The RESISTA® elm: tree of the future

The RESISTA® elm is resistant to elm disease and therefore ideal for roadsides and parks. We are one of the few specialist companies in Europe with permission to grow and market RESISTA® elms. We offer 4 disease-resistant varieties:

Fiorente New Horizon | Regal | Rebona

Why Choose RESISTA®?

  1. RESISTA® elms are tried and tested.

    Their resistance to Dutch elm disease is regularly checked by means of infection tests. Cultivation from the trees’ own roots prevents any incompatibility with rootstock.

  2. RESISTA® elms Are undemanding.

    These elms are able to deal with even extreme conditions. They flourish in soil that is poor in nutrients and humus, light and dry, as well as in heavy, dense and poorly aerated soils and even sealed areas and soil on cliffs, rocks and rubble. RESISTA® elms are stable, hardy and wind and frost resistant. They also tolerate damp locations and intermittent flooding.

  3. RESISTA® elms Are Low Maintenance.

    Corrections in the crown area are hardly ever necessary. The leaves decompose very quickly, the fruit is small and no honeydew is produced. Minor damage is quickly covered over.

  4. RESISTA® elms Offer reliable Quality.

    All propagation is performed in Darmstadt, Germany. All varieties with the RESISTA® trademark have been tested and recorded in the EU catalogue of varieties. The plant variety rights are held by Eisele GmbH & Co KG of Darmstadt. All RESISTA® elms have a special variety label and are delivered with an implanted microchip. An authenticity certificate is attached to each delivery.
