Magnolia portoricensis is a fairly large evergreen tree that can grow as tall as 25 m. In Puerto Rico it can be found specifically in state forests of the central region such as Carite, Toro Negro, Guilarte West and Maricao, and in higher elevation areas like Ciales, Jayuya and Adjuntas.. This tree grows in cloud forests with about 2000 to 4000 mm of rainfall per year. It is found mostly on the peaks and slopes of mountains, thriving best in volcanic areas. These soils are derived from igneous rocks (including serpentine), have high clay content, and are moderately well drained, with pH between 5 to 7.5. Abundant moisture in the soil is typical and may be essential for the development of the jaguilla.
