Edible Uses

Edible Parts: Root
Edible Uses:

Tubers - raw or cooked[2, 5, 12, 17, 63, 100]. A very pleasant food with a flavour somewhat between a sweet potato and hazelnuts, with a hot aftertaste of radish[115, 183, K]. We have never detected this hot aftertaste, and feel that the flavour is reminiscent of brazil nuts[K]. There is only one tuber on each plant, this is rather small and difficult to harvest, but the size could probably be increased by cultivation[115, K].

Cultivation details

Never found on alkaline soils in the wild[12]. See the plants native habitat for other ideas on its cultivation needs. This species responds to cultivation by producing larger tubers[115]. With careful selective breeding it is probably possible to produce a much more productive plant[K]. For polyculture design as well as the above-ground architecture (form - tree, shrub etc. and size shown above) information on the habit and root pattern is also useful and given here if available. The plant growth habit is a clumper with limited spread [1-2].

Plant Propagation

Seed - sow spring in a cold frame. Germination is usually quick and good[K]. Prick out the seedlings into individual pots as soon as they are large enough to handle and plant them out when in early summer. It is also possible to sow in situ, though this requires a lot more seed to produce the same amount of plants from a protected sowing. Division in late summer as the plant dies down.

Other Names

A bit concerned about the identification as there are a number of poisonous umbellifers. Trying to find some positive means of identification

   Tue May 15 2007

This is a useful link, Lynne: http://www.countrylovers.co.uk/wfs/pignut.htm Or you could dig one up, with the tuber, and identify it that way.

   Tue Sep 4 2007

They have very fine leaves and flower before most umbellifers, and yeah ... the tuber is the sign its a pignut!

Phill   Fri Jun 19 2009

I have found pignut with four plants growing from the same tuber. i have tried them in Yorkshire, North Devon and Salisbury and the hot peppery after taste was obvious in North Devon, milder in Yorkshire and not detectable in Salisbury.
