Thespesia populnea, commonly known as Portia Tree and Milo, is a versatile and resilient tree recognized for its expansive canopy and multifaceted uses. Indigenous to the Old World tropics and possibly introduced to Hawai'i by early Polynesians, this coastal guardian stands as a testament to adaptability and beauty. Standing tall at up to 30 feet with a spread as wide, this evergreen marvel exhibits a majestic presence with its shiny green, oval or triangular leaves, each ranging from 2 to 12 inches in length. The captivating hibiscus-like flowers bloom consistently throughout the year, starting the day in a delicate light-yellow shade with a contrasting maroon center and gradually transitioning to a deep orange by day's end.
Portia Tree thrives amid coastal conditions, enduring salt spray and wind, making it an ideal solution for creating shaded shelters in seaside areas. While its rapid growth slows after seven years, flowering can begin as early as two years into its life. Despite its tendency to drop leaf litter and papery seed capsules, it remains easy to propagate through seeds or vegetative cuttings. The tree is not just an ornamental delight; it serves multiple purposes, including food, medicine, cordage, lei materials, and fine wood. Widely found throughout the tropics and considered invasive in places like Florida and Brazil, Thespesia populnea is truly a global tree enriched by its vast array of uses and enduring coastal legacy.
