Rosa hemisphaerica, also known as the sulphur rose,[3] is a rose species with pale yellow flowers native to western Asia.

[4] The wild form, known as Rosa raphinii, has single flowers with five petals.

A double-flowered form was one of the first yellow roses introduced to European gardens; John Bellenden Ker Gawler stated in 1815 that the species had been cultivated in England for nearly 200 years.

[6] The name Rosa hemisphaerica refers to the half-rounded fruit and ovaries, Latin "pomo hemisphaerico ... Germen hemisphaericum".

[7] Rosa hemisphaerica is a prickly shrub that grows to about 1.5 metres (4 ft 11 in) high with grey-green leaves of five to seven leaflets.
