Common Name:
Mandevilla ‘Aloha Giant Red Romance’
Common name – Dipladenia
Description:
Mandevilla ‘Aloha Giant Red Romance’ is a vigorous, tropical-style climber renowned for its large, velvety red trumpet-shaped flowers and lush, glossy green foliage. The bold blooms are produced generously from late spring through summer and well into autumn in Melbourne’s warmer months, creating a striking display against walls, trellises, pergolas, or in large decorative pots. Its twining growth habit allows it to quickly establish vertical coverage, adding height, colour, and a resort-style feel to outdoor spaces. Thriving in full sun to part shade, this variety prefers well-drained soil enriched with organic matter and benefits from consistent watering during active growth. In Melbourne, it performs best in a warm, sheltered position protected from cold winds and frost. Regular feeding throughout the flowering season will encourage continuous blooms, while light pruning helps maintain a tidy shape and promotes bushier growth.
