I remember a discussion on foxgloves this summer on NonMet though I didn't follow along. I just remember it because I read a post or two at the time I was trying to transplant some in my own garden.
This is a lovely poem and it is nice to see a free verse opening the event. I think I remember the author but am not sure.
Yes, I agree that the parentheses are done very well and that the poem pivots at that point and provides an unexpected end (one that couldn't happen without the non-parenthetical build-up), but there's too much crescendo and not enough FORTE.
