In permutation of Gertrude Stein

A rose is not a rose not a rose

– Leonard Blumfeld

Totally Optional Prompts asked for Symbolic Poetry. This is one.

Note added in afterthought
Who knows what exactly Gertrude Stein had in mind with her triple rose ("a rose is a rose is a rose"), one of the most frequent quotes ever. I assume that she wanted to draw attention to the essence of what a rose is.
My permutation wants to emphasize the fact that roses are probably the most meaning-laden flowers ever – highly symbolic objects.
