The rose at Hildesheim is a
Rosa canina, also called a dog rose. According to legend, it dates back to the establishment of the diocese of Hildesheim, around 815. The buildings were constructed around the area in which the rose was growing. Dog roses, the
Caninae section of the genus
Rosa, have around 20–30 species and subspecies, which appear in a variety of shapes and occur mostly in northern and central Europe. The rose that grows on the Saint Mary Cathedral belongs to the
Rosa canina and it shows the specific features of a
canina, being a
deciduous shrub normally ranging in height from ; however occasionally it can climb if given support. The stems are covered with small, sharp, hooked spines to assist it in climbing. The leaves have between five and seven leaflets. The flowers are usually pale pink, fragrant, in diameter with five petals, and develop into oval red-orange coloured
hips. The fruit is noted for its high
vitamin C level and is used to make tea and marmalade. The rose hips are used in
traditional folk medicine as a remedy for inflammatory-related diseases. In traditional Austrian folk medicine the rose hips have been used to make a tea for treatment of viral infections and disorders of the kidneys and urinary tract. The mature rose is also attractive to wildlife, various insects and serves as a shelter for nesting birds. The birds eat the hips in the winter. The rose blossoms usually survive for around a fortnight and appear toward the end of May but this can vary slightly according to weather conditions. The flowers have a pale, very light pink colour with a slight white colouring in the middle and they are of a medium size. The flowers have a rather light fragrance. The five petals of the flowers are weakly undulated. The leaves are shiny dark-green on the upper side and hairless on the underside. The rose hips are oval and quite elongated and of a bright medium reddish colouring. The thorns are of medium density and size. In 1945 during the
Second World war Allied bombs devastated the cathedral, but the rosebush survived. The parts of the plant above the ground were damaged but the roots survived beneath the ruins, and the hardy rose regrew and blossomed again. Not all roses are so durable; the longest living rose bushes are mostly categorized as wild roses.
Garden roses and other rose
cultivars may have a much shorter lifespan of only a couple of hundred years. The
tea rose has the shortest lifespan: it might not survive more than thirty to fifty years. ==History of the settings==
