Based on long-term ground-based phenological observation data collected at 10 stations of the China Phenological Observation Network (CPON), this dataset compiles typical spring and autumn phenophase data of four representative woody plant species in China over the past six decades. The dataset contains observational records of spring phenophase (onset of leaf unfolding) and autumn phenophase (date of full leaf coloration) for four widely distributed woody plant species in China: Fraxinus chinensis, Robinia pseudoacacia, Ulmus pumila, and Syringa oblata, across 10 CPON stations (Beijing, Xi'an, Shenyang, Minqin, Harbin, Hohhot, Nanjing, Changsha, Hefei, Kunming) during the period 1963–2018, with the unit of measurement being Julian day.
