I saved some seeds from an heirloom tomato last fall. It took me 2 hours to find where I'd put them, but in the end I got a fantastic germination rate, they're a few weeks old now.
I have extras to unload if anyone is interested, really they should be in the ground by now.
I meant to get involved with a community garden this spring, but it has flown. I wish I had space for a proper garden!
