Family: Lomariopsidaceae

Kupukupu is a robust fern native to Hawaiʻi. The stiff or slightly drooping fronds grow to 2 feet maximum but usually are shorter. Kupukupu grows beautifully in containers or in the ground. Plant them in groups or mixed among other plants. Ensure the fern has good drainage; waterlogging will kill the plant. However, they don’t do well indoors unless it has bright sunlight and supplemental light. 

Kupukupu looks very similar to the non-native swordfern, Nephrolepis exaltata. They often hybridize together. Kupukupu’s most distinguishing characteristic is beneath the surface. Essentially, tubers develop on the fern stolons, which can be used for food storage or reproduction of new ferns.
