Alandra,I never noticed the curvature of the petals,thanks.Cheers Whittler,I now weeds are only plants in the wrong place but oxyzilous (spelt wrong)I've aways called them weeds because you can spray them pull them out and they flourish anyway,you are right though,thank you.

as well as the cheerful bright colour, Vince, I also like the curvature of the petals of the flowers.
