Orange flowers are brilliant at bringing warmth and intensity to the garden.
They comes in different shades, too, from more yellow tones of Berberis darwinii, to the reddish orange blooms of Mexican sunflowers.
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.
Of course, this is far from all the plants with orange flowers you could grow – find plenty more on our Plant Finder.
