Thespesia grandiflora, most commonly known as maga and maga colorada, and also erroneously referred to as amapola, is a tree in the Malvaceae family of the rosids clade endemic to Puerto Rico, where its flower is officially recognized as the national flower of Puerto Rico. Originally native to the humid, lower limestone mountains of the Cordillera Central and the Northern Karst Belt in the western and north-central regions of the main island, it grows everywhere in the archipelago due to its extensive cultivation. The maga is mostly used as an ornamental plant, but like the related portia, its wood is also valued for its durable timber. It is grown as an ornamental tree in Florida, Hawaii, Honduras, and various Caribbean islands.
