Hibiscus planting and storing of seeds?

I live in northern Illinois and just recieved some hibiscus seeds from a friend. Should I spread them now or wait until later this fall or even the spring? If I should wait, what is the best way to keep the seeds? Do they require shade or sun, or are they pretty versatile?

Plant in the spring after all danger of frost is past. They love sun. Store in a cool dry place and not in a plastic bag. Old spice cans or jars work well.
