WE are the roadside flowers,
Straying from garden grounds, —
Lovers of idle hours,
Breakers of ordered bounds.
If only the earth will feed us,
If only the wind be kind,
We blossom for those who need us,
The stragglers left behind.
And lo, the Lord of the Garden,
He makes his sun to rise,
And his rain to fall like pardon
On our dusty paradise.
On us he has laid the duty, —
The task of the wandering breed,—
To better the world with beauty,
Wherever the way may lead.
Who shall inquire of the season,
Or question the wind where it blows?
We blossom and ask no reason.
The Lord of the Garden knows.

Bliss William Carman
