places, on the edges of woods, beneath hedgerows and in shrubberies.
It has an extensively creeping rootstock, stems rising to about
a foot, and smooth, oval, evergreen leaves. The beautiful golden
flowers, three inches across, have a great number of very prominent
stamens, united at the base into five bundles. July to September
is the time of flowering.
