  • Dahlia 'Soulman'
  • Dahlia 'Happy Single Romeo'
  • Dahlia 'Tamburo'

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.

This can be gift wrapped in our exclusive hessian sack, with ribbon and a Sarah Raven gift card. You will be able to add this to your basket once you begin the checkout process. To add a gift message to your order, simply fill out the details at the delivery stage of the checkout.

Genus Dahlia
Type Tender Perennial Tuber
Bulb Size I
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.

To complete the original trio I bought young plants of Dahlia Roxy as due to a crop failure the tubers were not available. The combination has been very striking and into August is still going strong

Service good but tubers quality so far poor. Only 2 out of 5 purchased have sprouted (so far- potted over 2 weeks ago).

Possibly arrived a little early. We ended up planting in pots in a spare bedroom and they are now in a cold greenhouse to get enough light.
Lets hope they do well!

A very inspiring video about these lovely dahlias. I am trying to get up my nerve to order the container collection for my patio garden but as ever I'm unsure about the actual size of pot required per tuber. I probably wouldn't underplant as I like the dahlia foliage.
