Family: Lomariopsidaceae

Kupukupu is a robust fern native to Hawaii. 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 nonnative sword fern, N. exaltata. They often hybridize together. The most distinguishing characteristic is beneath the surface. Tubers that develop on stolons, the tubers store food, and new ferns can develop from them.
