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. [5] The scent of the flowers has been described as unpleasant. [6]

John Bellenden Ker Gawler English botanist

John Bellenden Ker, originally John Gawler was an English botanist born about 1764 in Ramridge, Andover, Hampshire and died in June 1842 in the same town. On 5 November 1804 he changed his name to Ker Bellenden, but continued to sign his name as Bellenden Ker until his death. He was an unsuccessful claimant to the Roxburghe dukedom. His son was the legal reformer Charles Henry Bellenden Ker.

Etymology

The name Rosa hemisphaerica refers to the half-rounded fruit and ovaries, Latin "pomo hemisphaerico ... Germen hemisphaericum". [7]

Description

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. The hips are orange. It blooms only in the spring. [4]

Rose hip

The rose hip or rosehip, also called rose haw and rose hep, is the accessory fruit of the rose plant. It is typically red to orange, but ranges from dark purple to black in some species. Rose hips begin to form after successful pollination of flowers in spring or early summer, and ripen in late summer through autumn.
