Though I didn't cut my douglahs back to just a stump last year, I still did a significant pruning before bringing them indoors. They did start flowering and producing pods earlier in the season than the new douglah I added to the batch this year - likely because they didn't first have to complete the job of growing up. That said, my rocotos...... ah, the rocotos. I think they do prefer cooler weather, because although the overwintered ones started blooming madly in the spring, not a single pod stuck until the fall, just like their first year, and just like the new one I got this year. So variety may impact your experience.
