Please identify this foreign plant

hallo,

please see picture - i have no idea what this is - it grows to about 5 feet on one stalk and produces these seeds. when they burst they seem to have lots of seeds that are spread with a fluffy 'tail'.
Seen in a garden in Hungary, on the shores of Lake Balaton. Must be a hardy thing as winters can get to -10 celsius.
I have an other weird and lovely thing for ID in my next post.
thanks, karaman

 

Only seen it in flower...so just a suggestion...Asclepias syriaca.
