We have no true single Damask Rose in the garden, the nearest approach to a simple form being Mrs O. G. Orpen, a rose that was bred in England at the beginning of this century, and one which we purchased in New Zealand many years ago. The large rosy-pink flat Blooms have five deeply notched and veined petals. As well as These, there are a number of Shell-like petaloids which surround a glorious ring of rich fat yellow Stamens which embellish the centre of the rose. This Damask flowers late in the season, at the same time as ist neighbour, the lovely Celsiana. The blooms of York and lancaster, which grows nearby, are well past their best when These fine shrub roses come into flower. It is rather pleasant to have the season of the Damask Roses Extended in this manner, as it means that we can gather Blooms of one variety or another for up to three months. Miss Rose Kingsley, in her book Roses and Rose Growing, has included an excellent coloured Illustration of Mrs. G. O. Orpen, which gives a good idea of this modern Damask.

Single Roses.
In our Nurseries there are no more attractive objects than the Irish single varieties, and they are so marvellously free flowering that it is impossible to say too much in their praise. During the entire growing season they are virtually always in bloom, and their lasting properties are most surprising.
Mrs. O. G. Orpen (Damask)... O.G. Orpen, 1906, very vigorous. Bright rosy pink, with golden anthers, Gold Medal, N.R.S.
