Does R. Wichuraiana produce suckers? I would like to use it to cover a steep slope about 25'x15'. How many years will this rose take to fill it up, or do I need more roses, said 8?

I'm in Seattle, zone 8b. Noon to sunset sun.

At my place, it doesn't sucker (isn't own root), but roots easily, where ever the cane-tops touch the earth. Strikes easily too from cuttings. Doesn't really climb up, but spreads over the ground and the bank.

You would need to mulch the ground very thickly so you don't have to weed among the prickles. It is more than possible that you would regret having planted it.

Mulch is always good, but over here, it doesn't behave like a beast, like down-under. Climate? Own root? Soil? Fertilizer?

Climate I suppose. See www.helpmefind.com/rose/l.php?l=21.79423 in an old cemetery, where it wouldn't have had any attention for years, apart from clearing the paths. I don't think any rose is suitable as a ground-cover, until they breed one that is thornless and densely foliaged.

Good suggestion.
I have seen multiflora sucker.

I think R. wichuraiana would be just fine to cover a steep slope. Plant one, and then use cuttings every five feet or so. With time i am sure it will smother any weeds. (It has been said to even smother gravestones). See 1997-104 and 1995-209 & 320 references.

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.

Jay-Jay,
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 off 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

Jedmar,
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'

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.
