Safety Overview
1.Plumeria Obtusa — Essential Profile
Plumeria obtusa, commonly recognized as the Singapore graveyard flower or White Frangipani, is a captivating species within the dogbane family, Apocynaceae. This evergreen shrub or small tree is indigenous to the sun-drenched regions of the Caribbean, Mexico, and Central America, thriving in tropical and subtropical climates where it has become widely naturalized due to its aesthetic appeal and intoxicatingly fragrant blossoms. Typically reaching heights of 2 to 8 meters (6-26 feet), it develops a characteristic spreading habit, often featuring multiple trunks. Its foliage consists of alternate, simple, obovate to oblong leaves, measuring 10-30 cm in length and 5-10 cm in width.
The upper surface presents a glossy, deep green, contrasting with a paler, subtly hairy underside. The specific epithet 'obtusa' aptly describes its rounded or blunt leaf apex. Flowers are borne in terminal corymbs, showcasing a highly ornamental display of typically white petals with a vibrant yellow center, though variations exist. Each flower comprises five broad, overlapping petals forming a distinctive pinwheel shape.
The sweet, intense fragrance, particularly strong in the evening, enhances its allure. Following successful pollination, it produces slender, elongated follicles, usually 10-20 cm long, which encapsulate numerous small, winged seeds. Beyond its ornamental value in landscaping, hedging, and as a specimen plant, Plumeria obtusa holds significant cultural importance in many regions, frequently associated with sacred spaces like temples and cemeteries, symbolizing immortality and new beginnings.
