Pink trumpet tree is primarily native to islands in the Caribbean, where it is both widespread and cultivated for its ornamental value. Its presence extends beyond its native range into other regions, most notably the Pacific Islands and parts of Africa, where pink trumpet tree can be found mingling with local flora. While pink trumpet tree has been introduced to various continents, its cultivation is generally managed, although in certain areas pink trumpet tree may have an impact on native ecosystems. In its introduced range, especially in the Pacific, pink trumpet tree may be sometimes thought to be gently competing with indigenous species.

Pink trumpet tree contains alkaloids that pose mild toxicity to humans, cats, and dogs through contact or ingestion. Symptoms in humans include skin irritation, nausea, vomiting, and diarrhea. Cats and dogs may also exhibit gastrointestinal upset. Immediate veterinary care is essential if pets are poisoned. Handle pink trumpet tree with care, particularly around children and pets.
