Why milkweed is called milkweed. I’d forgotten how profusely they bleed milk!
Sticky, white latexy sap is toxic and can damage skin (and eyes). But golly, how gorgeous: the whole weird, wonderful plant.
And how neat that the butterflies which eat the leaves become just as toxic and nasty-tasting to predators.
By this logic, I should taste like Marmite, toast, and tea.
