That's a pretty one
I grow Geranium 'Philippe Vapelle' which has that same foliage but darker flowers. I love the foliage of these but with Philippe Vapelle the flowers unfortunately don't last all that long. Is that the same way with White Knight?
Still, foliage can be nice. This is a shot of Acorus planted with Geranium 'Philippe Vapelle'. Nothing but foliage
