Apparently Blackberry lilies are a species that’s warm-germinated and is advised to be sown midwinter indoors??- or maybe not. There’s a bit of contradiction info source to source.
“Iris domestica is reputed to have a very short seed shelf life“

SHIT NOT GONNA HAVE A REPEAT ON THE FERN SPORE INCIDENT; TIME TO GRAB THE SEEDING TRAYS!!!! Not risking it, this is nowhere near midwinter but Gato’s not risking it.
