Rosa bishopii

About

Rosa × bishopii is a hybrid species of rose in the family Rosaceae. It belongs to the genus Rosa and grows as a deciduous shrub in temperate environments. The hybrid is the result of a cross between Rosa agrestis and Rosa micrantha, giving it the formula R. agrestis × R. micrantha. It is native to Scotland and England, where it is typically found in hedgerows, scrubland, and along woodland edges. The name was first published in Revision of British Roses on page 99 in 1931. Like many wild roses, it is well adapted to the temperate climate of its native range.
