Pure bad luck that you just posted this... I was in Meise last Thursday and could have checked. I will be there again in April. I took the name from the nameplate but these are often wrong in any botanical garden. The pic from the Meise living collection you added above suggests at least you are right.
As promised I went to Meise again and checked: you are right indeed. There were two nameplates in the group, also the correct one. The other was simply overgrown by this plant, hence the error. Very well seen and corrected!

How wonderful to visit the botanic garden so frequently. Thanks for clearing this up Ruud. I approved the proposal to move the photo. I'm so happy you caught this Lin. We now have two very different looking plants in this entry.
