The purple shell and the blue grain inside make for a real eye-catcher on every table. In terms of taste, the blue potato can keep up with its yellow relatives without any problems, which was probably one of the reasons why it was voted Potato of the Year in 2006.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Blue_Swede_potato_characteristics_and_origin\"><\/span> &#39;Blue Swede&#39; potato: characteristics and origin<span class=\"ez-toc-section-end\"><\/span><\/h2><div id=\"ez-toc-container\" class=\"ez-toc-v2_0_65 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<p class=\"ez-toc-title\">Table of Contents<\/p>\n<label for=\"ez-toc-cssicon-toggle-item-6616a87a9a9f3\" class=\"ez-toc-cssicon-toggle-label\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/label><input type=\"checkbox\"  id=\"ez-toc-cssicon-toggle-item-6616a87a9a9f3\"  aria-label=\"Toggle\" \/><nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/gardender.com\/blue-swede-potato-growing-harvesting-the-blue-potato-variety\/#Blue_Swede_potato_characteristics_and_origin\" title=\" &#039;Blue Swede&#039; potato: characteristics and origin\"> &#39;Blue Swede&#39; potato: characteristics and origin<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/gardender.com\/blue-swede-potato-growing-harvesting-the-blue-potato-variety\/#Growing_blue_swede_potatoes\" title=\" Growing blue swede potatoes\"> Growing blue swede potatoes<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/gardender.com\/blue-swede-potato-growing-harvesting-the-blue-potato-variety\/#maintenance\" title=\" maintenance\"> maintenance<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/gardender.com\/blue-swede-potato-growing-harvesting-the-blue-potato-variety\/#Harvest_and_use_of_blue_Swedish_potatoes\" title=\" Harvest and use of blue Swedish potatoes\"> Harvest and use of blue Swedish potatoes<\/a><\/li><\/ul><\/nav><\/div>\n\n<p> The &#39;Blauer Schwede&#39; potato, also known as &#39;Blue Congo&#39; or &#39;Idaho Blue&#39;, is an old variety, the origin of which experts do not agree on. The origin of the blue potato is believed to be in South America. The strong blue color depends on the content of the so-called anthocyanins. These are natural coloring agents that can also be found in other red or blue fruits and vegetables. They are also said to have a positive effect on human health, as they ward off harmful metabolic products. <\/p>\n<p><img decoding=\"async\" class=\"aligncenter\" src=\" \/wp-content\/uploads\/8671f77b11ea3bad120485217a7c6868.jpg\" alt=\"\u2018Blue Swede\u2019 potato: Cultivation &#038; harvest of the blue potato variety\" \/><\/p>\n<p> The potato has a wide variety of colors, including the blue potatoes [Photo: photka \/ Shutterstock.com]\n<p> <strong>Note<\/strong> : There are a few other types of blue or purple potatoes. You can find out more about this in our special article on purple potatoes.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Growing_blue_swede_potatoes\"><\/span> Growing blue swede potatoes<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p> The blue potato variety can be planted in a normal bed, raised bed or in a flower pot. With us you will find general tips on how to plant your potatoes or how to grow potatoes in the flower pot. The &#39;Blue Swede&#39; is laid in the ground from the end of April to the end of May. The planting distance should be 30 to 35 centimeters in the row and 50 to 70 centimeters between the rows.<\/p>\n<p> So-called seed potatoes and not seeds are used to grow potatoes. There are numerous suppliers of &#39;Blauer Schwede&#39; seed potatoes, including organic ones, so that you have a large selection at your disposal. A nutrient-rich and potassium-accentuated soil like our Plantura organic tomato &#038; vegetable soil is a good start when planting potatoes. Because the soil is suitable for both the pot and the bed, it is up to you where exactly you want to plant your &#39;Blue Swedes&#39;. The blue potatoes germinate at a soil temperature of 7 to 8 \u00b0 C and can be planted from April. But it is also possible to let these germinate in the warm from March and only then to put them in the ground. This enables the &#39;Blue Sweden&#39; to be harvested earlier. It should be noted, however, that the sensitive germs do not break off when they set in the soil.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"maintenance\"><\/span> maintenance<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p> Of course, the &#39;Blauer Schwede&#39; potato has to be piled up and checked for pests. You can read more about correct potato cultivation in our special article.<\/p>\n<p> If you want to boost the yields of your blue potato, you can re-fertilize in June. For example, you can use a primarily organic fertilizer such as our Plantura organic tomato fertilizer. This is suitable for a wide variety of vegetables with a high need for potassium, especially if the soil is rather sandy and no potting soil has been used to improve it.<\/p>\n<p> The &#39;Blue Swede&#39; is easily susceptible to potato scab &#8211; a potato disease caused by the bacterium <em>Streptomyces scabies<\/em> . This needs oxygen to survive and here the resourceful gardener can use a trick that also includes the right watering:<br \/> In order to prevent potato scab, it is an advantage to water the potatoes very regularly in small doses, especially from the point where the tuber begins, i.e. before flowers appear. The scab-causing bacteria love oxygen and the water can fill the air pockets in the soil &#8211; the bacterium is inhibited in its development.<br \/> In addition, you should only chop a little so as not to bring more air into the soil.<\/p>\n<p> In addition, late-ripening varieties such as the &#39;Blue Sweden&#39; often suffer from late blight, triggered by the egg fungus <em>Phytophthora infestans<\/em> . By pre-germinating and thus an earlier harvest, you can counteract the fungal attack, since late blight only attacks the plants more strongly towards the end of the season. A varied crop rotation is also important. This means that you should not plant the &#39;Blauer Schwede&#39; potatoes or vegetables from the nightshade family &#8211; such as potatoes, tomatoes, physalis or aubergines &#8211; in the same bed every year.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Harvest_and_use_of_blue_Swedish_potatoes\"><\/span> Harvest and use of blue Swedish potatoes<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p> The harvest time for the &#39;Blue Swede&#39; potato is usually around August, making the blue potato one of the mid-early varieties to be harvested. The tubers have reached their harvest size after 130 to 150 days. This can also be seen from the plant&#39;s slightly wilting foliage. Among the blue potato varieties, the &#39;Blauer Schwede&#39; potato has the highest average yield. <\/p>\n<p><img decoding=\"async\" class=\"aligncenter\" src=\" \/wp-content\/uploads\/1d13b9ad8dffcd5a52538ecf655d38f8.jpg\" alt=\"\u2018Blue Swede\u2019 potato: Cultivation &#038; harvest of the blue potato variety\" \/><\/p>\n<p> The bright color also comes out under the bowl<\/p>\n<p> The floury to predominantly waxy blue potatoes can be used well as salad, jacket or boiled potatoes. The &#39;Blue Swede&#39; can also convince from the oven as fries or gratin with its strong taste.
