PREORDER Groundnut - Apios americana - Improved LSU Cultivar

(No reviews yet) Write a Review

Groundnuts are a native, vining, nitrogen-fixing, perennial vegetable with edible tubers. The tubers are delicious and store exceptionally well.


This is an improved cultivar of Apios americana from Louisiana State University's breeding program. They were selected for increased productivity and larger tuber size.


​We offer 2 different size options. 10 medium tubers or 20 small tubers. They are all clones, with the same potential to create quality thriving plants. The smaller tubers just take a bit longer to get established.


Groundnut orders will be shipped after harvest if fall of 2024. If there is a preferred shipping date mention it in the 'comment' section at checkout.

Shipping begins after harvest on Oct 7th 2024

Product Overview

LATIN NAME: Apios americana
COMMON NAMES: Groundnut, Hopniss, Indian Potato, Potato Bean, Hodoimo

NUTRITION: Tuber- Has three times the protein as potatoes. They are a good source of calcium and iron, and there is evidence of anti-cancer activity.
FOOD PREPARATION: They are often cooked as you would a potato. They can also be baked into chips or dried and ground into flour.  I like them in stews and with oven roasted meats. 
HISTORY: Important food to Native Americans. They would harvest it in the wild and transplant the tubers to create stands closer to their settlements. Has been cultivated in Japan for 100 years.
EDIBILITY SEASON: Once established, Groundnut can be harvested at any time of year. Tuber size after two seasons of growth will be substantially larger than after one season of growth.
OTHER USES: Nitrogen-fixer, shelter for beneficial insects, nectar for beneficial insects, ground cover

PLANTING: When working with a new species, I typically recommend planting them in multiple different locations to see what works best for them in your climate and context. Groundnuts can be planted at any time of year. However, if you want to harvest a sizable crop they need to be planted in early spring, or in the fall of the previous season. Plant them 12-18 inches apart. I find they do well along fence rows and in more moist locations on my farm.  

MAINTENANCE: Once a stand is established they will maintain themselves. I don't find weeding necessary. In my experience they co-exist well with others and use other plants as a trellis. They will be less productive if they don't get enough water.  I smother my plantings in woodchips to retain moisture and make harvesting easier.  

HARVEST: Dig with your favorite implement and enjoy. I use a potato fork. If the planting has lots of woodchips they tend to grow their tubers just bellow them, requiring very little digging. Leave behind some tubers to ensure the stand will be maintained.
