Joy~ ( Greater Celandine )
" weed" / wildflower but i think they are pretty. After all " a weed is just a flower that is growing in the wrong place!" Thank you Neva. ;)
Chelidonium majus (greater celandine; in Europe tetterwort, although in America the same name refers to bloodroot) is a herbaceous perennial plant, the only species in the genus Chelidonium. It is native to Europe and western Asia and introduced widely in North America.
While the greater celandine belongs to the poppy family, the lesser celandine belongs to the buttercup family. ( thank you Anna and Irene for the identification!! )
