I happen to really like astrantia in general, but many of the ruby/red/rose varieties look the same to me, and the color is usually on the dull side. They are still very valuable perennials in my garden, because not every one can be or should be a bright standout color. Lars is a bit lighter and more rosy-pink, and I do believe it's my new favorite.
