Description & Care Instructions:

This relatively new Australian fern grows uniquely shaped leaves with a waxy coating that prevents water loss and shedding. This durability and adaptability make it an ideal indoor plant (and gift) for any collection in any climate. It also does not produce spores, which can be a bit messy. It is a medium-sized plant that grows flat and works well for hanging pots or pedestals.



Provide your Austral Gem Fern with medium to bright lighting. Place it near a sunny window but not directly in the sun. This plant can tolerate less light as well as artificial light.



Water when the soil feels dry. This plant can tolerate somewhat drier conditions due to its waxy leaves. If the soil is dried out water thoroughly but do not let the soil become soggy. The amount of watering needed will depend on the size of the pot as well as the lighting and temperature. Warmer, brighter environments may require more watering. Larger pots may require less watering. Remember to check on your plants often until you learn what works best for your situation.


Temp & Humidity:

This fern will fare well in average home and humidity temperatures. However, you will want to keep it away from cold drafts such as those from A/C vents or drafty windows. Be cautious about placing your plant in or near a bright sunny window as the heat from the glass could cause your plant to wilt or die.



Use a quality, well-draining potting mix. Austral Gem Ferns prefer a rich, more acidic soil. However, these plants will still grow in a quality, commercial potting mix.



Fertilize during the Spring and Summer months (April to September). Use a houseplant fertilizer once a month and dilute to half strength. Cease fertilizing in the Fall and Winter months as the plants are no longer growing. Too much fertilizer can cause the leaf tips to brown.
