Ours Russian tortoise has eaten the little green stuff on the top of the stalks.
Next day, when putting the stalks themselves on the dish together with dandelion leaves she didn't eat anything from that dish.
Somewhat concerned, our daughter fed then dandelion leaves by hand. Later, I removed everything from the dish, that is the fennel stalks including the dandelion leaves as they might have absorbed the strong smell from the fennel.
Having filled the dish with fresh dandelion leaves, she immediately started eating from that dish. : victory:
So, it looks like that she only likes the green stuff from the top.
An interesting article - but without mentioning fennel what could be rather a Mediterrenean plant - is this one:

But I still haven't tried it as I first need to become more knowledgeable about weeds and the other plants - poppies and the like - in general.
I always have been crap on most plants and only know palms.
