They should still be okay. But any way you look at it, why not give them a try? They shouldn't take too long to germinate.

Freezing will not hurt the seeds and you may have a zillion or two plants that grow from the seeds that got away during the winter. :o)

In addition to the gazillion seeds I have been harvesting :)

Thanks for the info!

My thoughts too...If you had a morning glory vine...don't worry...this year you will have plenty that pop up ...I love Morning glory...

OH YES!
You grow 1 morning glory plant, and you've got'em for years in massive doses! I have them growing into established plants and whatever is climbable. They're like an infestation.
So in answer to your question and to add more graphics to the previous responses, pitch the mold - start seeds only if you want to sell the plants (and/or dig up all starters that have self seeded)to gain a profit or help control the vine population - and if you want less next year, pull down plants before seed pods dry and open up to drop 4-5 more seeds that will require repeated maintenance.
I'm learning this again with a wormwood that shot a hundred babies from the mother root. - aargh!
good luck.

Thanks for all the responses. I am just getting into seed trading/exchanging so I thought about saving some of the seeds for that but I didn't want to send anybody a bunch of dud seeds.

I also thought about collecting my morning glory seeds to sell, then discovered that the sale of these seeds may start to be monitered. Apparently it's the latest 'fad' among young people. The seeds provide a similar "experience" to hallucinogenic mushrooms when ingested. To save myself any trouble, I decided not to sell any to someone I didn't know and just keep the rest for my personal garden.
