I'm the one to thank you - you've pointed out something that takes a lot of thought and observation to notice. I have been much better at watering so far this summer, so the combination of sun/extra water also adds up here. I also have seeds from a cultivar that poly'd all season last year in sun, while this year in shade has produced no polys. But, I never saw the possible pattern to it until you pointed it out! I will also make sure to re-arrange a few - like sending that last one back into sun with good watering - and follow up on what happens, though it may take another season to do so. Well worth finding out if background poly genetics may have some interaction with sun and level of hydration!
