We've already established the nature of poppy dust, and it does seem to be one of Mulan's favorite weapons. and as we've seen, it is effective in taking out strong witches (and giants, and probably ogres as well). And it would do well to add to the Oz worldbuilding that they have finally gotten around to fleshing out.

A journey to the poppy field may be a small part of the episode, and Dorothy handing the flower to Ruby may be nothing more than showing the flower type to make sure it would work for their purposes.

I wouldn't read anything more into that picture without some additional context. My thoughts exactly.
