I have been reading Crépin's discussion of Rosa wichuraiana and R. luciae. He makes it clear that R. wichuraiana is a ground-hugging, sprawling species that doesn't do UP. To the contrary, R. luciae and R. multiflora start as bushes or shrubs, and apparently need some external stimulus to trigger the climbing habit.

I have observed this phenomenon in R. multiflora, naturalized in Tennessee, as well as in the native R. setigera. The plants remain short and bushy when growing in the open, but "take flight" (so to speak) when there is a tree nearby.

I grow R. wichuraiana too. And despite nearby oaks and hazelnuts, it stays over the years (as You described) "ground-hugging" and doesn't reach for the stars.

That's what I would expect. It does horizontal, but not vertical. I had one, years ago, that insinuated itself through my lawn. When I finally discovered it, I had a heck of a time getting it out.

If you had R. luciae, according to Crépin, it would remain a bush/shrub until it bumped into a fence or tree that would give it a "leg up".

I planned it as a thick thicket, to ward of astray strangers from our garden. It can endure a lotta shade.

I saw R. wichuraiana var. poteriifolia growing at the San Jose Heritage garden. Now, THAT would give stray visitors second thoughts ... and third thoughts. Dense, twiggy and mean looking.

I had a small specimen of it in a pot. The darned thing somehow managed to snag me whenever I got near it. I thought I was being careful, but it got to me anyway. Finally, I cut it back to stumps. It promptly opened a few blooms - in December - just to taunt me.

It is no wonder that Wichuraiana hybrids are so durable and carefree. I saw them (double pink and double red) in numerous places in Tennessee, growing beside the roads, or hanging over cliffs. No care required.

I wonder whether the Wichurana hybrids of Barbier are not all Luciae-Hybrids

We are getting into the Lumper/Splitter dispute. Crépin consulted with Franchet, and they agreed that Crépin's Rosa wichuraiana was a form of R. luciae. However, after much further study of other specimens, Crépin concluded that Multiflora, Luciae and Wichuraiana are distinct, despite the apparent overlap. Therefore, we get to choose whether we call a trailing specimen with very glossy leaves Rosa luciae Franch. & Rochebr. or R. wichuraiana Crép.

I am familiar with only three of Barbier's hybrids. 'François Foucard' (my favorite), 'Paul Noël' and 'François Juranville'. The first two were growing in full sun, and sent out wiry canes that sprawled along the ground like R. wichuraiana. I didn't pay as much attention to 'François Juranville' because it was in a less favorable setting.

I'm still trying to figure out the heredity of the climbing/creeping habit. Environmental conditions may be involved in triggering the change from shrub to climber. I am trying to learn whether two species that rely on different conditions might yield hybrids that don't need either. And so they would start out as "climbers" that have no choice but to sprawl.

Does anyone know who the Edmond Proust was after whom the rose was named? A cursory search on Internet didn't turn up anything.

Why did you put your question under R. wichuraiana? I'll respond further in 'Edmond Proust'
Reply #2 of 2 posted 9 JAN 16 by MelissaPej
Oops. I wasn't paying attention, that's why. I had been looking at parentage of 'Edmond Proust' earlier and forgot I wasn't still there.

Curtis's Botanical Magazine v. 121 t. 7421 (1895) gives R. maximovicziana Regel as a synonym for R. wichuraiana/luciae.

Garden and Forest 4: 570 (1891)
THE handsome Rose which is figured on page 569 was sent to the Arboretum by Mr. Louis Spath, of Berlin, in 1888 as Rosa bracteata, but when it flowered two years later it was found to be the Rosa Wichuraiana of Crepin,* a native of Japan, and previously confounded with Rosa Luciae of that country, and still earlier with Rosa sempervirens.

Rosa Wichuraiana is remarkable in producing slender prostrate stems, which grow ten to fifteen feet long in a single season, and cover the ground as with a dense mat; they are free of prickles and produce short, stout, straight or slightly recurved spines, and in moist ground develop rootlets freely. The leaves are three to nine-foliolate, with obovate or nearly orbicular blunt leaflets, which are sharply and coarsely serrate, glabrous, very dark green and lustrous, and from a third to two-thirds of an inch long. The stipules are adnate, usually conspicuously toothed, and vary from a third to half an inch in length. The flowers are produced here in great profusion from about the 8th to the end of the month of July, and during the remainder of the season appear irregularly and less abundantly; they are pure white, an inch and a half to two inches across, very fragrant, and are borne in short, broad, pyramidal, terminal, few or many-flowered clusters. The primary bracts are lanceolate, foliaceous, dentate and persistent. The pedicels are stout, an inch long, slightly glandular-hispid, and furnished with lanceolate, denticulate, rather persistent, bractlets. The flower-buds are a third of an inch long, ovoid and abruptly contracted into short points. The sepals are oval, contracted at the apex into rather rigid points, coated with pale pubescence on the inner surface and reflexed at maturity. The petals are broadly obovate, slightly emarginate at the apex, and sometimes rather remotely dentate toward the base. The stamens are bright golden-yellow and very conspicuous; and the column of styles is elongated, rather thick, and pubescent. The fruit is oval or obovate, dull red, and from a third to half an inch long. It matures here late in the season, producing good seed every year.

Rosa Wichuraiana has been used very largely during the last two years by the Park Department of the city of Boston, especially in Franklin Park, for covering rocky slopes, embankments and such spots as it was desirable to clothe quickly with verdure. It appears to be admirably suited for such purposes, and as it grows more rapidly than almost any other vine which has been tried in similar situations, soon making a dense mat over the ground, it seems destined to become a popular plant. Its remarkable habit, its hardiness, the brilliancy of its lustrous foliage, and the beauty of its flowers, which appear when most shrubs are out of bloom, certainly recommend it to the attention of the lovers of hardy plants.

Detailed descriptions like this are so good to have. Thank you for your time in sharing, CybeRose.
"free of prickles, but has spines" has me puzzled though.
Reply #2 of 5 posted 16 MAR 12 by CybeRose
Maybe the author meant that the stems were free of bristles ... that's my best guess.
Reply #3 of 5 posted 16 MAR 12 by Patricia Routley
Yes. Good guess. Thank you Karl

But the leaves have mean hooked little prickles!
