Buy Dahlia 'Downham Royal' ball dahlia tuber: Sumptuous pompoms for cutting or the border

  • Position: full sun
  • Soil: fertile, humus-rich soil
  • Rate of growth: average
  • Flowering period: July to September
  • Hardiness: half hardy (may need winter protection)

    For several months from midsummer, the upright stems of this striking dahlia are topped with miniature ball-shaped, magenta flowers, which are wonderful for adding a strong contrast to softer pinks and purples.

  • 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 over-crowded. 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.

Fabulous colour!


In its first year smaller flowers than I expected but fantastic colour! Big, strong ,healthy plants did not need staking. Tubers grew quite large and take up a lot of space in my small greenhouse over winter!




Very good quality.


Very pleased with quality of plants ordered.

Small Ball, not quite


Tubers planted and grew well, lots of flowers all season, didn't quite achieve a ball shape. Very nice though. Tubers are now lifted for next year.

Beautiful but slug-prone


This dahlia is very attractive and fits in well with my summer garden colour scheme but is very slug-prone and needs appropriate protection.

Bright and beautiful


Had this in a pot for its first year, dug into the soil. It performed well after a late start. It is a lovely, vibrant colour



Plenty of whiz and bang!


A real stunner for its multiple blooms. It lasted well into autumn with a lovely display of small pom pom blooms. Deep colour that didn't fade until the 1st frosts.
