The conflicting info on bindweed is probably because several different plants are commonly called "bindweed," so some may be safe while others aren't. The best bet is to get a positive identification on the scientific name (genus and species). Then you'll know for sure.
Wisteria is on the House Rabbit Society's list of poisonous plants.

Bluebells are also poisonous. All plants with bulbs (tulips, daffodils, lilies, etc) are poisonous to rabbits -all parts of the plant.
The apples should be safe in small amounts. You just don't want to let them have more than a few nibbles, as the high sugar content can be a problem. They also shouldn't eat the seeds, due to the cyanide.
