From the CO2Science archive: We’re not sure if Sphagnum fallax is what John Lennon had in mind when he wrote the opening lines of Come Together but this old flat-top has something like ju-ju eyeballs during part of its growth phase. It seems to be native all over the world and likes marshy areas. And CO2. In 2018 there was an experiment in which Flat-topped bogmoss was exposed to an extra 300 ppm CO2 and grew 98 percent bigger after 13 weeks. Grooving up quickly, you might say.
