Is it raining, little flower?

Is it raining, little flower?
Be glad of rain;
Too much sun would wither thee;
‘Twill shine again,
The clouds are very black, ’tis true;
But just behind them shines the blue.

Art thou weary, tender heart?
Be glad of pain;
In sorrow sweetest virtues grow,
As flowers in rain.
God watches, and thou wilt have sun,
When clouds their perfect work have done.

—Lucy Larcom
