potato/freeze?

this evening holds some promise as my second batch of seed potatoes form oregomn were on the front porch when i came home and the mailbox contained a small but mighty package from the potato introduction station on sturgeon bay wisconsin that has germplasm for isla caucacha and nordland potatoes as wellas the primitive cultivar negra ojosa...i've already planted wild potato seeds on campus and if those turn out well we will have a small representation of potato morphology...nothing approaching the huge variety of potatoes...but a decent morphological representation...there's a freeze warning in effect again tonight so i went out to campus to cover the teosinte again ( and stop off to see the coaach )...it's return was improbable and i want to get it through another full season...if the roots develop well enough perhaps, with luck, i can coax more seasons out of them...a forlorn hope prehaps but this season is a bonus so why not hope for more? the bottom two photos show that the chinese yams have found the uprights for the trellis...nearly as ferocious as the jerusalem artichokes, it will be interesting to see how they develop...the season is rolling along...lots to see...lots to do.
