Tasmanian Tree Fern, Peter Pan, Rotundiloba and European White Birch
I haven't been able to find much information on the following plants and trees: Tasmanian Tree Fern (Dicksonia Antarctica), Peter Pan (Agapanthus Africanus), Rotundiloba (Liquidambar Styraciflua), and European White Birch (Betula Pendula). Are any of them toxic to pets?
With the exception of producing mild stomach irritation, none of the plants you've listed are known to pose a serious toxic risk to animals. As with all plants, however, it’s always a good idea to discourage your pet from nibbling on them to avoid an upset stomach.
