Potatoes can be pre-sprouted before planting, which is commonly done in Europe, but not much in the U.S. for some reason. The reasons for doing so are quicker maturity of the potatoes, heavier yields, and the development of stronger sprouts that are not broken off so easily.

Where to Buy Purple Potatoes Seed?

Seed purple potatoes can be purchased from a variety of sources.  Your local nursery might have them, as well as seed companies.

When you buy your seed potatoes, it is a good idea to purchase non genetically modified versions (GMO), organic sources.  These will become a food source to your family, and you want the healthiest types as possible.  At the end of this post, I’ll list one recommended source.

Planting Purple Potatoes

To pre-spout seed potatoes get some flats, or open top crates and fill with potting soil. Cut the seed potatoes so each section has at least one eye. Place the cut potatoes with the seed end up, in the soil.

Place the flats in a warm (70 degree) place with medium level light.  Do these a couple weeks before you plan to plant outdoors. Potatoes do best with a soil PH of 5.0 – 7.5 range.

If you prefer to plant purple potatoes directly in your garden, plant them 6-8 inches deep into your garden soil, and 12 inches apart.   Cut your seed potato with a clean knife into smaller pieces about 2 inches square.  Make sure this square section has at least 1 bud with it.  Place your cut seed potato in the ground, with the cut side down, and the bud portion pointing upwards.

When the plant shoot is about 10 inches tall, use a shovel and mound up dirt around the plant, covering the stems about half way or so.

Planting purple potatoes can be done in the early spring.  They can tolerate some light frost, but if you know a heavy frost is due, you’ll want to give them some frost protection. One easy way to do that is by using a frost protection blanket, specifically for gardening.

Keep your potato plants well watered while it is flowering, immediately after that, and during the summer season.   This is when the plant is growing the tubers, and need for water is greatest.

Later in the year, the foliage will begin to turn yellow are starts dying back.  Stop watering at this point.  It helps them start to cure in preparation for harvesting.  You will harvest them 2 or 3 weeks after this point.

To harvest your purple potatoes, choose  a dry day if possible.  Take a garden fork and carefully lift the potatoes up.  If you have dry weather, let the potatoes cure by leaving them to lay in the dirt for 2 or 3 days.  This allows for better storage, as it allows the skins to mature.  If you have wet weather, let them cure unwashed in a dry covered area.

 To store your purple potatoes try to find an area that is cool, dark and well ventilated.  If you don’t have a root cellar, perhaps a basement would work.  Ideal temperatures would be around 40°F.

  • 2 T. olive oil
  • 1/4 teaspoon crushed red pepper flakes
  • 1 tablespoon chopped capers
  • 1 teaspoon chopped tarragon

Heat 1 T. olive oil and sauté the onions and mushrooms about 5 minutes, until just tender and the onions become translucent.  Put into a bowl.

Heat 2 T. olive oil (in the previously used pan) and fry the purple potato wedges until browned, reduce heat and cook until tender, about 10 minutes.  Sprinkle with salt and pepper.  Add the onions and mushrooms back to the pan, then add the remaining ingredients.

Sauté the shallots in olive oil until tender and caramelized, put aside in a bowl.

Brown the bacon in the same skillet, until just cooked, not crispy.  Cut into smaller pieces.

Grease a shallow baking pan, and layer half the potatoes.  Add the shallots, then layer the remaining purple potatoes over top.  Pour the cheese gratin sauce completely over the potatoes.  Top with bacon and grated parmesan cheese.  Bake at 350 degrees for 40 minutes.
