Thespesia grandiflora, most commonly known as Maga, and also referred to as Maga Colorada ("Red Maga") and Puerto Rican hibiscus, is a tree in the family Malvaceae of the rosids clade endemic to Puerto Rico, where its flower is officially recognized as the national flower of the archipelago. Although originally native to the humid mountains of limestone in the western and north-central portions of Puerto Rico, today it grows everywhere in the archipelago due to its extensive cultivation. It is also grown as an ornamental tree in Florida, Hawaii, Honduras and various Caribbean islands. The maga is mostly used as an ornamental plant, but like the related Thespesia populnea its wood is also valued for its durable timber.

Flower

The flower of the tree, known as Flor de Maga, is the official national flower of Puerto Rico. Though this species is contained within the same family as Hibiscus and may sometimes be referred to as such in English, truly it belongs to a different genus and species from true hibiscus, and is more closely related to Cotton.

Growth

The maga tree usually grows no larger than 20 meters. It is grown for timber and as an ornamental plant.
