What plant looks like dill leaves but has small flowers?

Question

I have a flower that grows no taller than 2 feet high, with small bell like flowers that come in purple, pink, and white. When it first started growing, I thought it was dill. It was even growing next to dill and early in the season it was hard to tell the difference. Every year I get less of these flowers, so this year I collected the seeds in hopes to get more flowers back.

Also, the hummingbirds love the flowers. So, what I want to know is what kind of flower it is and when should I plant the seeds (spring or fall)? Thanks

If you could send me a picture, that would be helpful in identifying the plant. You can just send it to the address on the address notification email.
