In your area you would be using mostly hardy conifers. There are some broad-leaved evergreens that will persist there but these are mostly small and low types. If Prunus laurocerasus is possible it will be a continental climate type, maybe on the market there as Russian or Schipka laurel. Anything in the heath family (Pieris, Rhododendron etc.) will need soil modification if the existing condition is alkaline clay.
