White Velvet Spiderwort. This gets great cobwebby silver-white foliage with light purple flowers nestled in the leaf axils. Likes it on the drier side thank goodness and is far hardier than we thought. This overwintered in the ground outside at plant maestro Brian McLaughlin's garden just down the road at 10 degrees one winter "although I mulched it" he hastened to add. The biggest issue for us is not so much the cold but adequate winter drainage because we can get some rain. It resents water-logging but is really quite easy and just very eye-catching as it looks more house plant the garden plant.
