More Details

Dahlia 'Bishop of Canterbury' has the most luscious combination of dark foliage and rich plum-magenta flowers. This is a beacon outside my office. It flowers prolifically for months.

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 Miscellaneous Group

Orchid-flowered and Peony-flowered types are classified as Miscellaneous. Also includes Double Orchis-flowered, Bishop, Mini Bishop and Star dahlias. Click here for more information about dahlia groups.

Variety Bishop of Canterbury
Type Tender Perennial Tuber
Common Name Dahlia
Border Position Middle
Bulb Size I
Soil Type Acid, Chalky, Fertile, Neutral
Scent Unscented
Site Full Sun
Moisture Moist but Well-drained
Height 1m (3ft 3in)
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.

Excellent service and your staff are absolutely lovely. I am a great Sarah Raven fan. The Bishop of Canterbury dahlias also did not represent the colours inthe catalogue.

I have had 3 disappointments from SR this year:

A green dahlia which turns out to be agapanthus seedheads

Climbing Borloti beans which weren’t climbers.

Cookery course which was cancelled

My enthusiasm is somewhat dampened.

This is the only tuber that has produced a reasonable number of flowers. However,it is not particularly vigorous. All the 'cheap' dahlia tubers I bought have grown very well and are producing a good display of flowers. I would definitely not buy dahlia tubers from Sarah Raven again. I will be interested to see if anyone responds to my reviews.

These flowered beautifully all summer. They did not grow very tall so did not need staking. Lots of lovely blooms for cutting. Only drawback was that after a very wet spell in September, the leaves became quite marked.
