Solidago ontarioensis, Ontario Goldenrod

This very tiny species of goldenrod came to me as seeds from the Ottawa Wildflower Seed Library last fall. From what I can find out about them online, they seem to be a very small, clump forming species particularly well adapted to growing in rocky settings.

Photos from the University of Waterloo Asterae Lab website, one of the few places I was able to find information on this species.
