Bush Allamanda (Allamanda schottii) is a compact, woody evergreen shrub native to tropical South America and widely grown across India for its showy, golden-yellow, trumpet-shaped flowers. Unlike the climbing golden trumpet, this species stays bushy and mounded, making it ideal for hedges, borders, and large pots.
It blooms generously through the warm months and, in frost-free parts of India, can flower nearly all year. The glossy whorled leaves and cheerful flowers make it a popular low-maintenance choice for sunny gardens, terraces, and balconies.
Like all Allamandas, every part of the plant contains a milky sap that is toxic if ingested and can irritate skin, so it should be sited away from young children and pets.
