Yes, company says sow, and place outdoors for spring germination.
I do have a styrofoam cooler that I could place the box.
Package just says Lilium Selected species mix. ( from Plant-World in UK).
I also started two martagon packets:
one just says "pink" and the other says "Inschriach rose".
The martagons will be kept warm for three months then into 'frig.
Another batch of martagon seedlings are soon to be placed 'frig for their second "winter".
One box is "alba" and the other is a mix. I am running these drier as they will be chilled soon.
And I know there is little nutrients in vermiculite so either dilute fertilizer or transplant to soil.
These last martagons are in soil.
