The edile tubers are sometimes gathered from the wild for local use.
South-western N. America - mountains of Mexico and south to Peru and Bolivia.
Prefers a light well-drained loam with added leafmold[
]. Succeeds in an ordinary, reasonably moist soil in a sunny position with some shelter[
The following use is for the closely related C. tuberosa, but is also probably appropriate for this species[
Tubers - cooked. Rich in starch[
], but with a fairly bland flavour.
Seed - sow March in a greenhouse. The seed usually germinates in 4 - 5 weeks at 20°c[
]. When they are large enough to handle, prick the seedlings out into individual pots plant them out in late spring or early summer, after the last expected frosts.
Division in early spring. Make sure that each portion has at least one growing bud[
Cuttings during the growing season. Very easy[
