In some ways, my favourite volunteer plants are brambles, with their beautiful nectarful flowers as well as gorgeous fruits.
But I also love scarlet pimpernel and veronica / speedwell for their flowers & gentle ground-cover.
Then there are the volunteer, self-seeding edibles such as salsify, and corn salad.
I love accepting the ways volunteer plants can enhance the local ecology.
I have absorbed from many sources, including Robin Wall Kimmerer, the concept of vigorous volunteer plants - of cultivated, or uncultivated origin, for which I can learn the virtues & most harmonious configurations - to displace the concept of "weeds".

"“There’s no such thing as a weed.” This concept, from renowned Japanese botanist Dr. Tomitaro Makino, reminds us that every plant in nature has its proper name and purpose. "
