I'm going to have to see if my 'wabash' puts out PBF.. If not, then I've got the imposter. Couldn't find any pictures of it in the garden that showed the foliage. But if it does have PBF, then I've got lots to share. It's been growing in dry rocky soil where the gophers roam, and seemingly not bothered by it.
The surest sign that intelligent life exists elsewhere in the universe is that it has never tried to contact us.
