i love them- definately more flavorful than pecans (more pita to pick, certainly, but for lazy winter nights in front of the fire...) almost a maple-syrup kind of taste. very rich.
my ds picked up so many when he was just learning to toddle! (i had to be careful not to let him put any in his mouth.) last fall tho', we had no harvest (just one of those 'off' years), or i'd offer to send you a few to plant. the tree looks geared up to have a bumper crop again tho' next fall (i hope!)
we have shagbark hickories, carya ovata. (fwiw, i've sent some to various places like scotland, iceland, netherlands... hope they are doing well. none to nz yet tho'!)
