I have a few "American Heritage: Celebrate Your State!" charts from Creative Keepsakes (Betty Haddad Shelton), each of these are a state outline, with the state flag, bird, flower and other key symbols. As far as I can tell the company appears to be out of business (phone numbers don't work), although there are some charts on ebay. I might be willing to sell my charts, as I doubt I'll ever stitch them - I have Arizona, California, and Oregon (unopened) and a slightly used Utah chart.
One of my goals for this year is to start designing embroidery patterns and in particular a pair based on some WPA woodcarvings at the state library of the Oregon state bird and plant. When I do, they will be on my (new) website
Orange Rug Yarn Stitchery If you go to the NetState page for
Washington's State Flower there are all sorts of state flower and bird references, including a book of state flower cross-stitch charts.
