This rose has mildewed badly along the California Central Coast. I'm hoping that as it gets older it will outgrow this mildew problem.

The Rose Annual 1939 p. 32
In the same year (1932) Bentall produced a very pretty and floriferous little wichuraiana called The Fairy. It is a dwarf grower, forming very numerous prettl little flowers in open clusters, not a great Rose in any sense of the word, but one which has become popular in my garden.

Gardeners Chronicle 1932 92: 237
The Fairy.—This variety is described as "Wichuraiana-Polyantha" and, as shown, the cut sprays made an attractive display. The plant was very dwarf and, although there were plenty of flower buds, bore only a few flowers. The very small, double flowers are of a soft shade of pink. Shown by Messrs. J. and A. Bentall.

The National Rose Society's select list of roses (1939)
The Fairy (wich. poly.), J. A Bentall, 1934.— Pale coral pink. Petalage 60. Moderate. Bedding, rockery. Perhaps best described as a miniature flowering "Lady Godiva." Height 1-ft. 6-in. Prune 34.

Roses in Colour and Cultivation (1946)

THE FAIRY (wichuraiana polyantha) has small double flowers of pale coral-pink, borne upon very dwarf and compact bushes, with exceptionally attractive deep green foliage. Bentall 1932. D. DG. NF. GPF. — — B.G. June-September. Hardy.

The health, vigor and reblooming of this rose are all undeniably positive traits. The utterly vicious thorns are only a plus in some contexts, particularly considering that it's a sprawling vine of a plant.

The Montreal Botanical Garden recommends this rose as resistant to blackspot, powdery mildew, and rust:
