Been reading some interesting stuff here... was about ready to plant a
black locust grove until I read in Peterson's Field Guide on
Eastern/Central Medicinal Plants that BLACK LOCUST (Robina
pseudo-acacia) -> 'All parts are toxic - even honey derived from flowers
is said to be toxic.'  Any thoughts / comments from someone w/ first
hand experience would be greatly appreciated.  The long shelf life
sounds great, but this raises another question!
