Magnolia Grandiflora germination time?
I purchased a batch of Magnolia Grandiflora seeds back in January. I live in a suburb of Seattle and we experience Zone 8 conditions during winter with extended springs.
I planted the seeds outside in late January at the same time I planted a few more in a pot on a southern exposure windowsill. In early February, I planted a few more seeds in one of those mini-greenhouses.
None of the seeds have germinated as yet. I did not expect the seeds planted outside to sprout, but I am surprised that even the ones indoors (in warm humid conditions) have failed to show any progress. Is the success rate with Magnolia seeds very low? How long can I expect seeds to take to germinate?
The seeds were purchased from a seller on Amazon who claims that they were pre-stratified. I did not stratify or scarify them, just plugged them into pots and/or seed starting mixture.
