Rosa hemisphaerica The Sulfur Rose

It's been a good year for the sulfur rose, Rosa hemisphaerica: My small plant produced twenty-four flower buds, and almost to the last one they opened well. I had to give one or two buds a nudge in the way of a light pinch, but even those opened properly. What a treat to see this ancient plant flowering freely!

The unusual weather had something to do with it.There has been plenty of rain, yet the days have mostly been sunny, dry and breezy. When the weather does not cooperate, the buds ball badly.

Rosa 'White Bath': Sergeant Cuff's rose

Sergeant Cuff is a character from The Moonstone of Wilkie Collins. And just as The Moonstone is the prototype of a whole class of mystery stories, Cuff is the prototype of Sherlock Holmes,  Hercule Poirot and all the others between and since: the sort who come with the recommendation that “when it comes to unravelling a mystery, there isn't the equal in England” as Collins put it. After Cuff is introduced in the story and we are given several dozen pages to see what he is like, a totally unexpected side of his until then seemingly strict and all-business character is revealed: Cuff is in the garden having a talk with Mr. Begbie, the gardener of Julia, Lady Verinder; as Cuff and Begbie share a bottle of Scotch whisky they argue over this:  “whether the white moss rose did, or did not, require to be budded on the dog rose to make it grow well.” 

The gardener said yes, Cuff said no.

The rose which was the topic of that discussion is shown above: this is the true white moss rose. And Cuff must have been right: my plant is not budded on dog rose but rather is on its own roots. The Moonstone was published in 1868, a time when moss roses were enjoying a huge vogue in Victorian England. By then hybridizers had started several different breeding lines of moss roses, and the true old white moss was not the only white moss making the rounds. But surely someone of Sergeant Cuff’s level of discernment would have held out for the original!

It’s difficult to write with certainty about the history of the white moss rose: it seems to have existed in the late eighteenth century; on the other hand, it may have occurred spontaneously several times back then. How can that be? It’s because the pink moss rose, of which the white (or the several whites as the case may be) is itself a sport of the pink rose known back then and to some even now as “Rosa centifolia” or "the cabbage rose". All of these presumably derive from a single seed which germinated hundreds of years ago. The plant from that seed spontaneously mutated many times over the years to produce forms with pink and/or white un-mossed flowers and ultimately pink and/or white mossed flowers.  

 At the beginning of the nineteenth century, three white mosses were making the rounds: 'Shailer’s White', 'White Bath' and 'Clifton Moss'. One point of view is that these were all the same plant. Another point of view is that at least two of them, 'Shailer’s White' and 'White Bath', are distinct. To this day, it happens that white-flowered moss roses revert to pink occasionally.

Uncertainty about its history is only part of the story; in addition to ‘White Bath’ there are other white-flowered moss roses, and more than one author in the past has tripped up on the identity of the plant they were growing. And the plants in commerce have been confused for decades.

Perhaps I should add that I think my plant is the real thing, but who knows what the rosarians of the future will think.

Whatever it is, it has the qualities for which rose lovers have praised the white moss for centuries: the intense and characteristic fragrance of the flowers and the extensive growth of the sepals with their soft, resinous moss with its own distinctive fragrance.  

When the season for once-blooming roses arrives, it’s time to disconnect the phone and the television and turn off the computer and radio. People in today’s thoroughly wired world find it hard to understand why someone would willingly withdraw from social contact during the blooming season of certain plants: but gather your rose buds while ye may, indeed: this treasure among the roses is with us for a week or two only each year, and even a stay in the refrigerator can prolong that just  so much.

Tree peony time

It's tree peony time again, and this year it comes with weather which is not too friendly to this favorite flower. On several of the days when the flowers were opening the temperature came close to 90 degrees F. Under those conditions, the flowers can be literally ephemeral. This quick passing of the blooms has caused more than one commentator to question the role of tree peonies in our gardens. I'll bet there are a lot of gardens where one grows tucked away in some corner to be appreciated in its hours of glory and then forgotten for another year.

There is a way to enjoy them for a week or two: I now cut the blooms as soon as they are fully developed and then store them in the refrigerator. The earliest of the Japanese tree peonies open about a week or even more before the yellow-flowered sorts do; it's rare to see them in bloom together in the garden. But stored blooms last well, and while they last they can be removed for an hour or two now and then for table decoration - and then returned to the refrigerator.

Several years ago I staged a big group of my refrigerated tree peony flowers: the effect was really sumptuous.  The plants did so well this year that it seemed an opportunity not to be missed to stage them again. That's what you see in the image above. You should have seen the refrigerator - it was stuffed.

The grouping seen above was put together hastily (lest the blooms fall apart) about an hour ago. I won't be surprised if those flowers are on the floor tomorrow morning.
