"They ate the chrysanthemums last year, just because they were something new. They just can't taste yummy."
Actually.....depends on the variety! I remember reading about battered and fried chrysanthemum leaves Japanese style. Google says all chrysanthemums are edible but some taste better than others.

I was surprised to read that evening primrose is also an edible green. I hope I never need to know that! It would be too odd to start eating those. And I'm still marveling at the fact that sweet potato leaves are edible.
