Geum macrophyllum “Large-leaf Avens” Rosaceae

This little forest flower is common throughout moist bottomlands and subalpine meadows here in the PNW. It can be easily distinguished from other yellow-flowered Avens by its massive leaves and reflexed sepals (they’re not visible behind the petals here). Avens characteristically produce adorable heads of achenes that look like tiny sea urchins. In its cousin, Old Man’s Whiskers (Geum triflorum), these achenes have a long feathery tip and look like wisps of smoke.
