The specific epithet Gracilis refers to 'slender branches'.[6] Prunus gracilis grows up to 6 ft (1.8 m) tall, has five-petaled leaves, and fruits ripen June–August.[7] Its red fruits are considered poor for eating, but Native Americans dried them for consumption during winter.[8] It grows in clusters and thickets.[9] It is hermaphrodite and pollinated by insects.[3]

Range

It is natively found in various states of United States, from Alabama, Arkansas, Colorado, Kansas, Louisiana, New Mexico, Oklahoma and Texas.[3][10]

Habitat

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.[3]
