Angiopteris evecta (king fern).
Angiopteris evecta is often cultivated as an ornamental in gardens, parks, and botanical gardens for its large rhizomes and gigantic fronds. It has repeatedly escaped from cultivation and has the potential to easily colonize new ecosystems. It is currently listed as invasive in Hawaii, Jamaica and Costa Rica where it can be found naturalized and spreading mostly in wet valleys and on slopes in montane and lowland rainforests. In Cuba it is considered an invasive species with the potential to "transform" natural ecosystems.
