  • Position: full sun
  • Soil: fertile, humus-rich soil
  • Rate of growth: average
  • Flowering period: July to October
  • Hardiness: half hardy

    A sumptuous cactus dahlia with garnet red flowers (up to 15cm across), which have a near-black centre. The fully double flowers have long and narrow, pointed petals that recurve for more than half their length. This dahlia looks great planted in bold groups in a sunny, sheltered border or as part of an exotic scheme. The flowers appear from July until the first frosts, and make excellent cut flowers.

  • Garden care: Dahlia tubers can be planted outside after frost, or started off in pots under glass in late winter to early spring. Plant them horizontally approximately 12cm deep, making sure the ‘eyes’ are uppermost. Allow enough room between each tuber so the plants can grow and spread to their full size without being overcrowded. While in growth, provide a high-nitrogen liquid feed each week in June, then a high-potash fertiliser each week from July to September. Stake with canes or brushwood if it becomes necessary. In mild areas, leave them in situ over winter, but protect the crown with a generous layer of dry mulch. In colder areas, carefully lift and clean the tubers once the first frosts have blackened the foliage and allow them to dry naturally indoors. Then place the dry tubers in a shallow tray, just covered with slightly moist potting compost, sand or vermiculite and store in a frost-free place until planting out again.

Worth the wait!


I bought a batch of these as a Christmas present and felt a bit odd about giving just a card with the promise of their later delivery. However, I have just seen them in full bloom and they are absolutely magnificent. The flowers are so big and vibrant, they make a striking display. Would highly recommend for anybody stuck for pressie ideas!

Garden Club Show winner


We planted this dahlia around the garden as we were not sure how our diverse soil conditions would affect its growth. It did well in all locations and we chose it for our Dahlia entry at our local garden club show. We were delighted to receive a lovely red FIRST award card and a number of visitors asked us for the name of the dahlia which we were happy to share.

Very disappointing year for all my dahlias


Planted several varieties of dahlia but only two flowered and not very well. I was looking forward to some rich autumn colour but not to be. Only mitigation was that Monty Don said his had not been very good and put this down to the very dry, hot summer and had not watered them enough.




I would buy this again


Produced a good display of large flowers through till 1st frost.

Stunning and prolific


Beautiful dark crimson velvety blooms. Flowered until the first frosts. I was cutting blooms every day! Needs good support and space.




Beautiful colour


Beautiful strong plants and excellent cut flower with a sumptuous colour.




Dahlia Chat Noir


Very Beautiful. Always a little concerning. Doesn't always overwinter well. Even in London it might be safest to lift.
