[From "Reappraisal of Rosa Arvensis Biodiversity", by Pascal Heitzler, pp. 16-22]
Rosa arvensis is largely distributed throughout temperate Europe. This charming species, commonly called “field rose”, is one of the very rare sciaphilous roses. The plants grow beneath shady trees in limestone forests, where their flexible canes run on the ground or over small hedges....In the wild, R. arvensis has distinctive traits, with apparently no or little variability (Graham and Primavesi, 1993). However, a few earlier reports described some varieties that differ from the standard description, the studies done by European rose specialists and taxonomists such as J. Sabine, J. Lindley (Lindley, 1820), J.B. Charbonnel, A. Felix and Fouillade, among others. The international journal “Le monde des plantes", constituted a huge forum for specialists with sharp observations and deep debates, mainly in the 1920-1930s (Charbonnel, 1925-1927, 1933; Felix, 1936-1937; Fouillade, 1927; Felix and Fouillade,1920-1938). Most variants were described to affect subtle characters, such as leaf serration (subbiserrata), hips’ form (elipsoidea), prickle density (gallicoides) or growth (majus, a lost giant form ). Alas, many competences and the vast majority of plants have disappeared....
An experimental and conservatory garden was created in Colmar, (Alsace, France) to restore, maintain and develop R. arvensis biodiversity and to investigate the species genetically. The whole collection involves numbers of holotypes, unusual or unique natural variants, mutants and hybrids, that deviate from standard phenotypes of R. arvensis, with one or few characters. Some variants fit with earlier descriptions of now lost plants, whereas others are unrecorded in both science and horticulture, but altogether this work reconstitutes most of the intra-specific biodiversity that was recorded mainly between 1800 and 1940. Very recently, this material has been submitted for an evaluation by the scientific committee of the ‘Conservatoire des Collections Végétales Spécialisées (CCVS), the specialized French network that help to preserve botanical and horticultural biodiversity through specific patrimonial collections in France.
