Prunus cerasoides Buch.-Ham. ex D. Don, known as Himalayan cherry, is an ornamental plant that collected in Cibodas Botanical Garden. Moreover, the environment might be affecting the flowering period and morphological of P. cerasoides. This study was conducted in Cibodas Botanical Garden. It was aimed to evaluate the trend of the flowering period of P. cerasoides in Cibodas Botanical Garden during 20 years (2001-2020). The observation occurred five times, i.e. in 2001, 2004, 2010, 2015, and 2020. The results showed that P. cerasoides was able to flower two times in a year, but the period were not always the same every year. Generally, the flowering times of P. cerasoides in the first period was in January-February on 2001, 2004, 2010, and 2015, but in the second period, P. cerasoides experienced different flowering periods which is August 2001, June-August 2004, August-October 2010, and July-October 2015 with very rare/little (1%-30%) to rare/moderate (31%-60%) of flowers. In 2020, there was a significant shifting of the flowering period that P. cerasoides was flowering from March to June and the second period of flowering in October. The fruit only occurred in 2010 and 2015 with very rare/little fruit intensity (1%-30%) to rare/moderate (31%-60%).
