EVERGREEN TROPICAL CLIMBER · RARE YELLOW FLOWERS

Dipladenia® opale ‘citrine’

The variety that said “enough with the reds” 😌

Family: Apocynaceae · Pot diameter: 15cm · Height: 45cm

Lemon-yellow trumpets
Long warm-season flowering
Glossy evergreen foliage
Compact base with twining shoots

Dipladenia® opale ‘citrine’ is the sunlit surprise that makes a summer composition feel immediately more distinctive. Clear lemon-yellow trumpets rise above glossy deep-green leaves, creating a contrast that stays fresh even through the hottest days. The flowering display has tropical generosity, yet its colour remains refined. It draws the eye confidently without needing visual excess.

Its controlled bushy base fills readily with flowers, while longer shoots can be guided around an elegant hoop. It therefore works both as a luminous mass and as a vertical detail.

What makes it special

Three qualities explain why ‘Citrine’ changed the palette of modern Mandevilla.

Yellow with a clear glow

The corolla opens lemon-yellow without the warm red undertone of classic cultivars, so the colour reads as bright and fresh.

A compact flowering base

Shorter branches fill the centre with buds while longer shoots can wind around a slim support.

Foliage that frames the flowers

Thick glossy green leaves form a calm dark background that makes every yellow trumpet clearly visible.

Why you will love it: It brings rare yellow colour to a group dominated by red and pink, with a clean tropical presence.

In the garden & on the balconyPlacement & plant combinationsA warm sheltered setting, a clean hoop and three companions that sharpen the yellow.

Planting position

Ideal position

Place it in a sunny, warm and sheltered position with a low hoop or slim trellis that displays the flowering shoots without hiding the base.

Colour & compatibility

Compatible combinations

Work with blue, white and silver in separate pots. This keeps the bright tropical palette clear and lets each companion retain its own watering regime.

Salvia farinacea ‘Victoria Blue’ — upright blue flower spikes sharpen the lemon-yellow display without weighing it down, in a separate sunny pot
Euphorbia hypericifolia ‘Diamond Frost’ — an airy cloud of small white bracts softens the large trumpets and fills the lower layer discreetly
Helichrysum petiolare ‘Silver’ — silver foliage trails below and cools the glossy green, with a more restrained watering regime in its own pot

Care at a glance

Light

A very bright position with sun after gradual spring acclimatisation.

Watering

Water thoroughly once the top 2–3cm dries; never leave the pot standing in water.

Climate & hardiness

Tropical and cold-sensitive; protect it before nights fall towards 10°C.

Safety

Not edible; milky sap may irritate skin and ingestion may cause stomach upset.

Detailed careComplete care guideLight, moisture, drainage, feeding, support, cleaning and safe overwintering.

Gradual sun

In spring, increase direct sun over 7–10 days. Sudden exposure after protected cultivation can bleach or mark the foliage.

Moisture check

Feel the top 2–3cm of mix. Water only when this zone has dried and continue until water exits every drainage hole.

An aerated mix

Use a rich but freely drained mix and keep every hole open. Prolonged saturation deprives the fleshy roots of oxygen.

Feeding for flowers

During active growth, apply a complete flowering-plant fertiliser at the label rate and only to a moist rootball. Stop when growth slows.

Gentle training

Wind only flexible tips around a slim support and use loose ties. Older shoots can snap if forced into a sharp bend.

Cleaning & pruning

Remove spent flowers and weak shoots. If shape control is needed, shorten lightly in spring before strong fresh growth begins.

Overwintering

Before cold weather, inspect the leaf undersides for pests and move the plant into a very bright frost-free place. Reduce water and stop feeding.

Development over timeFrom compact base to flowering hoopTwining longer shoots, a dense base and summer flower distribution.

Early shaping

The compact base remains low while two or three longer shoots are guided loosely around the hoop.

Flowering fill

Side branches appear along the trained shoots and gradually fill the interior with foliage and buds.

Mature warm-season display

The hoop remains visible as a clean axis while numerous yellow trumpets are distributed from base to top.

Mature form & size

With controlled support

Height 1–2m with supportSpread 0.5–1mCompact twining

The branching base carries dense foliage and yellow trumpet flowers. Longer shoots can be arranged on a hoop; dimensions refer to this trained form.

Form through time

Controlled cultivation

Warm-season flowersWinter protection

Flowering in suitable conditionsThe branching base carries dense foliage and yellow trumpet flowers. Longer shoots can be arranged on a hoop; dimensions refer to this trained form.

Protected winter habitFoliage remains under suitable conditions. Slower growth and reduced flowering change the display without removing the basic architecture.

The studies show habit and seasonal development; growth varies with age, climate and cultivation.

What to expect after establishment: Successful establishment shows in fresh glossy leaves and buds on well-lit shoots. Complete hoop coverage develops gradually.

History & originCultivar originA French cross made in 2008 led to the yellow-flowered selection ‘Lancalifornia’, known as Opale Citrine.

Dipladenia® opale ‘citrine’ corresponds to the recorded selection Mandevilla ‘Lancalifornia’. Its journey began on 21 October 2008 in Malause, France, where Robert Lannes crossed the dark-pink Mandevilla sanderi ‘Rosea Foncé’ with an unnamed selection.

A flowering seedling was selected in May 2010. Propagation by cuttings began that July and retained its characteristics. With full branching and yellow flowers, ‘Lancalifornia’ became associated with the selling name Diamantina Opale Citrine. Plant patent USPP24074 records that development.

Greenleaf for Plant NerdsScience nobody asked forBotanical mechanisms behind form, attachment and flowering

Anthers forming a protective cone

In Mandevilla, five anthers converge around the style head and form a complex pollen-presenting unit. A visitor must pass through a narrow functional route, making contact with the reproductive organs in a controlled way. This architecture is characteristic of pollination in Apocynaceae.

Twining without tendrils

Longer shoots have neither tendrils nor adhesive roots. Climbing results from circular movement of the growing tip, which encounters a support and continues rotating around it. The support therefore guides shoot geometry without becoming biologically fused to the plant.

Frequently asked questions

Six specific answers on yellow colour, sun, water, support, winter and milky sap.

01Does it retain its lemon-yellow colour?

Yes, when it receives abundant light and balanced feeding. Severe heat stress may fade older flowers temporarily, while fresh blooms open clear again.

02Does it always need support?

The base remains compact, but longer shoots perform best around a hoop or slim trellis. Without support they can create a looser trailing line.

03How much sun can it take?

After gradual acclimatisation it enjoys several hours of sun. In an exceptionally hot midday microclimate, some shelter through the fiercest hours keeps the foliage clean.

04When should it be watered?

Water once the top 2–3cm has dried and let all surplus escape. Permanently wet, airless conditions around the roots are more dangerous than brief surface drying.

05Can it stay outdoors in winter?

It must not be exposed to frost. Move it into a very bright frost-free place before nights approach 10°C and reduce water substantially.

06What should I consider when pruning?

Wear gloves and keep milky sap away from skin and eyes. Use a clean tool and wash it after the work.
