-Golden Trumpet (Allamanda cathartica)
Allamanda forms a sprawling shrub or woody climber that tends to sprawl and twine itself around a support. They have brightly coloured, golden yellow flowers that contrast with the shiny dark green leaves. The flowers can span 5 inches (12 cm). Allamandas have become naturalized throughout the tropics, growing in roadside ditches, abandoned yards, and dumps.
Description
• Allamanda cathartica, commonly known as golden trumpet or common allamanda, is an evergreen climbing shrub in the dogbane family (Apocynaceae). It has glossy, dark green leaves arranged in whorls and large, bright yellow, trumpet-shaped flowers with five spreading lobes. The flowers may appear throughout the year in warm climates. Its stems contain a milky latex that can irritate the skin, and the plant is toxic if ingested.
Range
• Allamanda cathartica is native to tropical South America, particularly Brazil, and is widely cultivated and naturalized in tropical regions worldwide. It is cultivated in Zihuatanejo, Guerrero, and the surrounding area.
Habitat
• This tropical plant thrives in warm, frost-free environments with plenty of sunlight. It is commonly grown in gardens, parks, and along fences, where its long stems can climb or sprawl over supports. It prefers moist, well-drained soil and can also persist in disturbed areas and along forest edges.
