More Details

Dahlia 'Blanc y Verde' is the most extraordinary white dahlia I've ever seen, sent to me by a Dutch friend, to trial. It looks more like a mini globe artichoke than a dahlia, with green bracts right down the stem.

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.

Genus Dahlia
Group/Species Decorative Group
Variety Blanc y Verde
Type Tender Perennial Tuber
Border Position Back, Middle
Bulb Size I
Soil Type Acid, Chalky, Fertile, Neutral
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 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 have had this dahlia for a few years now. It seems fine left in the ground over winter, but it never really makes any impact - as others have suggested, flowers late and not very profusely. There are better options.

Not the right dahlia

Reviewed 1st January 2018 by Alison Agnew

I ordered a number of these after trialling one the previous year. This year the plants ordered were some other white decorative dahlia entirely lacking green collar and green centre.

I don't expect to get the wrong plants when paying these prices. We should be able,to give a no star review!

Flowers appeared mid September ( yes I planted them late) but have more layers of petals than expected . I had expected something a much more delicate flower.

My experience is that these start flowering late , 1srweek in August but have been very productive since then and still going strong 3rd week September. I planted 3 and each one has around fifteen to twenty flowers with a similar number of buds coming up. My favourite plant at this end of the season.

I ordered this dahlia and grew the plant on in a pot first then transplanted to my allotment. It is the first of my Dahlias to flower as yet and there are lots of buds developing. Flowers are nicer than I thought and the plant is very robust

This was lovely, when it flowered, but it only flowered right at the end of the season and produced very few flowers. I liked them, they were unusual and delicate, and will try it again this year as have saved tubers, but wouldn't give it a 3rd year if it produces poorly again this year. I grew it indoors in a greenhouse as well, so it didn't have much excuse. The other dahlias were much more productive.

No flowers....

I agree entirely with the Queen of Carthage. Our three tubers of Blanc y Verde produced apparently healthy foliage but no flowers - unlike the other dahlias which have been doing well.

Halfway through August, and I'm still waiting for my Blanc y Verde to flower. All my other dahlias are huge and producing prodigious quantities of flowers (including the other tuber that I purchased new this year) but the Blanc y Verde has yet to produce anything. Maybe it will do better next year? But so far, quite a disappointment.

Reply from the Sarah Raven Team:

"Thank you for your feedback. The Dahlia 'Blanc y Verde' is an unusual variety of dahlia, with green bracts that develop throughout the stems and the flowers are a lot smaller than other dahlia varieties. We would however, have expected the plant to be in flower by now, so it might be that we need to look into this further for you. The tuber will grow again next year and might well flower better but if you would like to discuss it further with our horticultural adviser please contact plantadvice@sarahraven.com or call 0345 092 0283 and we will assist you further."
