Bet: Do you know Gordon Bok's "Turning Toward the Morning?" It has this verse:

It's a pity we don't know
What the little flowers know.
They can't face the cold November;
They can't take the wind and snow.
They put their glories all behind them,
Bow their heads and let it go;
But you know they'll be there,
Shining, in the morning.

Seems to me your Mom knew that, too.
