Title: Information on edible tubers of hog potato from Austin
Answered by: Barbara Medford

QUESTION:

I inquired a while back about hog potato or Hoffmannseggia glauca. You gave me some information on the plant but no information on when the plant produces the edible tubers. Also how long does it take to produce the tubers after the seed germinates? Thank you,

ANSWER:

We found the previous answer  on Hoffmannseggia glauca (Indian rushpea) to which you are apparently referring. We suspect the the reason we didn't give you this information the first time around is that it was not available in our research resources. We did find a couple more websites that talk about the edibility of the tuber (mostly, as indicated by the common name, by rooting pigs).

Here are two references that did not appear in the original answer that might give you some more information:

Southwestern Arizona Wildflowers

Kansas Wildflowers and Grasses - this may give us a clue as to why no one is much interested in studying this plant, as it is referred to as "an aggressive noxious weed." Since it is a member of the Fabaceae or pea family, it does propagate by seeds and is a perennial. The swollen tubers are part of the system that permits this plant to spread, so we are assuming if the plant in question has been germinated from seed, and not tubers, it would probably be a year or more before that plant was mature enough to begin manufacturing the tubers and expanding the area of the plant.
