What kind of flowers can I plant in my garden?

I need the flowers to be colorful. I want an assortment and they can't grow more than 6 inches tall. They will be in full sun. Don't matter if annuals or perennials. It could be a mix of both. They will be growing along the fence in front of the house where everyone can see. I usually plant marigolds. Love those. Any ideas would be welcomed. Thanks.

no more than 6"??? that's tough! portulaca, allyssum, lobelia..
Reply:No more than 6 inches, hmmm? Dwarf Dahlias are always my favorite, they come in almost every color and will stay within your height requirements. They are very easy to grow too.
Reply:There are many kinds of sun flowers that come in various colors that are great in the sun , Marigolds are nice too and maybe some pansy's :O}
