I wish I could tell you what they are ...
But after a couple hours of searching online flower guides, I'm still stumped! I'll continue to research, but in the mean time, these are yet to be identified. If you have any idea or even a stab, please comment!
This is actually Thalictrum thalictroides
Hope you enjoyed!
P.S -- I found out that the 'pine tree' regenerating pine needles is actually a Tamarack Tree, and to shed and regrow needles annually is part of the normal cycle for this kind of tree. It is quite an interesting tree. Perhaps I'll expound a little more when the needles have grown a little more. ;-)
