Globeflower / Trollius chinensis

These Globeflowers are so bright and cheery. Photographed this one at the Reader Rock Garden on 24 July 2013. They are members of the Ranunculaceae family, and the open flowers have prominent stamens.

"Trollius is a genus of about 30 species of plants in the family Ranunculaceae, closely related to Ranunculus. The common name of some species is globeflower or globe flower. Native to the cool temperate regions of the Northern Hemisphere, with the greatest diversity of species in Asia, trollius usually grow in heavy, wet clay soils.

All trollius species are poisonous to cattle and other livestock when fresh, but their acrid taste means they are usually left uneaten. They are, however, used as food plants by the larvae of some Lepidoptera species including Silver-ground Carpet." From Wikipedia.
