More Details
I like the rich colours planted together and then I like the pales, none more so than these two white and green flowered dahlias - perfect for the white or pastel garden.

- 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.

| Genus | Dahlia |
| Group/Species |
Cactus Group, Similar to semi-cactus, but with narrower petals. Also includes Fimbriated Cactus dahlias. Click here for more information about dahlia groups. Broad and flat petals, normally bluntly pointed, with no central disc showing. Click here for more information about dahlia groups. |
| Variety | Furka, White Onesta |
| Type | Tender Perennial Tuber |
| Common Name | Dahlia |
| Border Position | Back, Middle |
| Bulb Size | I |
| Soil Type | Acid, Chalky, Fertile, Neutral |
| Scent | Unscented |
| Site | Full Sun |
| Moisture | Moist but Well-drained |
| Height | 1.1m (3ft 7in) |
| 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. |

Reviewed 14th August 2019 by Barbara Mega blooms. Very successful. Complimented by a visitor who used to run a garden centre. |

Reviewed 11th August 2019 by Mary Only 1 came up, the other failed to grow. Perhaps i should have asked for a refund. |

Reviewed 3rd August 2019 by Nancy Very good service. Really like the white dahlias, dark red ones a mistake, much too dark for me and they die off very quickly, not like the white ones which last for ages in water. Loved the cosmos, antirrhinums just coming up to their best, , delphiniums are really beautiful. No don't think so |

Reviewed 2nd August 2019 by Valerie Some tubers did not grow. Plants haven’t flowered yet and I think I will purchase plants rather than tubers in future |

Reviewed 31st July 2019 by Virginia one of my dahlia tubers was mouldy and another partially eaten. I did get a replacement for the mouldy one thank you.Unfortunatly the weather here in Lincolnshire has either been very hot or very wet so flower heads have not been true |
