Dahlia 'Happy Halloween' is the perfect orange dahlia, exactly the colour of a pumpkin – neat, robust and floriferous. This is a new variety, only named in 2009, and is the best in this colour I've ever seen. It lasted very well as a cut flower for us this year too.

Our dahlias:

  • are first class, healthy tubers – the largest and best you can buy.
  • come with full planting, spacing and cultivating instructions for beginner gardeners
  • tubers should be potted up when they arrive and be kept in a light, frost-free place until the frosts are over and then be planted into the garden.

Genus Dahlia
Group/Species Decorative Group

Broad and flat petals, normally bluntly pointed, with no central disc showing. Click here for more information about dahlia groups.

Sowing, Seeds, Planting Pot them up undercover March or early April in a generous pot (at least 2 litre) filled with multi-purpose potting compost. Place them in a light, frost-free place and keep the compost moist. Pinch out their growing tips when they have reached about 8" tall. They will have formed bushy plants by the time the frosts have ended and will be in flower by the beginning of July. If you don’t have anywhere to grow the potted tubers, you can put them straight into the ground when the frosts are nearly over, mulching them or protecting with a cloche or protective horticultural fleece if the foliage appears before the frosts are over, but this will delay flowering.
Care Tips Support with a stout stick, tie in every couple of weeks. In the south you can mulch deeply and overwinter them in the ground, alternatively, lift and overwinter your dahlias frost free undercover.
Flowering July - November
Vase Life Only pick dahlias in full flower. Recut the hollow stem ends under water to avoid airlocks.
Cooking Notes All dahlia flowers are edible. I use the petals scattered over salad and to decorate a range of puddings.

I bought this some years ago, left it in the ground and it became a substantial plant. I left it behind when I moved house and have just bought it again because I missed it so much last year. To me, it's the best orange dahlia.

I grew this for the first time last year and was very pleased.A lovely clear orange which kept its colour well as the flowers faded and looked splendid with verbena rigida, salvia caradonna and geum 'Totally Tangerine'. Another plus is its compact size, ideal in my small town garden.
