Eating Sunflower Leaves...

I have found a few online resources that one can eat mature sunflower greens. Does anyone here have experience with this?
If so, how about Jerusalem Artichoke leaves?

My sunflowers have leaves like sand paper, was this online resource saying to cook them before eating?
If you ate a majority of the leaves it seems like it would cut down on the productivity of the flower and seed.

I once saw where someone was buying sunflower heads at the market for the inner leaves around the flower head. i think they were immature flower heads...i'll try to find out more. Otherwise, like Zack says, the leaves don't look very appealing:)

This site says yes..........I knew about and love YOUNG sunflower sprouts with leaves............they also say mature leaves and flower BUDS! I might try some buds for lunch...they says steamed like artichokes....HOW TO EAT SUNFLOWERS
"Pick the flowers when they are in the bud stage. The buds taste similar to artichokes. Pull off the bitter green around the bottom of the bud. You may steam sunflower buds or boil them in water for a few moments and serve with butter."

Yeah, definitely a cooked green...

I am talking with Green Dean about it here

The geese adore the mature leaves, the goat refuse them.

I went ahead and made steamed flower buds from my helianthus Maximiliani and was really impressed with the flavor and texture. I will definitely be doing this more. Chalk it as a native perennial vegetable.

I picked a bunch of leaves and have them frozen. If I can un thaw and cook with good results I will be stocking a bunch of these sunflower greens for winter.

Next I will try various preparations of the root which is said to have been eaten raw, boiled or roasted by plains Indians.
