You Biquitous!

       Me no Biquitous; Ubiquitous!  I can't remember if we planted them Back & front - OR - One only & they emigrated to t'other.
       I found 2-3 assorted names, but settled on:-
"Anemone nemorosa  -  wood anemone
A dwarf herbaceous perennial to 20cm in height, with a slender rhizome and deeply cut leaves. Solitary flowers with about 7 white petals, sometimes flushed pink on reverse."
I had NO idea of other names beyond "Windflower" & what my warped sense of humour renders as a "Wooden Enemy" (OK YOU say/think it fast.)
"Other names.
Lady's Nightcap, Moonflower, Nightcaps, Old woman's Nest, wind-flower, wood Crowfoot,  wood windflower, blodyn y gwynt", 
NO prize is for guessing the Welsh name.
