It's fairly large and I have no idea what it is.
It has large palmate leaves on single stems all growing up from the root, and white flowers in clusters. It's about 1 m (3') tall.
I have no idea what it is; it was labelled "Glaucidium palmatum" in the botanical garden of Gothenburg, but it's completely different from that plant.
Any of you have a clue?
Update: it's Diphylleia cymosa.
