im looking for plants to start growing for my tortoises, and i was wondering if any certain type of hibiscus is not reccomended for tortoises. im considering buying hibiscus syriacus rose of sharon. would this be ok or is there other reccomendations? i wanted to find the types of hibiscus that are hardy and can take colder temps, since i live in new york. let me know what everyone thinks or knows! i have seeds from carolina pet supplys that i plan on using. what are other people growing every year for there tortoises?
