Hi fellow Floridian and Bun parent!
I was about to create a post regarding this. Unfortunately there isn’t really a solid resource out there on edible wilds for bunnies, so I start with human safe greens to forage because according to the house rabbit society website: if it’s safe for humans it’s safe for buns.
Here is what I have so far that is safe:
Crespis Japonica: Seasonal potherb also known as Hawksbeard, False Hawsbeard, or Youngia.
Stachys floridana: know as Florida Betony or rattlesnake root. Closely related to Stachys affinis which is considered a delicacy and sells for $150 a pound!
Daucus Carota & Pusillus: Edible Wild Carrots or Queen Anne’s lace
One thing that is edible for humans but not buns is Oxalis, which can be confused with clover. Also known as sorrel. It is too high in oxalic acid.
I don’t think any maple wood is toxic to rabbits to chew, put I’ve never heard of anyone feeding rabbits tree leaves because it’s not a food the would normally forage.
Elder flower leaves and stems to me would be toxic as they are far too high in alkaloids…but there seems to be conflicting information online. Because many fruit bearing shrubs and trees have toxic aspects, I would just avoid completely.
One of the most cost effective and enjoyable things is to start your own garden. Even growing herbs in pots is a great way to give your bunny (and you!) access to yummy things to nibble. When I weed my I make sure to save any edibles to supplement his hay.
Please share anyother wild bun safe edibles you are able to find!
