Description
Prunus buergeriana individuals usually reach a height of. The small flowers are borne on a raceme. The fruit ripen from green through red to black.
Considered an unlovely tree in Japan, the dog cherry is used as a simile in Japanese haiku for unflattering comparisons with dogs; in these the paltry raceme resembles the tail of a whipped cur, or the spotted bark the markings of a starving mongrel.
