Prunus padus is commonly called the Bird Cherry (although that is sometimes used for other species in this genus), and is also known as the Mayday Tree, hagberry or hackberry too. It is a small deciduous tree usually reaching no more than 20 meters in height. It is native to northern Europe and northern Asia including Japan.
The flowers are hermaphroditic and pollinated by bees and flies attracted to the nectar by the almond-scented blossom. The fruit are small, red-black and quite astringent, but this doesn’t bother birds that do not find bitterness unpleasant.
