Vera,
I can't see the pics:( Some people's photos are considered pop-ups by my computer.
Anyway, you might have hibiscus syriacus seeds. The white w/red center variety is traded a lot. In fact I have some.
Another white w/purple centered flower traded often is a type of datura.
The link is a great seed identification site.

Here is a link that might be useful: The Seed Site

Thanks except I have Hibiscus not Datura which is a whole different family (Solanaceae) all together :)
I have emailed the trader but she's not replying.

H. syriacus, Rose of Sharon, seeds have small hairs all along the edge.
Did you have any luck with the Seed Site webpage?

Vera,
Sorry You must have a flower photo showing. I thought there were just seeds I couldn't see that is why I mentioned datura. I thought the trader might of made a big mistake, not you : )

That's ok Remy :) I just have seeds showing above... I did go to the Seed Site before posting here (it in my favorites) and Rose-of-Sharon (H. syriacus) is the only seed shown at the site. They definatley are fringed on the edges on heart-shaped seeds, but I doubt the trader took the time to remove these because they are just TOO clean.
I guess I'll just see what I get huh? Suprise, suprise LOL!

I guess what I was really trying to find out is if all Tropical seed looked the same; all hardy the same; all annual the same. That way I would at least know what type of Hibiscus I was dealing with and treat accordingly.

These seeds look like the ones I just harvested from my tropical hibiscus, H. rosa-sinensis.
