The Catalpa

The catalpa’ s white week is ending there
in its corner of my yard. It has its arms full
of its own flowering now, but the least air
spills off a petal and a breeze lets fall
whole coronations. There is not much more
of what this is. Is every gladness quick?
That tree’ s a nuisance, really. Long before
the summer’ s out, its beans, long as a stick,
will start to shed. And every year one limb
cracks without falling off and hangs there dead
till I get up and risk my neck to trim
what it knows how to lose but not to shed.
I keep it only for this one white pass.
The end of June’ s its garden; July, its Fall;
all else, the world remembering what it was
in the seven days of its visible miracle.

What should I keep if averages were all?
