Prunus gracilis grows up to 1.8 metres (6 feet) tall, has five-petaled leaves, and fruits ripen June–August.[4] It grows in clusters and thickets.[5] It is hermaphroditic and pollinated by insects.[2]
It is found growing in fence rows, open woodlands, woodlands edge, forest openings, hillsides, slopes, sandy roadsides, upland thickets and waste places. It is normally found at 100–1,300 m (330–4,270 ft) above sea level.[2]
