Dipladenia x sanderi Diamantina Quartz Pink & Yellow - Rocktrumpet

Dipladenia or Mandevilla Diamantina Quartz Pink & Yellow is the leader of a new generation of exceptional dipladenias known for their robustness and unique colours. This variety bears striking flowers, combining intense fuchsia-pink with bright golden yellow. It is a small climbing plant that continuously blooms. It withstands harsh climatic conditions, sunny exposures, and drought. It adapts to all desires. It works well trained on a support in a large pot, or growing freely in a planter. It can also be grown in the ground. The Diamantina series dipladenias are generous but sensitive plants that will easily survive the harsh season behind a bay window, in a bright veranda, or a lightly heated greenhouse, and will accompany you for many years.

Mandevilla, named in honour of diplomat and gardener Henry Mandeville, are fast-growing climbing plants, mostly native to the tropical forests of Serra de Orgaos, near Rio de Janeiro, Brazil. Growing at high altitudes, these plants thrive in temperate climates, free from frost, in partial shade or filtered light in summer. They belong to the Apocynaceae family, just like periwinkles and oleanders. In the 1970s, Robert Lannes, a French horticulturist based in Tarn et Garonne, was the first to be interested in hybridising these plants with immense potential, among which Mandevilla sanderi stands out. Years of research and selection have resulted in particularly floriferous, more compact varieties with various colours. They are easy to grow by amateur gardeners.

The Diamantina series, derived from Mandevilla sanderi (among others), produces small plants that are ideal for pot cultivation. They stand out with their wide range of colours, which includes somewhat unique shades.

Diamantina Quartz Pink & Yellow has a bushy habit, but it can be trained as a climbing plant. Its voluble, woody stems easily wrap around the support provided. It will reach an average height of 85cm (34in) with a spread of 45cm (18in), with a rapid growth rate. Its rounded flowers, 6cm (2in) in diameter, are composed of 5 large lobes that overlap like the blades of a propeller. Grouped in small clusters, they bloom continuously from May to the first frost. The evergreen and leathery foliage consists of small, entire, dark green leaves arranged in an opposite manner. The thick and leathery lamina, oval to elliptical in shape, measures 5 to 6cm (2in) long and has a shiny upper surface. This plant possesses fine roots and also large tuberous roots that contain starch and water, helping the plant to withstand drought quite well.

Mandevilla is often used for decorating pergolas and trellises on patios and balconies, alone or in a mix of colours. This heat-resistant and water-efficient variety is best suited for a large decorative pot placed in isolation. It will also look beautiful in a hanging basket or a container, placed on a sunny patio or balcony. It will look wonderful with the Jade Rose variety, the dark-blue flowers of Plumbago capensis, black-eyed Susans, and passionflowers. It can be planted directly in the ground in well-drained soil. However, this is only possible in mild regions without frost.
