Description

Ships mid-April thru May.

Your order contains 5 plants. A delicious old-fashioned sweet potato with golden-red skin and moist, flavorful bright orange flesh. The short, bush-like vines produce good-sized clusters of these earthy jewels, making them easy to dig and well-suited for garden growing. Once widely grown for about 75 years and first mentioned in 1868, this rare variety nearly disappeared in modern times. We are proud to help bring it back into circulation and onto America’s dinner tables. A tasty piece of history, possibly introduced from Brazil.

Please consider these terms before ordering live plants:
Most plants will be 3" to 7" in height. All plants will ship promptly as available. Please make sure you are ready for your order in your growing zone, as these young, tender plants generally have no resistance to cold.

Growing Guide

When to Grow

Plant Pumpkin Yam sweet potatoes after the last frost, when soil temperatures reach at least 60 F. In cooler climates, try using black plastic mulch, raised beds, or row covers to warm the soil and extend the season. Since sweet potatoes are frost-sensitive, be sure to check your local last frost date before planting. If you’re not sure how to find your area's first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Hydrate the slips by soaking the roots in water or wrapping them in a damp paper towel before planting. Loosen the soil 12 inches deep, form 8-inch-high mounds, and space slips 12-18 inches apart in rows 3-4 feet apart. Plant slips 2-3 inches deep, ensuring the roots and lower stem are buried while keeping the leaves above soil level. Mulch with plastic or a thick layer of straw to suppress weeds, retain moisture, and warm the soil. Water thoroughly after planting and keep the soil moist as plants establish.

How to Grow

Water consistently in the first few weeks to help plants establish. Once the vines spread and mature, they become more drought-tolerant, and watering can be reduced to every few days. You can fertilize with a low-nitrogen fertilizer (such as 5-10-10) about 3-4 weeks after planting to encourage tuber development. Since vines spread widely, ensure they have enough space.

How to Save Seeds

  • Sweet potatoes are not propagated by seeds, but rather by saving tubers over the winter in a cool, dark place to replant the following spring.
  • Be sure to select the most healthy tubers for replanting.
  • Follow this comprehensive video guide to curing and storing sweet potatoes over winter.

FAQ

How do I know when Pumpkin Yam sweet potatoes are ready to harvest?

Harvest when the leaves and vines start to yellow, usually 90-120 days after planting. Dig carefully to avoid damaging the tubers.

Can I eat Pumpkin Yam sweet potato leaves?

Yes, the young leaves and shoots are eaten as a cooked green, commonly in stir-fries and salads, with a mild, spinach-like flavor.

Why is mulching important for Pumpkin Yam sweet potatoes?

Mulching with straw or plastic suppresses weeds, retains moisture, and warms the soil. Without mulch, weeds may compete for nutrients, and vines can become difficult to manage.
