Thanks everyone for your input.
I just went out to see if the tuber had by any chance started growing again. From your answers I figured if there was no growth I'd put it into semi-dry storage for a bit.
Nothing had broken the surface if the soil, so I gently uncovered the tuber. I'm glad I did. No growth, but I discovered about a third of the tuber had turned to mush. I must have damaged it when I was trying to break apart what I had thought was a dirt clod/root ball.
I cleaned it out as best I could, then used spray from the hose nozzle to get a better clean. I put it under cover to dry. As I write this I'm thinking I'll go back out and put it into a baggie of dry peat. The peat will help to kill fungus and bacteria. Not sure the tuber is salvageable at this point. Damn!
Guess I'll have to sprinkle the remainder of my seed and try again!
Hi, Danita! And yes, the seed came from you in the Piggie Swap, but not directly. I received the seed in the 1:1 section of the swap. BTW, my member name on that site is RedLeopard. Thanks for having offered up the seed! From what I had read of it's heat tolerance, sun preference, and hummer attractiveness, I had long wanted to try B. boliviensis. I don't know why I didn't go after those seed in the main swap, but was sure glad when I received them!
