I've watch'd you now a full half hour, Self-pois'd upon that yellow flower; And, little Butterfly! indeed I know not if you sleep, or feed. How motionless! not frozen seas More motionless! and then What joy awaits you, when the breeze Hath found you out among the trees, And calls you forth again!
This plot of Orchard-ground is ours; My trees they are, my Sister's flowers; Stop here whenever you are weary, And rest as in a sanctuary! Come often to us, fear no wrong; Sit near us on the bough! We'll talk of sunshine and of song; And summer days, when we were young, Sweet childish days, that were as long As twenty days are now!
Busy, curious, thirsty fly! Drink with me and drink as I: Freely welcome to my cup, Couldst thou sip and sip it up: Make the most of life you may, Life is short and wears away. Both alike are mine and thine Hastening quick to their decline; Thine's a summer, mine's no more, Though repeated to threescore. Threescore summers, when they're gone, Will appear as short as one!

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.
