Nothing is so beautiful as spring— When weeds, in wheels, shoot long and lovely and lush; Thrush's eggs look little low heavens, and thrush Through the echoing timber does so rinse and wring The ear, it strikes like lightnings to hear him sing; The glassy peartree leaves and blooms, they brush The descending blue; that blue is all in a rush With richness; the racing lambs too have fair their fling.
What is all this juice and all this joy? A strain of the earth's sweet being in the beginning In Eden garden. Have, get, before it cloy, Before it cloud, Christ, lord, and sour with sinning, Innocent mind and Mayday in girl and boy, Most, O maid's child, thy choice and worthy the winning.
The Summer, the divinest Summer burns, The skies are bright with azure and with gold, The mavis, and the nightingale by turns Amid the woods a soft enchantment hold: The flow'ring woods, with glory and delight, Their tender leaves unto the air have spread, The wanton air amid their alleys bright Doth softly fly, and a light fragrance shed: The Nymphs within the silver fountains play, The Angels on the golden banks recline, Wherein great Flora, in her bright array, Hath sprinkled her ambrosial sweets divine; Or, else I gaze upon that beauteous face, O Amoret! and think these sweets have place.

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.
