Proboscidea althaeifolia (Unicorn Plant/Devils claw)

This plant has bedeviled native plant enthusiasts and propagators here in the Southwest, people with more experience than I.  Scarifying seeds with hard coats is standard practice for many southwestern US natives.  I've never found seed, but I do have two plants in my college garden beds that I carefully transplanted as tiny seedlings.  I don't recommend transplantation, and once P. althaeafolia is established, its deep and huge tuber makes it untransplantable (for those of us who don't own backhoes).
