We have (yet another) mystery plant in our yard. I thought it might be some kind of bergenia, but the leaves don’t seem to be right—they’re distinctly palmate, and the photos I’ve seen of bergenia leaves are distinctly not. In the spring it sends up tall stalks from its corms with sprays of lovely pinkish flowers—not a leaf in sight at that point— and then the flowers die back and eventually the leaves grow. It’s a big plant, the leaves are as big as those of the gunnera next to it (in fact, overall, the plant is bigger than the gunnera) and it stands three to four feet high.
And in the autumn, this is what the leaves do.
Overall, I don’t care what it is, as long as it keeps doing what it’s doing.
