The upkeep time — a critical metric in GG — was minimal, as these are California Poppies: a native, drought-tolerant wildflower. It only needs a bit of help to compete against imported grasses and weeds. This patch started as just a few scattered flowers. I invested a few 5 to 10 minutes sessions, in winter and spring, to cleaning out the weeds. Once blooming, a few minutes each week dead-heading poppies keeps the bed looking great for several weeks. And by incorporating the time into a stretching break in a bicycle ride, the overall time hit was small and working with flowers is a nice break on a ride! People walking by really liked it. Not enough to stop and help right then, but I decided it would make a great community project: getting people to adopt small parts of their favorite trails.
