Orange flowers are brilliant at bringing warmth and intensity to the garden.
Orange flowers aren’t exactly demure, so don’t be afraid to combine them with other intensely coloured blooms to provide daring combinations. Great Dixter’s Christopher Lloyd did just this, pairing up luminous oranges with purples, pinks, reds and yellows to dazzling effect.
Exotic borders are particularly accommodating to orange flowers, where the warm colours can echo the balmy origins of the plants.
Discover some of the best orange flowers to grow, below.
Nasturtiums (tropaeolum) are vigorous, hardy annuals. In the case of Tropaeolum majus, all parts of the plant are edible and it can be grown as a companion plant alongside brassicas, helping to draw away small and large white butterflies.
Blazing hot Mexican sunflowers (Tithonia rotunidfolia) are free-flowering annuals, ideal for spicing up beds and borders. They’re also brilliant plants for polllinators and last well as cut flowers. Try combining with salvias, agastaches and aromatic nicotianas.
The California poppy, Eschscholzia californica, is a hardy annual that’s perfect for sowing in pots and containers, or in gaps in borders. Check out our advice on how to sow California poppies outdoors. For darker orange flowers, try a cultivar like ‘Mikado’.
There are geums to grow in just about every shade of orange, from peachy ‘Pineapple Crush’, to luminous ‘Totally Tangerine’, to burnt orange ‘Firefinch’. Try growing them in a mixed herbaceous border alongside verbascums and scabious.
In this case, you have the option of growing oriental lilies (lilium) or daylilies (Hemerocallis) – or both if you like! If you have clay soil, daylilies are ideal, whereas oriental lilies do better in a well-drained, acidic soil.
Aptly named red hot pokers for their hotly coloured blooms, kniphofias are easy-to-grow hardy perennials. Try growing alongside other plants that also enjoy moist, well-drained soil in full sun, such as achilleas and Euphorbia mellifera.
These magnificent perennials are native to western and central Asia. Reaching an impressive 1.5m in height, foxtail lilies are at home in a sunny spot, in well-drained soil – a gravel garden or similar is ideal. Many varieties have orange blooms, but yellow- and white-flowered varieties are easy to find, too.
Trumpet vines (campsis) are fast-growing climbers are perfect for quickly covering sunny walls and fences. Despite exotic appearances, they’re hardy to -10°C. For rich orange blooms, take a look at cultivars like ‘Indian Summer’ and ‘Madame Galen’.
Berberis darwinii is a robust, evergreen shrub, producing masses of luminescent orange blooms in April and May. It works well as a compact hedge, too. Other barberries with orange flowers include Berberis x lologensis and Berberis linearifolia.
Witch hazels (hamamelis) are deciduous, winter-blooming trees with distinctive, fragrant blooms. There are lots of cultivars with orange flowers, as well as others with red and yellow flowers. Check out ‘Aphrodite’, ‘Jelena’ and ‘Orange Beauty’.
