While the rattail is putting on its crazy little fireworks display, the Euphorbia did something we’d not witnessed before. It was super-hot last weekend — just a few degrees shy of 100° — and we kept hearing this funny popping-snapping sound all around the garden, like firecrackers past their “use by” dates. It was the Euphorbia seeds exploding out of their bracts, banging into each other in flight. Audible, projectile reseeding. Craziest thing I ever saw in the garden, and I’m not sure why we’ve never seen them do this before. I can only guess it had something to do with the heat.
