 The tree readily suckers from the roots, notably on chalk.Tests in France by INRA found the tree to be 'highly resistant' to Dutch elm disease, exhibiting the lowest wilting percentage of all the clones trialled, making it comparable with 'Sapporo Autumn Gold'
However, the presence of "U. wallichiana" in the ancestry of poses the risk of susceptibility to elm yellows (phloem necrosis), which seriously damaged its Dutch stablemate 'Lobel' used as a control in the Italian elm breeding programme.The clone has also proven susceptible to Coral spot fungus "Nectria cinnabarina" in the Netherlands.
