Rubus ulmifolius is a species of wild blackberry known by the English common names elmleaf blackberry and thornless blackberry and the Spanish common name zarzamora. Native to Europe and North Africa, it has become naturalized in the Americas and Australasia.
Description
[edit]Rubus ulmifolius is a brambly shrub sometimes as much as 5 meters (almost 17 feet) tall, sometimes with spines. The leaves are palmately compound with 3 or 5 leaflets, the leaflets green on the upper surface but white on the underside because of a dense layer of woolly hairs.
The flowers are usually pink, sometimes white. The fruit is a compound drupe, dark purple, almost black.[2]
Rubus ulmifolius is unique among subgenus Rubus in displaying normal sexual reproduction; all other species are facultative apomicts.[3]

The leaves resemble those of elms.
Subspecies
[edit]Rubus sanctus is often considered to be a subspecies of R. ulmifolius.
Distribution and habitat
[edit]Rubus ulmifolius is found in its native range across Western Europe, from the Netherlands south to Spain and Portugal, in Britain and Ireland, as well as northwest Africa. It is naturalised in the west in the Americas (as well as southern South America) and Australasia.[2][4]
In Britain and Ireland it is a plant of hedges and woodland edges on calcareous soils.[3]
