Hylocereus costaricensis, the Costa Rica Pitahaya, is a cactus species native to Central America and northwestern South America. The species is grown commercially for its Pitaya fruit, but is also an impressive ornamental vine with huge flowers. Most plants grown under the name Hylocereus polyrhizus refer to this species. The latter name is ambiguous and not used.


Named after Costa Rica where it was first discovered
