Description

Black jetbed is a deciduous ornamental shrub in the Rosaceae (rose) family that was introduced to the United States from eastern Asia in 1866. The name comes from the Greek word rhodon which means rose and typos meaning type, the species name scandens means to climb.  The form is loosely multi-branched and mounded to somewhat arching but it can appear unkept and ragged in the landscape and can quickly reach a height of up to 6 feet tall.  It grows from full sun to partial shade in a wide variety of soil types including clay as long as they are well-drained.  

Four petaled showy white flowers appear in late spring to early summer and are followed by shiny black fruits that appear in groups of four in the fall and last throughout the winter months.  

It is drought and pollution tolerant, adaptable to urban and shade conditions, and is very cold hardy.   Black jetbead escapes cultivation and invades forests and forms a thick shrub layer causing native plants to be displaced.   Due to its rapid growth and weedy tendencies it should not be planted in the landscape, consider native alternatives listed in the left column.

Insects, Diseases, and Other Plant Problems:  No serious insect or disease problems.  This plant is an aggressive grower and is invasive in some areas of the eastern United States.
