Yucca filamentosa

Opinion
"
This is a plant I have had in my own garden, I put it down to inexperience since when it is in flower it is stunning. That said the rest of the time it looks as if it belongs in an arid, rock strewn environment: which my garden is not. Once planted it is hard to remove since it travels. I dug mine out, shoots reappeared, dug those out, it came up in the lawn, those I mowed, where it came up in the driveway I parked the truck on it; it finally succumbed. For a chuckle read what Michael Dirr has to say with regard to Yucca in his book Manual of Woody Landscape Plants.
