More Details

Tartan is my plea for the vulgar - it brings jollity and naughtiness amongst the oh-so-tasteful coffees and greys.

Remember, with cut flowers, they are there to decorate your table for a few splendid days, not years. I'm not asking you to paint your house in these stripes but with some cut flowers, it's good to go for it!

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.

Please note: only items which are showing ‘in stock’ can be gift wrapped.

Sowing, Seeds, Planting Plant just under the soil surface after the last frosts. Alternativley 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.
Harvesting Flower production 5 months
Cooking Notes All dahlia flowers are edible. I use the petals scattered over salad and to decorate a range of puddings

A stunning dahlia. It has to be my favourite dahlia at the moment. It has a large flower head and the colours are so striking.

The first tuber I received was totally shrivelled- not the ‘first class, healthy tubers’ promised. It was quickly replaced by Sarah Raven’s excellent customer service and has grown strongly with good sized blooms. It’s okay - strong form and colour- but won’t be on my favourites list.
