I opted out of the online seed swap.
I frequently save Sweet William seed (dianthus barbatus)by color. Invariably the 'red' are mostly pink spotted, the 'white' turn out mostly pink spotted and the pink are frequently white or red, just like Mendel predicted.
Once in a while there's a really stunning auricula eyed dianthus by chance.
I understand about the thrill of a whole bunch of seeds from afar. I've already ordered from Thompson and Morgan some fresh seed that I thought would enhance my little species bunches next spring.
