Translation:
"Dornenlose Kreiselrose", Rosa x suionum, Minette.
Hybrid Francofurtana, Turbinata, before 1820, 120 cm and more, good fragrance.
Summer-blooming.
The origin of this rose is unclear. Likewise its classification. Sometimes it is stated »before 1815«. The oldest source I know is 1819.
The valid name should actually be ‘Minette’, at least this appears almost continuously in the sources. The German name is popular - at least in the German-speaking countries.
The rose is without thorns, is clear, but it has pointed, grayish prickles ... In our latitudes always hardy, blooms in summer, doesn't like rain, the blooms then ball badly. But tolerates semi-shade well.
Is called Alba, even Centifolia. Do not see on the rose where these assignments come from. For me, simply a wild rose hybrid (unknown parents and origin).
‘Francofurtana’ itself is also a wild rose hybrid with more than a dozen synonyms (“Tapetenrose”, Rosa inermis (turbinata), Rosa x francofurtana ‘Kreiselrose’, Rose without prickles); Rosa x francofurtana is probably a cross between Rosa majalis and Rosa gallica.
‘Kreiselrose’ refers to the peculiar goblet shape, rounded, top-shaped and with delicate bristles or hairs; in Rosa x francofurtana the upper area is smooth and more clearly offset than can be seen here with this variety. The whole calyx seems to me more like a "drinking cup" than a spinning top. However, seen as a whole with the closed bud showing no color, the link to this toy may be closer. Because then everything in the crown petals comes together nicely - and it may turn around mentally ...
Photo /. shows well the peculiar overlapping of the leaflets of this rose, continuously at the tip actually with all leaves.
