Lychnis yunnanensis: I bought this at the Beltsville Garden Club Sale last year

I know nothing about it except that it is a Chinese, go figure, Lychnis that has limited availability through a few specialized nurseries. The actual color is better than I am showing though I'm not sure in what way. It looks a bit "too" colorful in the picture, but is pleasant in the garden! Reportedly it's a reliable, long-lived perennial for the front of the border. Next year I'll know more!
