About Nephrolepis Cordifolia

The erect sword fern is native to the Hawaiian Islands where it is known as kupukupu, okupukupu or ni'ani'au. It has been introduced to several habitats where it has become an invasive species, such as New Zealand and Florida. To protect your local ecosystems (especially if you live in a warm, tropical climate) we suggest growing this plant only indoors. 🪴

i find it hard to keep alive, but watering it a little more often than the app suggests seems to do the trick

Picky with humidity and doesn’t like tap water. Does grow quickly and with gorgeous bright green growth. I keep mine at ~85% humidity with grow lights and spagnum moss covering the soil for extra moisture

Drinks water like a fish! Self-watering planters are a must. Lots of new growth after transplanting to SWF
