We've finally cleared our main garden of all our inherited plants, except for the yucca. Assuming this is common yucca / Yucca filamentosa, it is native to just south of here, like Virginia, so I think of it as helping the plant move north ahead of global heating. https://en.wikipedia.org/wiki/Yucca_filamentosa
Also, I'm told that previous owners have tried to kill this plant multiple times and failed dramatically (it looks very healthy). I try not to pick fights I expect to lose.
