This beautiful Grand Prize has been in my garden 2 years now. I can't recall whether it was planted last year or the year before. I do recall it was a fall special and already going dormant and brown. I was looking over the garden yesterday and was startled to see something that looked like a hosta, but which I never planted, to my knowledge. Is that darker green plant with the pointy leaves that is next to Grand Prize a hosta? If it is, does anyone know what it is? Much obliged!
