Can You Buy Potato Seeds?

Yes, you can buy potato seeds — but the term “potato seed” actually refers to two different things: seed potatoes (small tubers) and true potato seeds (TPS). Understanding the difference helps you choose the right product for your garden and avoid costly mistakes.

Seed potatoes are what most home gardeners buy. They are whole or cut pieces of potatoes that sprout and grow into new plants. True potato seeds are real botanical seeds that grow inside tomato-like fruits on potato plants. Both are available, but they serve different purposes and require different growing methods.

What Are Potato Seeds?

In gardening, the phrase “potato seeds” is confusing because potatoes can reproduce in two ways.

Seed potatoes are simply small, healthy potatoes saved from the previous harvest. Farmers and gardeners plant these whole or cut into pieces, each with at least one “eye” (a bud). When placed in soil, they sprout and create a new potato plant. Almost all potatoes you buy for eating are from seed potatoes, not true seeds.

True potato seeds (TPS) are tiny, actual seeds produced by potato flowers. After flowering, the plant develops small green fruits that look like cherry tomatoes. Inside those fruits are dozens of tiny seeds. TPS is a relatively new option for home growers, but it has been used by breeders for decades to create new varieties.

Can You Buy Seed Potatoes?

Yes, and that is the most common way to start a potato patch. Seed potatoes are widely available from garden centers, nurseries, and online suppliers. They are sold by variety, size, and condition.

When buying seed potatoes, look for certified disease-free stock. Certified potatoes have been tested and are free from common potato diseases like blight, scab, and viruses. Avoid using grocery store potatoes because they may carry diseases or be treated with sprout inhibitors.

You can find seed potatoes in many types: early season (matures in 60–80 days), mid-season (80–100 days), and late season (100–130 days). Popular varieties include Yukon Gold, Russet Burbank, Red Pontiac, and Kennebec. Specialty growers also offer purple, fingerling, and heirloom types.

For a reliable supply, check certified seed potatoes on Amazon or your local garden center in early spring.

Can You Buy True Potato Seeds (TPS)?

Yes, but true potato seeds are less common and not sold in every garden store. You can order them from specialty seed companies that focus on TPS varieties. These seeds come in small packets with maybe 20 to 100 seeds.

TPS has a few advantages over seed potatoes. They are much lighter to ship, store longer, and carry less risk of soil-borne diseases. You can also grow unique varieties that are not available as seed potatoes. However, plants grown from TPS need more care at the start. You must start them indoors in trays, keep them warm and moist, and transplant them after frost.

Not all potato varieties produce viable true seeds, and the plants grown from TPS may not be identical to the parent plant. For that reason, TPS is best for experienced gardeners who want to experiment or save seeds for future breeding.

If you want to try TPS, search for true potato seeds online from reputable sellers like those specializing in rare or heirloom vegetables.

Where to Buy Potato Seeds?

You have several options depending on whether you want seed potatoes or true seeds.

For seed potatoes:

• Local garden centers and nurseries (best for picking out healthy tubers in person)
• Online seed catalogs like Burpee, Johnny’s Selected Seeds, or Gurney’s
• Farm supply stores (often sell in bulk)
• Farmers’ markets (sometimes sell heirloom varieties)

For true potato seeds:

• Specialty online seed companies
• Small farms that sell rare variety seeds
• Potato breeding programs (some sell TPS directly)

Timing matters. Seed potatoes are usually sold from late winter through early spring. True seeds are often available year-round, but you need to start them 8–10 weeks before your last frost.

Storing potato seeds properly is also important. Seed potatoes need cool, dark, humid conditions around 40–50°F. If you buy early, keep them in a root cellar or a cool basement. If you need a storage solution, consider a potato storage container that keeps them dark and ventilated.

How to Plant Seed Potatoes vs True Potato Seeds?

These two methods are quite different. Here is a quick comparison.

Planting seed potatoes (the easy method)

1. Choose certified seed potatoes.
2. Cut larger ones into pieces with at least two eyes each. Let cut surfaces dry for 1–2 days.
3. Plant pieces 4 inches deep, 12 inches apart, in rows 2–3 feet apart.
4. Hill soil around the plants as they grow to keep tubers covered.
5. Water consistently, but avoid waterlogging.
6. Harvest when the foliage yellows and dies back.

Planting true potato seeds (the advanced method)

1. Start seeds indoors 8–10 weeks before your last frost.
2. Use seed-starting mix in trays, pressing seeds lightly into the surface.
3. Keep soil moist and warm (70–75°F). Seeds should germinate in 7–14 days.
4. Provide strong light (grow lights or a sunny window).
5. Transplant seedlings outdoors after frost, spacing them 12 inches apart.
6. Hill the soil as they grow, just like with seed potatoes.
7. Harvest small potatoes about 90–120 days after transplanting.

Important: Plants from TPS often produce smaller potatoes the first generation. If you want full-size tubers, you can select the best ones from that harvest and replant them as seed potatoes the next year.

What Are the Best Potato Varieties for Beginners?

If you are buying seed potatoes for the first time, stick with widely available, reliable varieties. Here are three easy options.

• Yukon Gold – Medium-early, yellow flesh, buttery flavor, very productive. Good for boiling, mashing, and baking.
• Red Pontiac – Late season, red skin, white flesh, stores well. Tolerates a range of soils.
• Kennebec – Late season, white skin, disease-resistant, excellent for baking and fries.

For true potato seeds, beginner varieties include Clancy (a purple-skinned TPS that is harder to find but interesting) and Crop 101 (a TPS blend designed for home gardeners). Most TPS beginners should start with a mix rather than a single variety.

Common Mistakes When Buying Potato Seeds

Avoid these pitfalls to save time and frustration.

Buying grocery store potatoes for planting. Grocery potatoes are often treated with sprout inhibitors or carry diseases like late blight. Even if they sprout, you risk infecting your garden soil for years.

Not checking the variety’s maturity time. If you have a short growing season, do not buy late-season potatoes. Check the days to maturity and match them to your local frost dates.

Neglecting to buy certified disease-free stock. It costs a little more, but it gives you a clean start and higher yields.

Ordering true potato seeds too late. TPS needs a long indoor start, so schedule your order for at least 12 weeks before planting outdoors.

Storing seed potatoes in the refrigerator. Refrigerators are too cold and dry, which can damage the buds. Use a cool, dark, humid spot instead.

How to Store Potato Seeds Before Planting

Storage depends on the type.

Seed potatoes:

• Keep in a dark, cool place (40–50°F) with high humidity.
• Do not wash them before storage.
• Check occasionally and remove any that are rotting or sprouting excessively.
• If they sprout early, you can still plant them — just handle sprouts gently.

True potato seeds:

• Store in a cool, dry, dark place, like a sealed envelope in the refrigerator.
• Properly stored TPS can remain viable for 3–5 years.
• Keep away from moisture and heat.

Are True Potato Seeds Better Than Seed Potatoes?

Neither is universally better — it depends on your goals.

If you want a simple, reliable harvest, buy seed potatoes. If you enjoy experimentation and want to save seeds across years, try true potato seeds.

When Is the Best Time to Buy and Plant Potato Seeds?

• Seed potatoes: Buy in late winter to early spring. Plant 2–4 weeks before your last frost date. Soil temperature should be at least 45°F.
• True potato seeds: Order any time, but start indoors 8–10 weeks before your last frost. Transplant after danger of frost passes.

In mild-winter climates (zones 9–10), you can also plant a fall crop of seed potatoes in late summer. Check your local extension service for exact dates.

Can You Save Potato Seeds from Your Harvest?

Yes, but the method depends on what you want.

To save seed potatoes, simply set aside a few healthy, medium-sized tubers from your harvest. Do not wash them. Store them in a cool, dark place until the next spring. Do not save tubers from plants that showed any signs of disease.

To save true potato seeds, you need to let some potato plants flower and set fruit. Allow the green fruits (which look like small tomatoes) to ripen on the plant until they are soft. Harvest the fruits, mash them in water, and let them sit for a day. The viable seeds sink, while pulp floats. Rinse and dry the seeds on a paper towel. Store them in a cool, dark envelope.

Important: True seeds from hybrid potato varieties will not grow true to the parent plant. Only open-pollinated or heirloom TPS will reliably reproduce.

Final Tips for Buying Potato Seeds Successfully

Always start with a clear plan. Decide whether seed potatoes or true potato seeds suit your space, time, and experience level. Order from reputable suppliers to avoid disease and disappointment. Pay attention to variety maturity — match it to your growing season — and prepare your soil with plenty of organic matter and good drainage.

If you are new to growing potatoes, seed potatoes are the easier, more forgiving choice. Find a certified source, pick a well-known variety like Yukon Gold or Kennebec, and follow the planting steps outlined above. For more detailed growing guidance, consider a potato growing guide that covers soil prep, watering, pest control, and harvesting.

Whether you buy seed potatoes or true potato seeds, the key is to treat them with care from purchase to planting. Healthy starting material leads to a healthy harvest. So yes, you can absolutely buy potato seeds — just know which type you need and where to find quality stock.
