A common-milkweed (Asclepias syriaca) umbel, painted with the bubble-chamber project's
own wet renderer (src/render/watercolor.js) driven by a new umbel generator
(src/milkweed/umbel.js). The conceit that made it fit: a milkweed umbel is a radial
event — a hidden central node, pedicels radiating like tracks, each blooming into a five-pointed
star at its tip. The bubble chamber's vertex and δ-ray spray, restated in botany; life wearing the
shape of the particle event. Same pigment physics as the plates — Beer–Lambert subtractive optics,
the wet edge, cold-press granulation, wet-into-wet bleed — only the geometry and the palette change
(sap green, quinacridone rose, a pale corona crown that barely tints the paper). Deterministic from
seed; herbarium caption from the shared archive-identity system.

The recreations
Milkweed Bloom — the recreation: a domed umbel of pink florets, pale-crowned, buds toward the rim, leaves splayed behind. milkweed · cream · MONARCH-3320Asclepias — a second specimen, same medium, a fuller cluster. milkweed · cream · ASCLEPIAS-7781Prairie — a rounder dome; the wet-into-wet bleed unifies the florets into one pink haze. milkweed · cream · PRAIRIE-5562Dewy — the medium turned wet: high wetness and bleed, soft edges, on cool blue-grey paper. A misted morning. milkweed · cool · wcWetness 1.5 / wcBleed 1.4 · SWAMP-1190Dry-brush — the opposite craft: drier, crisp wet edges, granulation turned up, on warm sepia. Late-summer, going to seed. milkweed · sepia · wcGranulate 1.35 / wcEdge 1.2 · AUTUMN-4408
