Rosa longicuspis, commonly known as the Wild Rose, is native to eastern Himalayas. In its native habit it grows in thickets.

The etymological root of the binomial name Rosa is from the ancient Latin term for the rose. Longicuspis is derived from the Latin longus meaning ‘long’ and cuspis meaning ‘point’.

The landscape architect may find Rosa longicuspis useful as an informal barrier plant. It may also be grown up structures and can be used to screen unsightly objects.
