The frontage of the Castlewood condominium was eighty metres long, standing back from the other buildings along the street, and screened with a discreet row of tall caucasian elms.

Zelkova carpinifolia (Zelkova or Caucasian Zelkova) is a species of Zelkova, native to the Caucasus, Kaçkar, and Alborz mountains in the extreme southeast of Europe and southwest Asia.

Of particular interest here are Taxus baccata, Hedera helix, Juniperus sabina, Zelkova carpinifolia, Rhododendron caucasicum.

In 1896, George Nicholson raised it to species rank as Zelkova verschaffeltii, while its much closer similarity to Zelkova carpinifolia led Augustine Henry to suggest it might be a hybrid between Zelkova carpinifolia and Zelkova abelicea.
