The Roses of Henry Arthur Bright

Henry Arthur Bright (1830-1884), the author of "A Year in a Lancashire Garden" and "The English Flower Garden" worked in his family shipping firm while gardening at his home in Knotty Ash near Liverpool. His books on gardening were well loved due to their brevity and literary quality. Bright took up the cudgels against carpet bedding which had reached, in mid-Victorian times, absurd proportions. He is thus, along with William Robinson, one of the first "natural gardeners". He was also one of the few to recognize the writings of Forbes Watson and is therefore part of the curious chain from John Ruskin to William Robinson.

It is therefore of interest to see what roses he endorses in his "English Flower Garden" (1881). Unsurprisingly he harks back to many old English favourites at the expense of some contemporaneous roses, which by 1881 were reaching an apoapsis of artifice. To quote Bright:

"Then come roses, and we would strongly recommend that, in addition to the newer "remontant" roses, the old roses and the old way of growing them should not be quite forgotten. Standard roses are all very well, but a rose-bush covered over with blossom is very often much better. "Madame Rothschild" is pre-eminent in beauty, but (if she will tolerate the "odorous" comparison) the old cabbage rose or moss rose has a charm of scent and of association of which their fashionable rival is entirely devoid. The old pink china or monthly rose, which flowers on from early summer to latest autumn, deserves a bed to itself. It should be trained and pegged down, as is so constantly done in Belgium and Holland, and the blue lobelia should be planted in between. A bed of yellow briar rose is still more beautiful, but it lasts for weeks only instead of months. Other beautiful old summer roses are the maiden's blush, the Portland rose, the rose unique, and the rose Celeste. But no rose, taking all the good qualities of a rose together, its hardiness, free blooming, beauty, and scent, will surpass the Gloire de Dijon, though the golden cups of Marshal Niel may be richer in colour, and the fragrance of La France recalls, as no other rose does, the luscious fragrance of Oriental otto of roses".

These selections, of course, mirror the taste of Gertrude Jekyll as detailed in her book, the eponymous inspiration for this blog. We begin to see the threads gathering into her yarn.

The "odorous comparison" is a pointed dig, as Madame Rothschild has no scent and what is a rose without scent? Unique is the white form of the cabbage rose, Rosa centifolia, an old rose and like the pink cabbage rose guaranteed to take any eminent Victorian back to their childhood. Celeste, like Maiden's Blush is an old alba, one of the "cottage garden roses". Gloire de Dijon, an advanced noisette, was universally acclaimed the finest climbing rose of the nineteenth century. Miss Jekyll writes of it: "The most free-flowering of all climbing Roses, and for general usefulness has no equal".

Is the single rose more beautiful that the double? Reflections on the work of Forbes Watson (1840-1869)

Poor Forbes Watson! During his final illness and before dying in agony aged 29 he comforted himself by writing about flowers and gardens. Then he gave the manuscript to a friend for posthumous publication. This slight work on aesthetics ("Flowers and Gardens") would be completely forgotten had it not formed a link in the chain between John Ruskin and William Robinson and inspired the "natural gardeners" who later turned Victorian formal gardening on its head. Drawing on Ruskin's principles of art and aesthetics, he was the first to rebel against carpet bedding and Victorian formalism.

There is a saying "beauty is in the eye of the beholder". Forbes Watson believed the opposite. For him beauty was an objective, almost tangible quality, that God had placed in all flowers, like mass and density, for the observer to find, like some divine Easter egg hunt. Being devoutly religious the door to beauty through function, that Darwin had opened, was closed to him. He considered not the aesthetics of the bee. Whereas Darwin's beauty opened the human spirit to gigantic and majestic vistas, Forbes Watson's beauty came from sentimentality and the supernatural.

Canon Ellacombe described him thus:
"a man of unblemished character and pure life; an intense lover of truth, wherever he could find it, and a hater of shams and falsehoods of every sort; a warm friend, especially to the poor, to whom he was most liberal, even with limited means, and a labourer among them, teaching the boys, and sparing no labour to help them in leading good lives; a deeply religious man, to whom his religion was part of his life, and a very strong Noncomformist"

Roses were a particular problem to him, because he loved the double roses that man had created, the "deep warm bosom" of the cabbage rose and the moss, but were these roses of Man's creation better that the wild briars of God's? Heaven forbid! Imagining a stubborn interlocutor, he wrote:

'"But study the single rose as I may", you perhaps tell me, "I cannot like it much after the double one. I think it wants body, it seems loose and weak, and I really care little for it…these little points you mention, the stamens and the pistils, never enter my head for a moment; and I do not feel the want of them, they are wholly forgotten in that luxuriant fullness of beauty…"

The one thing really proved is this, that your taste is most seriously injured….though in turning to the Garden Rose I cannot feel it faulty any more than you do, I soon find that I miss something there; that is, I should soon be wearied if I had none but such Roses as these, and was absolutely debarred from the complete wild ones. And do you not see the reason of this, viz., that the beauties of the cultivated Rose are more especially of that sensuous striking kind which can hardly be overlooked, and are apt to veil in their blaze the simpler and less obtrusive, though more deeply satisfying, charms of the Wild Rose?'

Amen to that?

The decaploid Shangri-La Rose, Rosa praelucens

Up until recently the highest chromosome number known in roses was octoploid (2n=8x=56). C.C. Hurst had hypothesised that all roses derive from a theoretical Arctic decaploid (2n=10x=70), from which he theorised all other roses descend by progressive loss of chromosome complements. This decaploid was never found.

However, it is now established that a rose found on the Zhongdian Plateau of China is decaploid. This high plateau (over 3000m elevation) in Yunnan is the gateway to the Tibetan plateau. It has a stunningly rich flora, although the natural ecosystems have been severely damaged by yak and cattle overgrazing.

On this plateau grows the decaploid Rosa praelucens, the Shangri-La Rose, an elegant rose with large solitary pink to red flowers and leaves with small hairy leaflets.

Is this the ancestral decaploid of Hurst? No, Hursts theory is still wrong. Instead of having chromosomes of all five of Hurst's fundamental rose types (his "septets") it appears to be a specialised Chinese rose, possibly sharing a hybrid origin with Rosa roxburghii, the Chestnut Rose, which it slightly resembles. The Flora of China classifies both the Chestnut Rose and the Shangri-La Rose in section Microphyllae as they both have a depressed-globose hypanthium with achenes inserted at projecting torus at the base.
