After several years of trying to rid our front flower bed of yucca, I have come to the conclusion that this wretched plant should be officially classified as a nuisance. A demonic garden pest that only the most inexperienced of gardeners would ever attempt to cultivate, it should be erradicated from the face of the earth. Seriously. Let's just raze the entire planet six feet deep to ensure that we get all those nasty tubers that spread like a cancer through otherwise good soil.
I would sacrifice every daylily, coneflower, daisy, shrub and bulb, even my precious little blue anemones to be ridded of it for good. Okay, well maybe I wouldn't go that far. But I am not-very-seriously considering transplanting all my other plants and bringing in some heavy equipment.
