Not a yellow or blue iris
that flowers in a cup right through the winter
not a pepper tree
that throws shadows the whole time
but to me you are
purple-blue morning glories
that folds open with the sun,
trailing everywhere
and when the dark days come,
with rain falling almost unstoppable
your grow densely
and with the first sunshine
there are flower upon flower.
