I use it for the goats, and also as compost activator, and to add to my smelly liquid for the tomatoes (sheep dung, nettles and comfrey if I remember). Got mine form Organic garden catalogue, they only sell it in spring as root slips, grows very well. My hens have so far not vandalised it, but the voles have tunnelled around and under it (and everywhere else in the garden, field...). great stuff, and beautiful flowers (for the bees too).
