More Details

The new, perhaps even more glamorous sister of 'Jescot Julie', 'Dark Butterfly' – its crimson petal backs matching the silk petals of 'Ripples'.

This collection contains:

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.

Common Name Dahlia
Border Position Cutting Garden
Bulb Size I
Soil Type Broad Tolerance
Scent Unscented
Site Full Sun
Moisture Moist but Well-drained
Height 90cm (36in)
Spacing Plant just under the soil surface, 75cm (30in) apart.
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.
Cooking Notes All dahlia flowers are edible. I use the petals scattered over salad and to decorate a range of puddings.

I had such high hopes for this collection. The catalogue photos and description and some of the customer reviews made this sound a perfect choice for cut flower arrangements. And I agree that they are very beautiful flowers that go well together. But .. Ripples produced one enormous flower in early August, then nothing until the second week of September when it produced four or five flowers, and no further buds to be seen. ( It is a very short plant - barely 30cm). Dark Butterfly has just produced its first flower (the second week of September) and there are no further buds to be seen. Unless the pair of them are planning a surprise appearance in October, I won’t be picking these two for any flower arrangements this year.

Lovely strong plants, even though they were planted late due to being bought in the sale.

Firstly my mother often buys from you and always has an amazing display. This year I joint purchased tulips with her which were fabulous and subsequently bought dahlias they are in bloom now . Everything arrived on time with no damage. I will need more slug control next year as I lost one to the little critters

Have never grown Dahlias before, thought them rather suburban if I'm honest. But I was seduced by the photographs in the catalogue. Wow!! am I glad I was. They are stunning. Can't make up my mind which is my favourite but together they are glorious. Still flowering their heads off second week in October with plenty of buds still opening. Haven't needed staking.
