Bring a little of the heat of the tropics to your home with vividly coloured flowers of mandevilla (syn. Dipladenia). These are climbing perennials, normally at home in the tropical woodlands of Central and South America. Accordingly, mandevilla need the warmth of a heated greenhouse or cool conservatory to thrive in Britain’s less-than-exotic climate.
Mandevilla Sundaville Cream Pink = 'Sunparapibra'
To keep mandevilla healthy, here are a few tips on cultivation;
Mandevilla can make large plants so pruning largely helps keep them in check;
Sow seed in temperatures of 18-23°C (64-73°F) in spring.
Softwood cuttings in early summer should be successful if placed in a propagator with bottom heat of 20-25°C (68-77°F).
Mandevilla × amoena ‘Alice du Pont’ AGM (Syn: Mandevilla × amabilis): is a popular conservatory climber with large numbers of pink flowers in late summer. It reaches a height of up to 7m (22ft) and can tolerate temperatures of 10-15°C (50-59°F).
M. laxa AGM (M. suaveolens, M. tweediana; Chilean jasmine): The selling point of this mandevilla is its strongly scented flowers of white or creamy-white. It can reach a height of 3-5m (10-15ft). It can survive short periods of temperatures down to 5°C (41°F).
M. boliviensis AGM: At 3-4m (10-13ft), this is the least vigorous of those mentioned here and has white flowers with yellow eyes. Another one for the heated conservatory with minimum temperatures of 10-15°C (50-59°F).
