Here is a gem by Naomi Long Madgett
Out of Time
It wasn't ready for the frost,
That small improbable bud that didn't ask.
The season's limitations
But dared to be bright
Anyhow.
Full of delight as a puppy,
Or a new poem,
It took the sun for granted,
Accepted Indian Summer for the real thing
And went on exuding sweetness
Even after its brown-edged petals fell.
(Nobody bothered to tell her
She wasn't a summer rose.)
