    Does anyone have experience with seed treatments and/or tips for germination of Solidago squarrosa?

    We have worked at CREW with other Solidago species from the US (e.g. S. ohioensis, S. shortii, S. odora), and cold moist stratification for 6 to 8 weeks worked pretty well. When we had low germination was due to empty seeds.

    I haven’t worked with Solidago squarrosa, but my Solidago spectabilis and Solidago velutina ssp. californica seed collections germinated well (71% and 75%, respectively), on agar with no treatment.

    Looks like Kew had good results at 25C – http://data.kew.org/sid/SidServlet?ID=47724&Num=1DJ
