I know that you asked specifically about Hermanns, but I too feed our Sulcata both fresh and dried hibiscus leaves as well as any blooming flowers. Hibiscus is now inside the sunroom for winter, so it tends to drop a lot more dried leaves than normal. Sully takes care of this "problem" for us.
A question.
How does one dry flowers?
A couple of members have mentioned wanting some and whenever I've tried to dry them they just get wilted and moldy.
My Redfoot will eat them fresh or funky. They just don't care. The leaves too.
