The force that through the green fuse drives the flower Drives my green age; that blasts the roots of trees Is my destroyer. And I am dumb to tell the crooked rose My youth is bent by the same wintry fever.
The force that drives the water through the rocks Drives my red blood; that dries the mouthing streams Turns mine to wax. And I am dumb to mouth unto my veins How at the mountain spring the same mouth sucks.
The hand that whirls the water in the pool Stirs the quicksand; that ropes the blowing wind Hauls my shroud sail. And I am dumb to tell the hanging man How of my clay is made the hangman’s lime.
The lips of time leech to the fountain head; Love drips and gathers, but the fallen blood Shall calm her sores. And I am dumb to tell a weather’s wind How time has ticked a heaven round the stars.
And I am dumb to tell the lover’s tomb How at my sheet goes the same crooked worm.
What is beauty but a breath? Fancy’s twin at birth and death; The color of a damask rose That fadeth when the north wind blows. ’Tis such that though all sorts do crave it, They know not what it is to have it— A thing that sometime stoops not to a king, And yet most open to the common’st thing: For she that is most fair Is open to the air.

How this picture is made
What a fractal is
A fractal is a shape that keeps its pattern when you look closer. Coastlines, trees, shells, and weather do this. The large form and the small form are the same kind of thing. A poem can be drawn that way. The shape of the whole comes from the shape of the lines.
Primunia is the name for the source of that order: the pattern under the pattern, already there in a tree, a shell, and a verse.
How the boundary is drawn
The number under the picture is the poem constant. It is read from the build of the lines: their length, how uneven they are, the size of the stanzas, the share of vowels, and the way the lines end. A new word moves the number when it changes that build. The same poem always gives the same number.
Drawn on its own, that number sits in a quiet part of the plane, and most poems would look like the same soft disk. So the number is carried outward along its own direction until it meets the edge of the Mandelbrot set, where the shape turns sharp. The picture is the Julia set of that meeting place.
Each point on the canvas is folded again and again by one small rule. Points that stay near the rule form the dark interior. Points that rush away become the coloured bands. The hue comes from the poem constant, and the brightest bands turn toward gold. Change the length of a line, the stanza, or the vowel share, and both the number and the picture move.
What the branching signifies
Branching draws the poem as a tree. Each turn follows a line, and every smaller branch repeats that pattern. A longer line reaches farther. The letters at the start of a line bend the next turn. A higher share of vowels opens the branches wider.
The trunk takes its colour from the poem constant and warms toward gold at the tips. When the poem has more than one stanza, gold forks leave the trunk. Each fork is a stanza beyond the first, up to three. The tree divides where the poem divides. One stanza remains a single trunk.
