SRGC Seed-To Plant or Not To Plant

Seeds requiring vernalization as a pretreatment don't need to freeze. They
just need a minimum number of days below 40F, which is easy to provide in a
small container or baggie with seeds, damp paper towel (or sphagnum moss or
coco-peat for instance). Once sprouted they can be carefully planted into
soil. Most respond quite well, but some need daily temperature
fluctuations, so coming out of the fridge and returning at night. Not sure
about Erythronium.

Spring growing species can still be planted now. Autumn growers can wait
until Autumn. They're unlikely to germinate before then, and risk rotting
over the summer if damp, in soil.
