Herbal books of the Middle Ages list R. majalis ,'Zimtrose', in its single and double form. R. majalis 'Plena' was cultivated in the garden for many centuries. She was one of the few roses of older times with double blooms. Double-blooming varieties of R. majalis probably occurred repeatedly, before Münchhausen gave it the name R. foecundissima (R. majalis 'Foecundissima'). The name R. majalis "Mairöschen", points to an early blooming, which begins seldom in May, often only in June. The designation "Zimtrose" seems to be derived from the brown branches, and not, as sometimes claimed, from a fragrance of cinnamon in the bloom or foliage. R. majalis 'Foecundissima' forms a dense bush of 1 to 2 m high canes and suckers below the soil, which secure its survival in the locations where she is once planted. The prickles are mostly only in pairs below the leaf stalk. The dull green and hairy foliage with five to maximum seven leaflets is of varying size. Strangely enough, the stipules roll themselves somewhat in non-blooming branches, while they are extended on blooming ones. The densely filled flat small blooms are lilac-rose coloured, darker in the centre and lighter on the edges. The petals get smaller towards the middle, the whole bloom looks somewhat frayed. R. majalis 'Foecundissima' develops no hips, contrary to the single R. majalis.

Double Cinnamon Rose. This is a double form of R. Cinnamonea , a wild rose, extending across Northern Europe and Asia to Japan. It is not, therefore, remarkable that it is one of the oldest of our garden Roses, having been grown by Gerard in his Holborn garden in 1597. He writes, 'the flowers be exceeding double, and yellow in the middle, of a pale red colour, sometimes of a carnation'. 'The flowers have little or no savour at all.' In France it has had many names, the Latin Rosa Majalis, the rose of May - being used by the earliest writers. It was also known as Rose de Paques (a late Easter) and Rose du Saint Sacrement. Like its single parent it is distinguished by its wide stipules and the thorns in pairs under each leaf. The flower stem and hip are smooth. Flowers are a pale rose pink, two inches over and very double, as Gerard said, thirty-five to forty-five small petals irregularly twisted. The origin of the name has caused some discussion, some few have detected an odour of cinnamon in the flower, most have not. The ripened shoots are of a cinnamon brown, which may, perhaps, explain the name. There is a good figure in Miss Willmott's Rosa and also in Redoute.

An old Rose that used to be in nearly every garden and is now but rarely seen is the Cinnamon Rose (R. cinnamomea), in some parts of the southern counties called the Whitsuntide Rose. The small flat flowers are pretty and have a distinct scent. It makes a neat bush of rather upright habit.
