece in the photo.
- Home care: Keep the tray three quarters full with water (ideally using filtered or rainwater to avoid the limescale turning the rock white), and make sure it does not dry out. The porous rock will then soak up the moisture, allowing the plants roots to absorb it. Misting the leaves regularly with water will help improve the humidity around the plant, and feed with a diluted liquid fertiliser (only one quarter the recommended strength), when watering from late spring to early autumn.
