Black walnut, from North America to Texel island?

On 30 June 2015, Ms Sytske Dijksen of Ecomare museum found a nut on the beach of De Hors, in the south of Texel island in the Netherlands.

The nut turned out to be a eastern black walnut. Probably, the Gulf Stream had brought it all the way from Florida or elsewhere in eastern North America to Texel. These nuts drift well.

There are a few eastern black walnut trees in parks in Europe, but the nuts on beaches there probably have all made long trans-Atlantic journeys.

In 1995, for the first time an eastern black walnut was found on a Dutch beach; also on Texel. Since then, it was found a few scores of times in the Netherlands. They have been found in France and England as well.
