If you've mistakenly spelled "seltuce" instead of the correct term, "celtuce", don't fret! Here are a couple of suitable suggestions. "Celtuce" refers to a variety of lettuce grown for its thick stem, resembling celery. Some other alternatives that may have been intended are "selvage" (the edge of woven fabric) or "septice" (a potential misspelling of "septic" referring to a system that manages wastewater).
