More Details

Dahlia 'Roxy' is an incredible magenta colour with beautiful crimson leaves. This is one of the very best dahlias for pots, flowering without cease for four months at a stretch.

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 Single-flowered Group
Variety Roxy
Type Tender Perennial Tuber
Border Position Middle
Bulb Size 1
Soil Type Acid, Chalky, Fertile, Neutral
Scent Unscented
Site Full Sun
Moisture Moist but Well-drained
Height 70cm (28in)
Spacing Plant just under the soil surface, 75cm (30in) apart.
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.

They were slow to get started even though I followed instructions to the letter, but are now flowering well and are very pretty.

They started off very well in pots, but I do not think they liked the very hot weather. Maybe I allowed them to dry out.

A really good doer

I agree with the comments made in the earlier review. Roxy starts early and just keeps on going. There is never a time when there are no flowers open. I grow mine in front of a group of raspberry and white lilies and it is a wonderful combination

Dahlia 'Roxy' just keeps flowering!

Reviewed 28th January 2017 by Bonar

Last year I bought 3 rooted cuttings of Dahlia 'Roxy' and grew them on before planting them outside in late May. From mid July onwards they just kept flowering until the first frosts. They have intense magenta flowers and the bees seemed to love them too. I grew them in big glazed pots where they seem to flourish and I fed them well. So now I'm looking forward to starting them off again this March... (along with all the others I've started to collect) ;) Recommended!
