Frullania jackii: A Tiny North American Liverwort Worth Knowing
If you’ve ever taken a close look at the bark of trees or moss-covered rocks in your garden, you might have encountered a fascinating little plant without even realizing it. Meet Frullania jackii, a native North American liverwort that’s part of an ancient group of plants that have been quietly going about their business for millions of years.
What Exactly Is Frullania jackii?
Frullania jackii belongs to the liverwort family, making it a distant cousin to mosses and hornworts. These aren’t your typical garden plants – they’re some of the most primitive land plants on Earth, and they’ve got some pretty unique characteristics that set them apart from the flowers and shrubs you’re used to.
This particular liverwort is a small, leafy plant that grows as a terrestrial species. Rather than putting down roots in soil like most plants, it prefers to attach itself to solid surfaces like tree bark, rocks, or even decaying wood. Think of it as nature’s way of creating living wallpaper!
