Antler-like fronds give staghorn fern its common name. It's also known as elkhorn fern. Staghorns grow as epiphytes in tropical Australia, growing on tree trunks.
This stag horn fern actually has 2 types of fronds. Those at the base of the plant are flat, round and light green, turning brown as they age. Epiphytes in their native habitats, staghorn ferns cling to tree trunks taking in nutrients from fallen leaves and other debris that gets trapped behind these slightly curved fronds.
The second type of fronds grow from the round fronds and can reach up to 3 ft (90 cm) long. These deeply lobed fronds resemble staghorn deer antlers.
You can keep your young plant in a pot, but eventually the round fronds will cover the growing medium making it difficult to water from the top. Don't saturate these fronds with water because they'll rot easily. Water pots from below by setting pot in a tray of water for 15 minutes.
Transplanting. When your fern grows bigger, you may want to hang it in a sphagnum moss-lined wire basket or mount it on tree bark or a slab of wood, which is closer to how these ferns grow in their native habitat.
Mounting staghorn fern. Place a few handfuls of damp sphagnum moss or orchid mix on a piece of bark or (untreated) wood board. Place the fern over the mound of medium, so that the flat, round basal fronds are touching the board. Use twine, wire or fishing line to firmly hold the fern to the board.
