The 4-letter word that means "plant" or "root" and follows bladder, St. John's, and slipper in the names of flowers is Fern.
Ferns are a group of seedless vascular plants that have a modified horizontal stem called a rhizome that grows underground. The rhizome acts as a storage organ and produces new fronds or leaves above ground.
For example, there are ferns that resemble tree-like palms, small aquatic ferns that float on the surface of water, and ferns that resemble four-leaf clovers. Ferns have a diverse range of forms and can be found in various habitats.
