The national register counts these three trees as one.
Dutch Elm
Ulmus x hollandica
Dutch elm disease is named for the country that first identified it, which makes every mapped tree of this hybrid a small act of defiance. We map 7 of them, in 5 cities.
Amsterdam's Oudemanhuispoort elm has turned a brick-walled courtyard into an advantage, reaching 35 metres because the only direction open to it was up, and a second Amsterdam elm is the last of roughly thirty planted outside Centraal station in 1889, the rest lost to the epidemic decades ago. The Hague's Malieveld elm dates to the 1830s and has now outlived two separate waves of the disease, the second and worse one arriving in the 1970s. In Portland, the Rockey elm survived a 1963 demolition order only because an architect parked his car where the removal crew needed to stand. Each of these is a tree the fungus could have taken and did not.
Alkmaar
Amsterdam
The tallest tree in Amsterdam stands in a courtyard barely wider than it is tall.
Around thirty elms were planted in front of Amsterdam Centraal after the station opened in 1889.
Leiden
Most of the street elms in the Netherlands are gone, killed since the 1970s by the disease that carries the country's name.
Hoorn
Dutch elm disease is named after the Dutch scientists who identified the fungus in the 1920s, not after the country's elms, but it took those too.
Twenty Dutch elms went into Park Baadland between 1900 and 1910, and two are left standing.
Portland
A Portland architect once parked his car against this elm so the removal crew could not reach it.
