Fishtail Palm

Fishtail palm trees feature compound leaves that reach large sizes, as does the tree itself. Each leaflet on the enormous fronds feature ragged edges that resemble the tails of fish. Whether you grow this tree indoors as a houseplant or outside on a seasonal basis (or permanently in Zones 9-11)

Worth noting: Most varieties of clump-forming fishtail palm trees are good outdoor substitutes for invasive bamboo (the world's fastest-growing plants).
