Among the best indoor ferns is a staghorn fern, an indoor plant with blue-green foliage of unusual shape - reminiscent of forked antlers - which arches in an elegant way.
In its natural environment staghorn ferns, or Platycerium bifurcatum, are found in the tropical forests of Africa, Australia and Southeast Asia. However, they don't grow like the other ferns you may know.
'Staghorn ferns are epiphytes. That is, they attach themselves to other plants in the wild,' says Julia Omelchenko, botany expert for the Plantum app.
These unusual houseplants grow on the trunks and branches of trees, among other plants, in their natural environment. They don't gain nutrients from soil but rather from the air and the plants they are growing on.
And that isn't the only interesting thing about them; staghorn ferns have two types of fronds - sterile and fertile.
'Hard, round sterile fronds grow at the plant’s base, serving primarily to protect the roots and facilitate water and nutrient absorption. Sterile fronds remain green in fall and turn yellow and dry in spring and summer. It's important not to remove these leaves, as they provide essential nutrition to the roots,' Julia says.
'Big, impressive-looking fertile fronds are responsible for the plant's name, as they resemble the antlers of a stag. These fronds play a crucial role in reproduction, featuring brown spores, also known as sporangia, on their undersides,' she adds
Outdoors, staghorn ferns thrive in US hardiness zones 9-12 but they are also highly popular as indoor plants to add leafy interest with their large, arching foliage.
There are a few things you need to keep in mind when caring for a staghorn fern indoors and we've compiled expert tips so that you can do it successfully.
5 expert tips for staghorn fern care
If houseplants with a quirky touch are your thing, a staghorn fern is certainly one to consider. This epiphytic plant is commonly grown indoors and can add a tropical and elegant feel to your interiors. We've asked experts how to best care for these ferns indoors.
1. Avoid direct sunlight
In its natural habitat, staghorn ferns are protected from direct sunlight by canopies of trees in tropical rainforests. Therefore, it is best to replicate this in the home with filtered light.
'Staghorn ferns thrive when exposed to bright but indirect light, receiving four to seven hours of dappled sunlight daily,' says Autumn Hilliard-Knapp, houseplant expert from Perfect Plants.
'To provide the best light conditions, it's recommended to place them near a north or east-facing window or in a location with filtered or indirect light,' she adds.
It's best to avoid direct sunlight with these plants because it could scorch or discolor their iconic leaves, but take care to ensure they are still in a position with sufficient light levels.
'A lack of light will cause stunted growth and cease spore formation,' says Julia Omelchenko.

2. Use lighter soil
Because these plants don't usually grow in soil, it's important to keep them in a well-draining, light potting mix in the home.
'A common mixture is equal parts of peat moss, perlite, and coarse-grained sand, adding some orchid bark for extra drainage and retention of nutrient,' says Autumn.
'Because staghorn fern naturally grows on trees, avoid using garden soil or heavy clay as it will not facilitate proper drainage, leading to root rot and eventual death of the plant,' she adds.
There are already lots of potting mixes on the market that would provide staghorn ferns with the right growing conditions, like this organic sphagnum peat moss from Perfect Plants.
3. Water regularly
It's easy to keep staghorn ferns at a happy water level by putting a regular watering schedule in place.
Using a top watering method with a watering can, like this watering can from Bloomscape, you can expect to water your staghorn fern every week or every couple of weeks.
'The frequency of watering depends on factors like humidity, light, and temperature. It's crucial to water thoroughly, allowing water to flow through the growing medium and out the drainage holes. However, ensure that the plant is not left standing in excess water,' says Autumn.
You can quickly check if your staghorn fern needs watering by feeling if the top inch of soil is dry.
4. Keep humidity high
Like other tropical indoor plants and ferns, staghorn ferns benefit from high humidity and moisture.
'These plants also absorb water through their fronds and roots. Periodic misting or a gentle shower can provide additional moisture,' says Autumn.
Using something like this mister from Greendigs you can give your fern a daily misting, holding it far enough away that you aren't oversaturating the foliage.
'It's usually sold attached to a stake, which makes it easy to water the plant by soaking it along with the stake in water for five to ten minutes,' says Julia. Keeping the stake moist will increase humidity among the fronds.
Other ways to increase humidity include moving houseplants close together or using a pebble tray like this humidity tray from Amazon.
5. Elevate staghorn ferns
If the funky foliage of staghorn ferns isn't enough on its own and you're looking for more ways to uplift your interiors, why not turn it into a hanging plant?
'Experienced gardeners grow Platycerium bifurcatum as a hanging plant attached to a bark or wooden stake, with moss, peat, or coir serving as a medium between the stake and the plant,' says Julie.
Staghorn ferns are also popular options for kokedama, a Japanese technique for hanging plants in moss balls.
'Hanging staghorn ferns can create a beautiful display and mimic their natural growth habit in the wild,' says Autumn.
