Trees & roses

Perhaps a tree really wants roses to be its fruits.
Perhaps roses truly want to be hats for trees.
And what does perhaps want?  By the way, is that "wish" or "lack?"
And, yes, the water is a mirage.  Most poems are like that, too.
Now consider the elusive artichoke. Yup, roses grow on trees;
if a poem were a vegetable, it would be an artichoke.
