Arr, thanks folks, I'll be polishin me halo for a bit after that endorsement.. No, not everything is poisonous to us on the list, nor to the rabbits, but I just found the introduction to the list which should have gone first, so here goes:
While the term “Rabbit-proof” with regard to plants is used (and is popular with garden centres and online suppliers etc.) what they actually means is “rabbit-resistant.” All plants, when they are young and tender are worth a nibble to a hungry bunny. Even “lords and ladies” plants are not rabbit-proof when they put out young, lush shoots – and they contain a burning acid in their sap! Tree bark is a fairly good deterrent, as are very dense thorns, and since rabbits obviously don't climb trees, tall shrubs and bushes are naturally resistant – but even so, slender young, green stems need protection. This is why climbing plants and vines are popular in rabbit areas, and species (wild) roses, some of which are far more woody and thorny e.g. Rosa Spinnosisima tend to be more popular than the glamorous hybrids grown in towns. Again, however, it only takes a nibble to snip through the base of a narrow stem and the whole plant is gone – so a bit of netting around a young, soft plant may be worth the effort. I'm not entirely sure about tree and plant roots. Some gardeners report rabbits digging out the roots of saplings and other new plantings (especially tuberous rooted perennials) when other green stuff is scarce. Perhaps they are just digging burrows – but I'd be on my guard. I have read that sinking a ring of chicken wire into the ground (to a depth of 6-8 inches) around a newly planted specimen will stop them digging out roots.
If I think a plant may be toxic I've put a note by it, but I have limited knowledge of toxicology, and you'll probably recognise other plants that are toxic on the list. This is only significant to mention here because some plants avoided by rabbits are avoided precisely because they contain something toxic or indigestible!
