Rough estimate on location and abundance. A collection of them growing amongst a blackberry bush and other weeds. I'm sorry I should have taken better photos of the flowers a few weeks earlier when I first noticed them.
Kind regards, Roy.
Without measurements of leaflet length and width and a side on photo of the flower so I can see the teeth on the calyx at the base of the petals, I cannot determine the subspecies. The bases of the leaves where they join the stem are out of focus so I am not completely sure the species is sativa.
