Description

Ships mid-April thru May.

Your order contains 5 plants. A gorgeous lilac-purple sweet potato with gourmet flavor. This Asian-type variety has a dry, firm texture that we love. Like most Asian types, the flesh is medium-low in sweetness but rich in flavor, making it one of the best purple varieties we've found. While similar in color to Okinawan purple sweet potatoes, this variety is noted to be more productive in northern climates.

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

Sweet potatoes are a long-season crop, requiring 90-120 days of warm temperatures to mature. Plant outdoors after all danger of frost has passed, when soil temperatures are at least 60 F. In northern climates, using black plastic mulch can help warm the soil and speed up growth. 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

Plant sweet potato slips 12-18 inches apart in raised beds or rows mulched with plastic or a thick layer of straw. Plant slips 2-3 inches deep, making sure that the roots and lower stem are buried while keeping the leaves above soil level. Do not skip mulching! It is essential for weed suppression, soil warmth, and moisture retention. Space rows 3-4 feet apart to allow room for the vines to spread. Water thoroughly after planting.

How to Grow

Sweet potatoes need consistent watering while young, keeping the soil moist but not waterlogged. As the vines mature and spread, they become more drought-tolerant, so you can reduce watering to every few days. Fertilization is generally not needed, as too much nitrogen results in leaf growth over root development. Avoid disturbing the roots while the plants are growing. Lilac Beauty sweet potatoes are generally low-maintenance, but they can attract wireworms, flea beetles, and sweet potato weevils. Keeping the plants mulched and maintaining good soil drainage can help prevent pest issues.

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.
