- 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.

| Variety | Karma Choc |
| 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 | 80cm (31in) |
| 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. |

Buy this!
Reviewed 13th October 2018 by Helen Another one I bought in the sale when I really shouldn't have been spending more money on dahlias! Beautiful on the plant, beautiful in the vase, still producing a lot of flowers now in mid October when the others are winding down. The stems are a different colour to most dahlias, so it's an interesting addition to the garden. I'm hoping this comes back just as good next year when I may well buy another. Thoroughly recommend! |
Good for the North
Reviewed 9th December 2017 by Kay Harris I was inspired to try Dahlias some years ago by Sarah's wonderful way with colour, I used to think they were a bit fuddy duddy and difficult. I am a novice gardener working in the high Pennines so our season is not just cooler than just about everywhere else but short too; I couldn't imagine such colours and profusion would grow here. Karma Choc was among the first I tried. I still have that same first tuber years later (Sorry Sarah I really must attempt to divide it!) and every year I plant it out and without further ado it produces bunches and bunches of flowers. The dramatic dark red goes with lots of other colours and makes sure my bunches never look fuddy duddy. Fantastic with Jescott Julie and Mambo both very tough, reliable and trouble free. Each year I try a couple of new varieties but whatever I grow I always grow these three, and at the end of the growing season when the rest of the garden is spent and looking a bit sad, the dahlia bed is always resplendent with profusion and colour, I have bunches of flowers in the house in glowing colours and enough to give bunches away too. Thank you Sarah. |
Good strong grower!
Reviewed 26th January 2017 by Helena Newsom I'm a novice with dahlias and have no greenhouse or fancy equipment. In 2016 this one started to sprout, grew, and flowered better than my other 3 SR dahlias varieties (eg Blue Bayou, which was really feeble). I'll be giving away bits of Karma Choc to friends, there's so much tuber now. Don't think you can go wrong with this one. Sarah Raven, please can we have ease/strength of growth ratings for your dahlias? Would really help. |
