I was over at my mom's apartment and I did a little seed gathering. It seems like I will have far more of a couple things than I can use. I will already be going to the post office tomorrow; all but one of the seeds are tiny enough to send in a regular non-padded envelope and should be small enough to survive the rollers. I'll take a chance on the other. It comes with it's own fluffy "parachutes". I'll add a little bit of extra cotton or something to hopefully increase the odds.

So for 2 people who can respond here and then email me their address by morning, I'll send the following.

Petunia exserta, >100 seeds

Calceolaria mexicana, >20 seeds

"Eupatorium sordidum", >20 seeds
This is actually an unnamed Bartlettina species

The Bartlettina/Eupatorium seeds are the ones that are not as tiny. They were harvested today, but I don't know how efficient the plant is at making viable seeds.

Finally, the next were not harvested today, but last year. They are actual even tinier than all the others. I don't know if they would need any special treatment to germinate:

Trachelium caeruleum 'Hamer Pandora' , hundreds of seeds.

All of these are from Annie's Annuals, which makes links to pictures and descriptions easy...

I'll send these two the first two people who post here and email me their address. Again, I'm sending these unpadded (slight padding for the Bartlettina/Eupatorium) and do not need to be reimbursed for one stamp each.

All are perennials with the exception of the Calceolaria, which vigorously self-sows. I think that maybe the Bartlettina/Eupatorium and the Trachelium prefer cooler summers, but I don't know.
