context_page_description: Hylocereus costaricensis, the Costa Rican pitahaya or Costa Rica nightblooming cactus, is a cactus species native to Costa Rica and Nicaragua. The species is grown commercially for its pitahaya 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.
