I started really getting into gardening a few years ago; and have been trying to learn as much as possible.

I feel like I still have a lot to learn.
But, from what I understand so far, you should be pretty successful saving seeds from any crop that is not a Hybrid variety.

I have been thinking about getting one of those "emergency cans" of seeds to stick in storage as a backup... but, you can also find "standard" non-hybrid seeds on the store shelves too. So, you don't necessarily have to jump into one of those $40 cans right away.

My local news station ran a quick story last night, saying that there may be a shortage of seeds this year.
That was the first I have heard of that.
Of course, now a shortage is probably guaranteed in my area, since the TV news has "rang the bell".
