Mandevilla Diamantina ‘Agathe’ is a spectacular climbing plant prized for its large, elegant white flowers and lush dark green foliage. Its vigorous climbing habit makes it an excellent choice for adding vertical colour and tropical-style beauty to patios, courtyards, balconies, pergolas and trellises.
The large trumpet-like blooms measure approximately 10–11cm across and appear generously from spring through early autumn. The crisp white flowers provide a beautiful contrast against the rich dark green, elliptic foliage, creating an eye-catching display throughout the warmer months.
‘Agathe’ is best suited to warm climates and is not frost hardy, performing reliably in USDA Zones 9–11. It can also be grown in containers where it can be supported with a trellis or other climbing structure.
