Rosa sulphurea Ait. & Lindl.
The ‘Double Yellow’ rose produces a moderately thorny shrub, eight or nine feet high with large, very full, globular and regular flowers of pure yellow.  The flowers require excellent growing conditions to open fully.  [Gore, Paul (1848, 1863, 1888, 1903), Rivers (1854, 1857, 1863), Willmot].
  
Horticultural & Botanical History
Grown in European gardens since at least the 1600s, it is believed to be of Persian origin.  It was probably first described by Parkinson in the English literature.  It was figured in the Botanical Register as Rosa sulphurea.  [BR f.46/1815].  There is also a dwarf form known as ‘Pompone Jaune’, ‘Dwarf double Yellow’ or Rosa sulphurea minor.
  
History at Camden Park

Van Huysum used the large terracotta vase, enlivened by friezes of putti for the first time. He loved bold colours namely orange, reds and yellow softened by pale peonies, in the centre and R. centifolia cascading downwards in a most natural way, opium poppies with their swirling grey foliage and striking form, with a feature of auriculas of many colours with contrasting eyes adding to the effect.....

There has been a lot of controversy about the yellow centifolia rose now called R. huysumiana, painted first by Van Huysum and then later by artists Jan Van Os and Georgius Van Os. In a letter to a friend, Van Huysum says that he had to wait for a whole year to paint this yellow centifolia as no blooms were available. It must have been extremely rare, and a poor grower, as it disappeared fifty years after its introduction. Perhaps it was a chance cross with R. foetida persiana or R. hemisphaerica. We will never know, but I would like to give Van Huysum the credit for such an important discovery. It is interesting to see that quite a few flowers painted in this period have disappeared without trace. Some were painted in one century and then nothing was heard of them for a century or so when they reappeared once again. The arum lily, crinum, strelitzia and clivia are examples of this.

La "Centfeuilles jaune"....L'appellation...s'expliquait par la forme de la fleur qui pouvait évoquer la Centfeuilles. En fait, il ne s'agissait nullement d'une Centfeuilles, mais bien d'une tout autre variété...nommée Rosa hemisphaerica Herrm., ou encore Rosa sulphurea Ait. En language courant, on l'appela également le 'Rosier jaune de soufre', la 'Jaune double', le Jaune ancien', voire la 'Rose des Turcs'....'Sulphur Rose' (en Angleterre)..

A full-petalled yellow rose came to Europe through Charles de l'Ecluse, who worked in the imperial gardens in Vienna from 1573, travelled widely seeking out new plants. At a Turkish exhibition in Vienna he noticed a finely executed paper model of a garden, and his interest quickened when he saw that it contained a replica of a yellow rose. Unlike R. foetida, which he had already discovered on his travels, this flower had many petals. If there was a rose that truly matched the model, he was determined to find it.
It took de l'Ecluse some years before he finally acquired the rose of his dreams in 1601. R. hemisphaerica proved a mixed blessing, for in cool weather the buds refused to open, and in wet conditions the sulphur yellow petals would stick together, causing the flowers to ball and rot. Blooms that did succeed in opening were too heavy for the slender stalks, and the plant's overall appearance was unsightly. Moreover it was difficult to propagate and its hardiness was suspect. Nevertheless a way was found of catering for the weakness of so sensational a novelty. The answer was to grow it under glass and give it appropriate support. This succeeded so well that that for many years it bolstered the florist trade in Italy and France. It was successfully introduced in England in 1695 after several failed attempts.
When R. hemisphaerica is viewed from the side, the flower appears to be in the shape of half a sphere, which explains the reason for its name. It is not a true species, but a garden form derived from R. hemisphaerica var. rapinii, a native of Turkey, Armenia and Iran. Other names for it are R. sulphurea and Yellow Provence Rose.
