學名：Davallia griffithiana Hook.
英名：Rabbit's foot Fern
A perennial herb in the genus Davallia, widely distributed in subtropical and tropical regions from South Asia to East Asia, creeping on rocks or tree trunks. Rhizomes decumbent and climbing by adventitious roots, coated with silvery white scales. Fronds 10-15 cm long, triangular or pentagonal, tri- or quad-pinnately compound; small pinnae lanceolate or long ovate. Sori embedded in a dent on the surface of fertile fronds and covered with a cup-shaped indusium. Fronds exfoliate occasionally during dry winter.
The plant grows well in a warm environment with partial sun and can be grown as an epiphyte on trees or in well-drained medium. It defoliates and goes dormancy after prolonged drought and thrives faster in high humidity. Cut water use in cold seasons and increase watering in other seasons to promote the growth. Propagated from ramets.
It’s known as "rabbit's foot" fern in the market because the silvery white villi at the end of stolons look like a rabbit's foot. With delicate fronds, it can be appreciated in a single pot, a mixed planter and a hanging basket, or fixed directly on a tree trunk to display the feel of wilderness.
