Horsemint (Agastache urticifolia) Plants in Wawona Meadow
Yarrow is well established in the medium-sized-flower category, yet it's dwarfed by the Horsemint in this scene. Wawona Meadow is apparently the Matanuska Valley of Yosemite; besides the supersized Horsemint, I've seen eight-foot-high Cow Parsnip here and Washington Lilies poking holes in the ozone layer.
