Producing electric orange blooms that delicately fade into white toward the flower’s tip, Dahlia ‘Colour Spectacle’ lives up to its name with its flamboyant warm hues and energetic, curled petals. Plant in amongst a variety of richly coloured dahlias for optimal effect.

Classed as ‘Cactus Dahlias’, these magnificent perennials feature masses of slender yet seemingly spiky, bright flowers, the petals of which roll inwards or outwards to more than two-thirds of their length.

  • Flowers: June - September
  • Hardy
  • Fertile, moist, well-drained soil
  • South, East or West aspect
  • Full sun or partial sunlight
  • Sheltered
  • For early flowering, tubers may be started off in individual pots under glass from March
  • Once the last of the frosts have passed in mid to late May your dahlias can be transferred into the garden. Plant the dahlia facing upwards with the tip of the tuber peering out of the soil, then water generously. For more information on how to plant your tubers, why not take a look at our guide.

Feed weekly, and water well in hot weather. The tall flower stems will require staking and tying in, but this is well worth the trouble for the magnificent display that they produce. Larger flowers can be obtained by pinching out the side buds and just keeping the terminal buds. Deadhead spent flowers to encourage more buds. Lift the tubers once the foliage has died back and store in a frost-free location in moist sand or compost. Find out more about over-wintering your dahlias with our helpful guide .
