Name Origin for "Sedum" or "Stonecrop" Plants:
"Stonecrop" is from the Middle English and literally means "sprouting from the stone," a reference to the plant's commonly being seen growing amongst stones (which provide the drainage that stonecrop plants crave). "Stonecrop" doubles as the name of the family to which the genus, Sedum belongs.
"Sedum" itself derives from this same observation of where stonecrop plants tend to grow. It comes from the Latin, sedere, meaning "sit" -- as in "sitting" atop the stones.
