Thanks for your responses to my questions. I tipped the Oxalis bowiei out of its pot to see if there was any growth. Nothing yet, but the bulbs seem healthy. The only other oxalis that I think would bloom early would be oxalis fragrans. I got those last year mid September and it seems like they were up in a couple of weeks and bloomed in October. I didn’t get much growth out of my Oxalis bowiei last year, and no flowers.
