Botanical name: Davallia canariensis
Hare's Foot Fern is grown for its thick, scaly rhizomes which grow over the edge of the pot and resemble a hare's foot hence giving the fern its common name. The rhizomes absorb moisture and nutients as they crawl. The fronds are broad, finely divided and look like carrot tops. It grows to a height of about 1.5 ft and about 2 ft wide. Hare's Foot Fern is ideal for a hanging basket where the rhizomes can hang freely for maximum display. The rhizomes should not be buried under the soil as it encourages rotting.
Hare's Foot Fern is found from west Mediterranean to the Atlantic Islands where it grows in a sunny atmosphere and amongst rocks. The species name canariensis suggests that this fern has its origins in the Canary Islands. Hare's Foot Fern is related to the larger but less hardy Davallia fejeensis (Rabbit's Foot Fern), Davallia bullata (Squirrel's Foot Fern) and Davallia trichomanoides (Black Rabbit's Foot Fern).
