Ah, but one thing is certain - they definitely won't be any use still in the seed packet. Go ahead, sow them - nothing to lose.

I Googled Tassel flower and the botanical name that came up was Emilia coccinea. Generally seeds remain viable for a short period of time--for many, not longer than two years. That said, you can sow them and hope for the best. As campanula suggested, they don't have the option of sprouting unless they're planted.

i agree with campy... whats to lose.. one pot.. and some media ...

whats the alternative.. throw them away??? .. i dont think so ...

or.. just sow them direct .... and then weed them all out.. when you forget what you did.. lol.. been there.. done that ...remembering in fall.. wondering what happened to them ... lol ...
