Parks' Yellow China (China) [] Also known as Rosa Indica var. ochroleuca Lindley, this variety was imported from China by John Damper Parks in 1824. 'Knight's Yellow China', a self-seedling of the 'Blush Tea-scented' rose, was commonly mistaken for Parks' rose. Parks' rose was not a Tea rose, according to the standards of the day. Its leaves were "not shining", like the early Tea roses, and was "entirely different from any other".

John Lindley
XXXV. Rosa Indica var. ochroleuca.
This plant was brought for the Society from China, in 1824, by Mr. PARKS, as one of the interesting yellow China Roses, which have long been known to collectors by the drawings of the Chinese; but upon flowering it proved to be neither R. pseud-indica, nor R. xanthina, but a variety of Rosa indica, with pale sulphur-coloured flowers.

It is a plant with a less vigorous habit than the common R. indica, resembling in that respect, R. i. odoratissima. The branches when young are covered with many small glands; leaves smooth, of a thin texture, and not shining, leaflets rather convex, and by no means veiny; leaf-stalks covered with glands, among which a few little hooked prickles are intermixed. The flower-stalk is glandular, tube of the calyx campanulate, and nearly smooth, sepals reflexed, quite simple, villous, and glandular at the edge. The flowers are very large, solitary, pale sulphur colour, quite double, very fragrant, not expanding much more than R. sulphurea; but under the influence of much heat, opening fully, when they measure four inches across. This is one of the finest varieties of China Roses known in the gardens, and so entirely different from any other, that it may be considered an important addition to our collections. It appears to be hardy, but thrives in a conservatory, where it expands its flowers better than in the open air.


CybeRose note: The illustration above shows the convex leaflets, hooked prickles on the stalks, simple sepals, campanulate calyx tube, and solitary flowers. These features are different from those described by Pirolle in Redouté, below, with calyx tube ovoid, compressed; sepals, one simple, the others slightly pinnuled around the edges, but all terminated in almost linear leaflets; terminal flowers in umbels often three or more. This plant is almost certainly Knight's Yellow China, Rosa odorata var. flavascens Swt.

cv. 'Sulphurea'.—A seedling of 'Odorata' ('Hume's Blush'), figured by Andrews in Roses, t. 86 (1826); raised by Knight, the Chelsea nurseryman, it had pale yellow, semi-double flowers. Andrews called this rose R. indica sulphurea, and it is probable that the rose portrayed in the third edition of Redouté, Les Roses (1828-30), under the same name is the Knight seedling and not 'Parks' Yellow', as usually supposed.
