^ I think that was actually a poem Maa-chan wrote back then (not the one shown't above but the one about each member being a flower petal that will become a new flower when put together after Michishige is gone) not literally Michishige giving the members flower petals.
EDIT: I think you are talking about this interview:

But that's meant in a metaphorical sense. Not that Michishige actually gave them flower petals.
