I've been searching all over the Internet, including the wonderful tortoiselibrary, to try and find out if ornamental gingers are toxic to tortoises. That would be things like Alpinia zerumbet (Shell Ginger), Costus speciosus (Crepe Ginger), Curcuma elata (and C. Longa), Globba wintii, Hedychium coronarium (and coccineum)- aka Butterfly Ginger, Kaempfera pulchra (and K. rotunda and K. zerumbet). any experience? Thoughts? Thanks!
