Rosa hemisphaerica (R. sulphura, 'Sulphur Rose') Description... The double flowers often fail to open properly in wet weather... when the fruit sets, which is not often, it is globular and dark red. This is a fascinating rose that is depicted in several works of art by the seventeenth century Dutch Masters. It is why it is often referred to as a yellow Centifolia...

[the name] means that the flower … is shaped like half a globe. An easier name for it is R. sulphurea; and in cooler regions that is the only easy thing about it, for it is sensitive to cold and feeble unless cherished.

Rosa hemisphaerica 'Flore Pleno' (R. sulphurea Ait.) This rose has been cultivated since the early 17th century. It is similar to R. foetida 'Persiana' but less satisfactory in gardens as the flowers 'ball' in wet weather, rotting before they have opened properly. They also have a tendency to hang down. It needs a hot, dry situation in full sun to have a chance of success.
