In praise of the colour orange

Using a colour wheel when designing your garden or individual borders can be very useful when planning which plants to use. A secondary colour made by mixing red and yellow, orange is a strong, exciting, 'in your face' hot colour which seems to visually advance. Opposite colours like blue and purple seem farther away than they are, but when these complimentary colours are used together they can make the orange seem bolder. Remember too that whatever colours you use in a border, foliage will always dominate. Orange flowers lend themselves to bronze foliage, the dark of the leaves can make the orange brighter. Using colours that are adjacent on the colour wheel gives a harmonious effect, opposite colours provide contrast.
Using the colour wheel is interesting but if you find yourself at a loss when designing your borders, then go with your instinct! I don't think there's such a thing as 'clashing' colours in the garden. The wonderful gardener Christopher Lloyd in his garden at Great Dixter happily placed bright pink with sulphur yellow if he liked the result. One of my favourite effects uses orange with shocking pink! Purples, lavenders and blues are lovely complimentary colours for orange and peach.
But I admit, not everyone wants a garden or border totally dominated by orange, for some people it's just too much. But don't be put off using it. Try it in a seasonal container. A lovely autumn effect can be achieved with annuals like chrysanthemums, pansies, dahlias, coleus and grasses. Or for spring use pansies, wallflowers, 'Gypsy Queen' hyacinths, tulips and primulas.
So which plants can you use to provide some orange zest in your garden?
A subtle way of using orange in your garden is by planting shrubs that have leaves which turn orange in autumn, or that have orange coloured berries or stems. For these effects you can try Euonymus, Acers, Pyracantha, Cornus, Rhus and Cotinus.
There are azaleas which have brilliantly orange flowers. Other shrubs to provide orange flowers include Abutilon, Scotch broom and Hamamelis. Also consider the orange-flowered honeysuckles like 'Dropmore Scarlet'.
There are lots of annuals and perennials with orange flowers, including Daylilies, Crocosmia, some of the newer Echinaceas, Kniphofia, Gaillardia, Achillea 'Terracotta', Asclepias (milkweed), Clivia, Hibiscus, Leonotis, Ligularia, Lantana, Oenothera 'Sunset Boulevard', Eschscholzia (Californian poppy), nasturtiums, Belamcanda (Leopard lily). Tagetes, and Gazania.
If you have a favourite plant, find out if it's available in an orange cultivar. Add some spice to your border and prepare for a feast for the eyes!
