Hard to find! Rarest of the green tardianas! This is Kurt Tramposch's 'Kryptonite', which he found in a batch of 'Blue Wedgwood' some time ago. Some think it is another green 'Halcyon', others that it may just be 'Blue Wedgwood'. We don't know. Whatever it is, it is one of the most beautiful greens with deep dark shiny leaves, and it's attractive right up until the first frost puts it down.
