More Details

I came across Dahlia 'Blue Bayou' in the wonderful De Boschhoeve Dutch garden three years ago and have only just recently managed to find enough tubers to sell. New and very exciting.

Our dahlias:

  • 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 Anemone Group
Variety Blue Bayou
Type Tender Perennial Tuber
Border Position Back, Middle
Bulb Size 1
Soil Type Acid, Chalky, Fertile, Neutral
Scent Unscented
Site Full Sun
Moisture Moist but Well-drained
Height 100cm (39in)
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.

So pleased i have found this dahlia; it is stunning and became a large plant in its first year. I now wish that I had used a bigger pot because I think the size of pot I normally use for dahlias is too small but I am reluctant to re-pot in case I damage the growth. I have not noticed many pollinating insects on it but that could be about the position. Highly recommended.

I've grown this dahlia for 3 seasons now in our little garden and it has to be the one that people stop to look at from the path that goes by our front garden the most. When the sun shine's its large, soft lilac petals look radiant and its centre sparkles attracting the buzz of bees despites it doubled centred appearance. In the evening it takes on a more sultry, mysterious -Alice and wonderland appearance, I'll never go a summer without setting this one - unique and magical!
