Silene dioica 'Valley High'
4th May 2017
Variegated red campions are ten-a-penny, nature throws them up recklessly. I could probably find two or three in the garden right now. Variegated campions that are stable and perennial are another matter.
This would seem to be both, although I admit that it does go downhill unless you divide it frequently.
It arose as a mutation during the micropropagation of Silene dioica 'Jade Valley' in Oregon.
