Hi! This is my first time harvesting salvia seeds. I have found two types of seeds. The tiny black ones, and plumper, larger greenish-brown ones, that I assume are not mature. Will these larger immature seeds mature if they are already removed from the calyx? Can I put them in the same envelope as the mature seeds or will they contaminate them? I am a real procrastinator, and should've done this a long time ago as it is getting cold up here. Thanks for your help.
