Resista®-elms

Resista®-elms

A typical Dutch tree

There are few tree species that have been able to leave a bigger mark on the Dutch landscape than the elm. It is therefore not for nothing that the tree species is mentioned in Hendrik Marsman's famous poem ‘Remembrance of Holland’. The history of the elm in the Netherlands has been eventful, with high peaks and deep valleys caused by attacks by the elm spider beetle. Since the introduction of the resista® line, the elm has returned to the landscape and once again become a picture-perfect tree. In the Netherlands, Boomkwekerij Ebben and Noordplant nurseries are licence holders for resista® elms. Ebben is also the licensee for the exclusive supply of elms from the resista® line for Luxembourg and Ireland.

Resista® elms have been carefully bred for reliability and high resistance, following rigorous selection processes of more than ten years of private trials and three years of official testing of numerous crosses. Selected specifically for the European market, these varieties are available exclusively through authorised partner nurseries. With their rapid growth, making them easy to establish and settle down quickly and adapt to extreme temperatures, these trees also serve as a valuable habitat for insects, especially the endangered elm butterfly.

We offer four different selections: Ulmus ‘Fiorente’®, Ulmus ‘Rebella’®, Ulmus ‘Rebona’® and Ulmus ‘New Horizon’®. The latter two in particular are completely immune to Dutch elm disease and tolerate drought, salt and short periods of waterlogging, making them ideal for coastal environments.

Elms in the Netherlands

Elms in the Netherlands

Elms have represented a fixture in the Dutch natural landscape for centuries. Ulmus glabra (Wych Elm), Ulmus laevis (European white elm) and Ulmus minor (Smooth-leaved Elm) have played a prominent role in Dutch dendrological history; from the Middle Ages onwards, the tree species was widely planted along roads and in cities because of their fast growth, good-quality wood and aesthetic value. Partly due to these properties, the elm gained a prominent place in Golden Age Amsterdam, where they graced the characteristic canals. The many visitors to the metropolis also noticed this, resulting in the trees being described several times and frequently exported from the seventeenth century onwards. The Ulmus x hollandica (Dutch elm) had definitely knocked the Tilia x europaea (Dutch lime) off its throne in the capital.

Dutch elm disease

The popularity of the species in the Middle Ages meant that the Dutch landscape was full of elm varieties. The fact that the elm thrives on different types of soil, is resistant to drought and temporary flooding and insensitive to salty sea winds made it the perfect tree for our country. Yet things turned out not to be all roses: from the early 20th century, the species suffered a series of outbreaks of Dutch elm disease. This disease, caused by fungi spread by the elm spider beetle, ensured that little remained of the elm as a typical Dutch tree. After outbreaks in 1918, 1930, 1984-1985 and 2000, the Dutch elm population was decimated.

Research resistance

Dutch elm disease was first isolated and identified by Dutch phytopathologists Bea Schwarz and Christine Buisman in 1921, leading to the disease becoming known internationally as Dutch Elm Disease. Research into resistant elm species started in several places worldwide, including at the Dutch forestry research station De Dorschkamp by Hans Heijbroek. The largest study was conducted at the University of Wisconsin led by Professor Eugene Smalley, where a wide selection of international elms were infected to study the disease course. Dutch native elms were found to be very susceptible. However, some Asian species proved to be resistant to the disease and were used to develop some resistant varieties that manage to isolate the fungus when infected at the twig level.

Return to the landscape

In the Netherlands, tree nursery Noordplant in Glimmen, Groningen, is the elm specialist. Our resista® elms are grown on their own roots to ensure not only resistance to the elm sapling beetle but also no risk of (delayed) incompatibility. Ebben's acquisition of Noordplant in 2023 gives Ebben access to very extensive knowledge of and experience in the cultivation of resistant elms. German company Eisele GmbH & Co acquired the propagation rights of resista® elms in Europe in the 1990s. The trees are each labelled with the resista® trademark and a chip on which the master licensee can read out information about the respective tree.

Licensee

In the Netherlands, Noordplant and Ebben are licensees of resista® elms. In Ireland, Ebben is a licensee. The licence covers the following selections:

Ulmus ‘New Horizon’®
Ulmus ‘Rebona’®
Ulmus ‘Fiorente'®
Ulmus ‘Rebella’®
