Queen Anne’s Lace

Wild Carrot, or Bird’s nest weed, or (my name) Chalice of Stars:
Watching a QAL in various stages of unfold is its own special treat. It starts as small unfolding wad, with just a hint of purple as the bundle unfolds. As the flower head matures it flattens, then swells, moving from the shape of small pancake, to a pin-cushion.
Then there are the blooms themselves. Like wheels within wheels. You might notice the small bloom-cluster moving away from the pack. It mirrors the overall shape of the larger flower-head.
Even weirder, after getting all big an flowery, the flower pad folds back in, going back into something of its pre-boom shape where it becomes a virtual seed nursery. (Addendum coming)
