Mandevillas Are Hot
Mandevillas (formerly Dipladenea) is a genus of climbing plants from Central and South America. In subtropical regions also known as Brazilian Jasmine.
There are 3 groupings: the large flower group which has bigger leaves are definite climbing plants and have the much bigger blooms, e.g Alice du Pont. Then there is the lesser known Mandevilla laxa which has white fragrant flowers and is deciduous in cool climates. And lastly, there is the largest grouping of Mandevillas. Formerly known as Dipladenea with medium and smaller flowers and plants that are climbers as well as loose-limbed shrubs.
Interspecific breeding by Australian breeding duo Graham Brown and Mal Morgan has created an outstanding new Mandevilla series called the Aloha range which features continuous flowering between spring and autumn.
The Mandevilla will flower virtually all year in a warm, sunny position. It really comes into its own through the heat of summer, but seems to carry blooms all year. Classified as a small climbing plant. It can also be kept as a loosely formed shrub by pinching out the tendril tips. The flowers are trumpet shape and come in a variety of colours ranging from a rich vibrant scarlet, through the reds to pinks and white. All have a distinctive yellow throat. The overall effect is one of massed exotic colour.
Flowering consistently from spring to autumn, the Aloha series produces fabulous flowers in bold colours that contrast beautifully against lush green foliage. Although these plants are climbers, they are not overly aggressive which makes them easy to control. These hardy and heat loving plants are perfect to train on a trellis, pergola or cyclone fence.
Dipladenias love the sun! They also seem to thrive best in large pots. The root system develops in a tuber-like way, storing moisture for dry times. There’s no need to panic over the watering – in fact don’t over to do it. Make sure drainage is perfect, tip prune if you wish a shrub shape or allow to mature as a climbing plant with a support. Fertilise with a slow release feed in spring, early and late summer. An occasional aplication of diluted Seasol is beneficial. Mandevillas may very rarely get scale, which is easily controll by spraying with eco-oil.
Use Dipladenias in hot spots: at an entrance way in decorative tubs, as a climber on a lattice work trellis on a balcony, in very large baskets and urns and they look great planted in groups near a pool setting. Actually because they are such a tidy plant they are excellent for pool side plantings. Without doubt, the Dipladenia family is one of the most rewarding and easy to care for group of plants available to the home gardener.
