To say Rosa virginiana without indicating its Author means to enter the world of uncertainty, as exist the denominations, not all resolved, of Rosa virginiana Du Roi, Rosa virginiana Koehne, Rosa virginiana Rössig and Rosa virginiana Herrm. (of which is given as synonym Rosa lucida Ehrh.). After some Authors, Rosa Virginiana Dur. is synonym of  Rosa carolina L. and  Rosa virginiana K.Koch with Rosa virginiana Koehne is of  Rosa blanda Aiton.

By convention, instead of the homonym Rosa virginiana Herrm., the name conserved (declared legitimate) with right of priority, is Rosa virginiana Mill. and the relevant herbarium sample is located in the British Museum.

Closely related to Rosa carolinaRosa virginiana is known also with the common names of Virginia Wild Rose in English, Rosa lucida in Italian, and Rosier luisant in French.

According to the diagnostic characters, fixed by Plilip Miller in The Gardeners Dictionary (ed. 8 n. 10, 1768), is unarmed, has entire bracts (leaves of the empalement undivided)  and glabrous are the ovate leaflets with serrate margins. In other texts are reported further information, here below some of the most significant.

The upper pagina of the leaves, formed by 5-7 (-9) leaflets, in the vegetative period is of intense green colour and is shiny.

The stems are unarmed but with frequent presence of paired prickles at the nodes or at the base of the leaves; the peduncles have bracts amply elliptic-pointed; the buds have widened sepals, lanceolate, elongated, the outer ones are usually pinnatifid.

After blooming, the sepals tend to straighten up, become erect, and finally deciduous; the flowers are simple, of more or less intense pink colour (rarely white) and are carried singly or 1-6 (-15) in corymb, from which originate heaps of globular rosehips, red when ripe. The Virginia wild rose blooms from June to mid-August.

Native to the coastal regions of eastern North America, it is believed that it has been one of the first American roses known and cultivated in Europe. For ornamental purposes, variants with full flowers have been preferred; in 1768 Miller himself indicated “The double Virgin Rose” as a garden rose.

The Virgina Rose is not suitable for isolated positions because it is making suckers but, conversely, is useful for borders and crosshatchings. It is attractive because of the autumnal change of colour, for the colourations of the bark of the stems going from red-brown to violet and for the masses of rosehips. It does not disdain humid soils, provided well drained, and prefers a position in full sun and soil rich in humus.

In Europe Rosa virginiana has undergone introgressions (back crossing of a hybrid with parental groups) like in its origin territories. The group of plants formed by the hybrid (Rosa carolina L. × Rosa virginiana Mill.) and its introgressors is indicated with the common name of New England Rose and the set of plants has been identified as the nothospecies (new hybrid species) Rosa ×novae-angliae W.H.Lewis
