PILLAR ROSES
Donald Beaton

...we have Splendens, Pierre de St. Cyr, and Madame Desprez to add to our list of rose-coloured from the Bourbons. Some people object to Splendens and Madame Desprez because their flowers come too near the colour of the old large China, so common against cottage doors all over the country, but then, there are no more constant bloomers in the catalogue, except Gloire de Rosamene, and the true Splendens is really more like the latter than any other rose, and though not very double, it is always in bloom, and attractive. There is a very common-looking rose called Splendens, in some collections, and I once had it from Bath, but I cut his head off the moment I saw it. I believe the true Splendens is now on sale in all the nurseries.
