I saw a delicate flower had grown up two feet high

I saw a delicate flower had grown up 2 feet high
Between the horse's paths & the wheel track
Which Dakin's & Maynards wagons had
Passed over many a time
An inch more to right or left had sealed its fate
Or an inch higher. And yet it lived & flourish[e]d
As much as if it had a thousand acres
Of untrodden space around it — and never
Knew the danger it incurred.
It did not borrow trouble nor invite an
Evil fate by apprehending it.
For though the distant market-wagon
Every other day — inevitably rolled
This way — it just as inevitably rolled
In those ruts — And the same
Charioteer who steered the flower
Upward — guided the horse & cart aside from it.
There were other flowers which you would say
Incurred less danger grew more out of the way
Which no cart rattled near, no walker daily passed.
But at length one rambling deviously
For no rut restrained plucked them
And then it appeared that they stood
Directly in his way though he had come
From farther than the market wagon —
