My best on this one? Purple-stemmed or swamp aster Symphyotrichum puniceum. var. puniceus, a wonderfully common native species.

“When we’re on our knees, rooting around in the soil … what we’re learning are the fine, specific details of our home place, the things that make it unique. …This alertness is, I think, the key to finding a way to live on this earth with spirited wonder and mindful humility –necessary approaches if we’re to begin the crucial work that is ahead: the work of healing the planet. We need people to connect with their home places and learn about them and understand them and see and feel and know what they’re doing to them, and what’s happening to the earth. We need stewards and nurturers and people who care. We need gardeners." -
