Ruud, that is always so sad when we lose such treasures, and many of the public gardens are.
I went back and checked to other photos, actually all of them are correct. I know that is hard to believe because of such a wide variance in coloring. For L and OL the color swings are huge, depending on season and growing conditions. I actrually had mine verified by the breeder. He visits my garden quite often. My favorite time for color is in the spring and early summer for this cultivar. Unfortunately it is a terrible winter rotter. I kept if for years and it always ended up healing and recovering enough to make a new colony. I finally eliminated it from my collection.
