I do like the idea of adding "Grown for foliage," but I still find the "good growing season color" description a bit vague. Would it make sense to reword that to indicate that the growing season color makes a nice contrast with normal green foliage? Or something like that? Because I think that just adding the "grown for foliage" box may not solve the problem of people checking the "good growing season color" box when it's not really appropriate. Just a thought.
