American Groundnut - Tubers
(Apios americana)
We are extremely excited to offer American groundnut Tubers for the 2025 season! Also known as Hopniss, this native vine has a long history of indigenous use as a food crop and companion plant. The tubers, which range in size from a pea to a golf ball, are edible and have a nice sweet nutty flavor. They are easy to harvest by following the vine to where it meets the ground and unearthing the tuber chain. Above ground, the leaves and flowers are typical of those in the pea family, with wisteria-like leaves and beautiful mauve pink flowers in late Summer.
A nitrogen-fixer, this vine is often found in the wild along streambanks, or in wetlands, but we have grown it in conventional garden settings and upland meadows to great success. Planted below a trellis or even sunchokes, it will climb high and proud and encourage the plants around it to do so as well.
Each unit is a chain of tubers approximately 8” long. Plant into damp soil and keep moist until new growth emerges in late Spring.
Hardiness: Zone 3-9
Soil: Wet soggy soils to well drained loam
Light: Full Sun to partial shade
