Tufted Loosestrife, Lysimachia thyrsiflora.
Helsinki mystery flower, can you identify this?
Photographed at the gardens at the TarvaspÃ¤Ã¤ CafÃ© at the Gallen-Kallela Museum
near Tarvon Salmi in Helsinki, Finland.
This isn't the best picture I've ever taken, but I hope it's good enough that you can identify the plant.
Again I'm not familiar with Finnish plants, but in England I would call this Tufted Loosestrife, Lysimachia thrysiflora. A rare plant here which is rarely seen in flower.
thanks adrian, you're correct!
