oooooh..........bunny heaven would be a nice mix of long grasses and some added clover , alfalfa and things like plantains and dandelions!!
but if youre talking garden plants then a lawn (organic of course) and herbs, fruit trees ,willow, a birch tree is always nice i think.....um....perhaps some briar fruit like blackberries or the spineless hybrids like loganberries or tayberries? i grow these near the rabbit pens and they are really robust and the buns love the leaves and the fruit and they can climb over arches or fences etc. many a time the leaves of these briars have saved my buns from runny tummies as they are astringent. :wink:
and getting back to what you asked....poisonous stuff.....well theres such a lot. its easier sometimes to start from scratch and only put in what you know is safe. theres a list somewhere.....not sure if its on here or somewhere else.....i'll go look.
