In 2010 I picked up a small plant called gracillima. I had it in a horrible spot and almost lost it. It finally flowered last season. A spidery looking flower shaped like laevigata but darker. I liked the flower a lot and decided to make a trough full of it. I ordered a few more from a different source (my mistake but I couldn't get them from my first source). The new ones flowered this season with a completely different and ordinary flower. In researching the topic on dark striped hosta flowers I came across one in the Hosta Library called "gracillima Saizaki Hime Iwa" http://www.hostalibrary.org/g/gracillimasaizaki.html that matches the first gracillima I have.
Here is the new one I got in this season that is the "normal" gracillima.
And here is the "unusual" one that got me interested in this one last season - which I think is gracillima Saizaki Hime Iwa.
