The Purple Allamanda is a tropical showstopper, admired for its large, trumpet‑shaped flowers in vivid shades of purple to violet. Glossy, evergreen foliage provides a lush backdrop, while the blooms add a dramatic splash of colour from spring through autumn (September-April). In Cape Town’s warm Mediterranean climate, it thrives in sunny, sheltered positions, bringing a touch of the tropics to gardens, patios, and pergolas. Best planted in spring (September-November) or early summer (December), Allamanda establishes quickly in well‑drained soil. With regular watering and feeding, it produces an abundance of flowers over a long season. Though often trained as a climber, it can also be pruned into a dense shrub, making it versatile for both ornamental borders and vertical displays.

Note: All parts of the plant are toxic if ingested, so keep away from pets and children.

Why You'll Love It:

• Exotic purple trumpet flowers in abundance.
• Long flowering season from spring to autumn.
• Glossy evergreen foliage for year‑round appeal.
• Versatile growth habit: shrub or climber.
• Adds tropical flair to Cape Town gardens.

Plant & Care

Plant in full sun in fertile, well‑drained soil. Water regularly during the growing season, especially in summer (December-March), and feed with a balanced fertilizer to encourage continuous flowering. Prune lightly after flowering to maintain shape and promote new growth. Protect from frost in cooler months, as Allamanda prefers warm conditions.
