Willow is incredible stuff. It has been planted and used by humankind for centuries; steeped in history it's uses can be traced back to Celtic times.
Uses of coppiced willow rods are almost endless: baskets, hurdles, crab and lobster pots, eel traps, creels, coracles, hampers, outdoor sculptures, dens, mazes, living fences, bent willow furniture, coffins, garden arbours, charcoal, river stabilization... It would be hard to make the list exhaustive.
But that's not all: if left to grow on willow can be managed to produce logs for open fires or log burners, it can be chipped for boilers, it can be planted to filtrate sewage...
It truly is incredible stuff.
