Eric,
I went to the accentsforhomeandgarden.com website to look at their porterweeds. It's the coral porterweed (Stachytarpheta mutabilis). When you look at the flower color, it's coral. They list it that it grows 5 feet tall x 4 feet wide.
I've never ordered from them before, but maybe next spring I'll look at their website and see what they offer.
