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.

Uses
Bush Allamanda is a versatile ornamental across Indian gardens:
- Flowering hedge, border, or foundation planting in sunny gardens
- Container and large-pot plant for terraces, balconies, and entrances
- Mass planting for a long-lasting splash of yellow colour
- Low-maintenance landscaping for resorts, parks, and commercial frontages
Growing tips
Plant in spring once the weather warms for the strongest establishment before the monsoon.
- Give it the sunniest spot you have, at least 5-6 hours of direct sun, for maximum flowering.
- During the monsoon, ensure pots and beds drain freely to prevent root rot.
- Feed every 3-4 weeks from spring to early autumn for continuous blooms.
- In North India, shift potted plants to a sheltered, sunny spot during cold December-January nights.
- Pinch growing tips on young plants to encourage a dense, bushy shape.
