This study was undertaken to examine the pollen morphology of some of the exotic shrubs and trees found in the parks and the gardens of Edirne. In the present work five plant species were studied in this respect, namely: Aesculus hippocastanum, Buddleia davidii, Crataegus oxycantha, Elaeagnus angustifolia and Philadelphus coronarius. Pollen samples belonging to these species were examined with light photomicroscope as regards some morphological features, principally: pollen shape; size; aperture characters; sculpture and structure of the exine. Pollen grains of examined species were spheroidal in shape and most often tricolporate type. Exine layer of examined grains exhibited eutectate structure except the exine of the Philadelphuscoronarius whichexhibited semitectate structure. Exine ornemantation (Sculpture) of pollen grains had determined as striate in Aesculus hippocastanum , Rugulate- Perforate in Buddleia davidii, Striate - Perforate in Crataegus oxycantha, Psilate-verrucate in Elaeagnus angustifolia and reticulate in Philadelphus coronarius
