Dahlia 'Indian Summer' is the best spiky, brilliant-red dahlia of all varieties we've trialled and excellent as a splash of brightness amongst the crimsons.

  • are first class, healthy tubers – the largest and best you can buy.
  • come with full planting, spacing and cultivating instructions for beginner gardeners

Genus Dahlia
Group/Species Semi-cactus Group
Variety Indian Summer
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 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.

Followed the instructions on how to bring on the tuber. Planted it at the end of May. Was just going through the order I received it with to see how the plants compared. Have to say the height of this plant is all wrong! Not 3ft but at least 6ft. Obviously growing conditions suit the plant. No complaints at all.

My garden looked bright and beautiful with the Indian Summer dahlia alongside Hillcrest Royal. I had so many cut flowers too.
Thank you!!
Not very good

Two problems:
- definitely orange, not red as stated;
- flower stems too tall and bent right over. Happy to stake the plant - but not the flower stems too.

Reply from the Sarah Raven Team:

"Thank you so much for your comments. How strange that yours has flowered orange, as we've not had any other reports from customers about this. Perhaps you could email info@sarahraven.com a picture of them? To help strengthen your plants, Sarah normally recommends pinching out all but 5 stems, see her guide for more info, http://www.sarahraven.com/articles/how_to_plant_and_grow_dahlia_tubers.htm, as this may help."

Planted in a container in my sunless London patio, this performed superbly, giving enormous fiery flowers well into November. Looked good with the nearly black 'Chat Noir'. They were rich orange, however - not the red described in the catalogue. Only wish I had room to plant many more, to add joy as the cold and darkness descends.
