Potato 'Blue Danube'

Solanum tuberosum, Potato 'Adam Blue'

Tender Tuber

 Customer Rating

Early maincrop.

Potato 'Blue Danube' (previously known as 'Adam Blue') is the latest introduction from Sárvári, without the Sárpo prefix. The stunning blue-purple skinned oval tubers have bright white flesh of good flavour, that are excellent for general culinary purpose - larger tubers bake particularly well. This early maincrop shows moderate foliage blight resistance and excellent tuber blight resistance. Height and spread: 60cm (24").

Plant early maincrop potatoes from March. Prior to planting, 'chit' the seed potatoes by setting them out in a cool, bright position (10C/ 50F) to allow them to sprout.

When growing early maincrop potatoes in the ground avoid planting in soil where potatoes have grown for two years in succession to reduce the risk of disease. Prepare the planting area in a sheltered position in full sun on moist well drained soil. Dig in plenty of well rotted manure. Plant potatoes in rows at a spacing of 45cm (18"). Rows should be set out 75cm (2', 6") apart. Place the seed potatoes into 10cm (4") deep trenches and backfill the soil to refill the trenches. When shoots reach 20cm (8"), mound up soil around the shoots leaving just a few cm showing. Repeat this process after a further 3 weeks.

Where space is limited, try growing potatoes in potato bags on the patio. Fill an 8 litre potato bag to just below the top of the bag with good quality compost mixed with some well rotted manure. Carefully plunge a single chitted potato tuber into the compost with the shoots pointing upwards at a depth of 12cm (5") from the soil surface. Place the bags in a sunny position and water regularly to keep the compost moist.

Weed between rows and keep potato plants well watered throughout the growing season. If the risk of frost threatens, draw some soil up around the stems to protect them, or move potato bags to a frost free position in a shed or greenhouse. Early maincrop varieties can be harvested approximately 15 weeks from planting when the foliage begins to turn yellow and die back.

  1. Great Taste

    By Matt Akers 27-08-2012

    These purple spuds arnt just a novelty. They taste better and crop heavier then any other potato iv grown. The flowers would also hold there own even in the most delicate and beautiful bucket. All round winner!

  2. Good buy!

    By Arati Kumar 28-01-2012

    grew these last year and got excellent large potatoes compared to the other supermarket variety I had put in simultaneously. it was my first year at growing potatoes but this one definitely gave me the best yield with minimum care..! Recommended.

  3. The Best Keepers!

    By Andre Hutchinson 12-01-2012

    Second year of growing these and are the best...Huge yield and they keep better than any other potato we've grown (and thats a lot!)..Still have sacks of them from last season....and its now January ..and they are perfect!

  4. Blue Danube, a lovely potato

    By Paul jewell 18-09-2011

    I had no trouble boiling them but then mine went into the ground late and were not large as a result. The flavour is wonderful and they are excellent either hot or cold.

  5. Blue Danube - mash with no lumps.

    By Pamela Riddet 15-09-2011

    Reasonable crop of medium sized tubers despite going in the ground late. Not affected by the blight that went around the allotments. No slug damage. Excellent mashers - no lumps!

  6. Blue Danube beautiful spuds but tricky to cook

    By h Doman 08-05-2011

    'Blue danube' potatoes grew brilliantly with a good crop of medium sized spuds and was resistant to blight which had effected a lot of my neighbours spuds. This purple potato looks stunning although the only way to eat them is to bake them as they almost dissolve if you try to boil or fry them.
