Original Cinderella 99bx, vintage 1999, frozen and germinated in 2015. This lot still has a 95-98% germ rate.

They can be frozen, you just have to germinate them as soon as you take them out of the freezer. U don’t want to take them out and wait a week to use them, or thaw them and re-freeze them again. I prefer to store them in a sealed container, in a dark, cool, dry place.
I don´t doubt you, and over anything i want to believe, since my collection is about to get bigger and bigger, i need to know that they will sprout even after a long time in storage. Nice pointers @BigSur!
I have never froze seeds because I have not ever needed to. However what comes to mind are the landrace indicas that grow in areas where it gets below freezing.
I am just gonna put them in airtight bags with rice and off to the freezer, but not all of them, there are some i'm leaving outside... Thanks @BigSur!
i had seeds stored outside in my garage (sensi black domina + the freebies) for 7 years and they went through temperature extremes +40 to -40 and none of them germinated after, 30+ seeds
exposure to moisture is what kills the seeds, not being frozen IMO. I've read that freezing is best for very long-term storage where the seeds are not taken in & out of the cooler often. Leave those in the refrigerator instead.
I've stored them in the fridge in a glass jar with silicon dessicant to lower the humidity into the single digits. So far getting near 100% germination after 15 years.
yes or the silica cat litter will work good too i think, i save all those silica packs now for reuse
I agree... it's cold in Upstate New York now... I have them in a spare room that's about 50 degrees Fahrenheit all the time... While cataloging them I didn't want to take them in and out of the refrigerator because of temperature fluctuations. I hesitate to put them in the freezer because of that as well. What is your opinion?
I was reading from this site that someone had stored his seeds without Refrigeration in a fishing bait box... And they popped
I agree that they should be kept cool at all times
I keep mine in small glass jars, in the shade, at room temp.
Some believe in refrigeration.
I don't expect to get more than 3-5 years shelf life out of them. But I wouldn't be shocked if they last longer.
I agree with freezing if long-term storage... 10 years plus... Otherwise Refrigeration is probably prudent... But I agree... They are seeds and if kept at cool temperature... Most will pop
