Blue Potato

Blue Potato: The Colorful and Antioxidant-Rich Spud

Get ready to add a splash of vibrant color to your garden and your plate with the amazing blue potato! These fascinating tubers, with their striking blue or purple skin and often matching flesh, are more than just a visual treat. Imagine digging up a harvest of these unique potatoes, ready to bring a pop of color to your favorite dishes. Growing blue potatoes is a fun and rewarding experience, and their impressive nutritional profile makes them a healthy addition to your homegrown bounty.

Think about the delightful surprise of slicing into a blue potato and revealing its beautiful interior. These aren’t your average spuds! Their slightly nutty flavor and creamy texture make them incredibly versatile in the kitchen. Plus, the vibrant hues of blue potatoes come from anthocyanins, powerful antioxidants also found in blueberries and other colorful fruits and vegetables. Let’s explore why you should grow these captivating blue potatoes, how to best enjoy their unique qualities, and the simple steps to a successful harvest.

Why Grow Blue Potatoes?

  • Visually Stunning: The unique blue or purple skin and flesh add an exciting visual element to your garden and your meals.
  • Nutrient Powerhouse: Blue potatoes are rich in antioxidants, particularly anthocyanins, which may help reduce inflammation and support overall health.
  • Delicious and Versatile: Their slightly nutty flavor and creamy texture make them perfect for a variety of cooking methods.
  • Fun to Grow: Cultivating these colorful tubers is a unique and engaging gardening experience.
  • Good Storage: Like other potatoes, blue potatoes can be stored well under the right conditions, allowing you to enjoy your harvest for an extended period.
  • Heirloom Varieties Available: Many blue potato varieties are heirlooms, adding a touch of history and unique characteristics to your garden.

How to Eat Blue Potatoes?

  • Roasted: Roasting brings out their natural sweetness and creates a slightly crispy exterior while keeping the inside creamy. Their color remains beautifully vibrant when roasted.
  • Mashed: Imagine a bowl of vibrant blue or purple mashed potatoes! Adding a touch of vinegar while cooking can help keep their stunning color.
  • Potato Salad: A blue potato salad is a showstopper! Their color adds a fun and unexpected twist to this classic dish. Combine them with red and white potatoes for a patriotic or simply eye-catching salad.
  • Fries and Chips: Turn your blue potatoes into colorful and delicious fries or chips. Their unique hue will make snack time extra special.
  • Steamed or Boiled: These simple cooking methods highlight the blue potato’s natural flavor and help retain its color, especially when microwaved or steamed just until tender.
  • In Soups and Stews: Add chunks of blue potato to soups and stews for a pop of color and a satisfying texture.

Growing Blue Potatoes

Blue potatoes are typically grown as annuals, planted from seed potatoes (which are actually tubers with sprouts). Here’s how to cultivate these colorful wonders:

  • Planting: Plant seed potatoes 1-2 weeks before the last expected frost in spring once the soil has warmed up. Choose a location with full sun (at least 6-8 hours daily) and well-drained, loose soil that is slightly acidic (pH 4.8-6.5 is ideal)—plant seed potatoes about 4 inches deep and 12 inches apart in rows 3 feet apart. You can plant small seed potatoes whole or cut larger ones into pieces, ensuring each piece has at least one “eye” or sprout. Allow cut pieces to air dry for about a day before planting to help prevent rot.
  • Soil: Blue potatoes prefer loose, well-drained soil rich in organic matter. Amend your soil with compost before planting to provide essential nutrients. Avoid heavy nitrogen fertilizers, as this can encourage excessive foliage growth at the expense of tuber development.
  • Watering: Water deeply and consistently, especially during tuber formation. Aim to keep the soil evenly moist but not waterlogged. Reduce watering when the plants begin to yellow and die back towards the end of the growing season.
  • Fertilizing: Apply a balanced fertilizer at planting time. You can also side-dress with a nitrogen-rich fertilizer when the plants are about 6 inches tall to encourage healthy growth.
  • Light: Full sun is crucial for a good harvest of blue potatoes. Ensure they receive at least 6-8 hours of direct sunlight daily.
  • Hilling: As the potato plants grow, hill the soil (mound soil around the base of the stems) to cover the developing tubers. This prevents them from turning green because of sun exposure and encourages more tuber production. Hill the plants a few times during the growing season. You can also use straw or mulch for hilling.
  • Pest and Disease Control: Keep an eye out for common potato pests like Colorado potato beetles and aphids. Use row covers or organic insecticides if necessary. Ensure good air circulation to help prevent fungal diseases like blight and scab. Select disease-resistant varieties if these have been a problem in your area.
  • Harvesting: You can harvest “new” potatoes (small, tender potatoes) about 7-8 weeks after planting when the plants begin to flower. For mature blue potatoes you plan to store, wait until the foliage begins to die back, usually about 90-110 days after planting, depending on the variety. Harvest carefully using a digging fork or spade, being careful not to damage the tubers.
  • Curing and Storage: After harvesting, cure the blue potatoes in a dark, humid place for 1-2 weeks to allow the skins to thicken. Then, store them in a cool (40-50°F or 4-10°C), dark, and well-ventilated place for several months.

Tips and Tricks for Blue Potato Success

  • Choose Certified Seed Potatoes: Purchase certified disease-free seed potatoes from reputable sources to ensure a healthy start.
  • Rotate Crops: Avoid planting potatoes in the same location year after year to help prevent soil-borne diseases.
  • Remove Flowers: Some gardeners recommend removing the flowers from potato plants to direct more energy towards tuber development.
  • Companion Planting: Consider planting blue potatoes with companions like beans, cabbage, or marigolds, which may help deter certain pests.
  • Maintain Soil Moisture: Consistent soil moisture is important for good tuber development, especially during dry periods.
  • Experiment with Varieties: There are several blue potato varieties available, such as ‘Adirondack Blue’, ‘All Blue’, and ‘Purple Majesty’. Try different ones to find your favorites!
