1. Short flowering period for mine, at most 1 1/2 weeks

2. Is SW Missouri too warm for it? Can't answer this one but in zone 3 dry foothills it is at home.

3. How large will it get? Very large by my standards, easy 8 feet by 5 to 6 feet. I just finished pruning (more like sawing - used a tigersaw) canes that were an easy 2 inches in diameter to keep it within my property.

4.Does it sucker? Moderately for me, as defined by new canes show up one to two feet away.

Magnificent species specimen for a large space. It is the graceful form, color of the leaves and "nut" colored hips as they ripen that make it a winner ... plus completely hardy in my zone.

I've seen it in my area, which I think is zone 8, but we do have zone 7 plants growing happily here, lilacs for example do well. That is, comparisons with our northern Italian hills aren't necessarily valid. We have relatively dry summers, in terms of atmospheric humidity, and usually adequate winter chill without reaching hard frosts (under 20F) often or for prolonged periods. The plant I saw was smaller than Riku describes, but a respectable shrub, perhaps 4'-5' high and wide, and it looked healthy.

Here in 6b (not in my garden) I saw it being very happy and growing to approx 10-12 feet in all directions, like a small tree with multiple canes. Hips are amazing on this rose.

I am in zone 9 and have had it for a little over a year now. It struggles a little here but it does ok. It bloomed for at least 4 weeks this Spring. It seemed like it was longer than that but I didn't keep track of the time. It did not sucker at all the first year. I am using it for hybridizing so even if it struggles a little I will keep it. By struggle I mean it loses some of its leaves but it still looks good. I don't think you would have any problems with it were you are at all. Good Luck

Oh my, I think it's way too much of a monster for my yard. I'm disappointed. I think I need to buy another rose to make myself feel better. ;D

In Sacramento, I've grown it for three years and it still is a modest clump of half a dozen six ft tall arching canes. Blooms lasted no more than a couple of weeks, but hips looked good all summer. The hips shriveled early in the fall, unlike other roses where they just now are ripe.

Must be more manageable in warmer climates. I was warned not to put it against a west-facing fence, but did because it was the only place I had. It's shown no sign of burned canes or dropped leaves, but maybe the heat and sun are why the hips went so quickly. On the other hand, it set hips very early in the year, so maybe they simply were just good for 4 or 5 months.

I do keep reading it prefers a cooler climate.

Anyone in a non-southern climate know if it can be kept trimmed back? I'm not reallllly sure if I'd want to bother. I guess it depends on how quickly it grows.

This is a monster rose, and I think any attempt to contain it would spoil the form. R. glauce was planted along the entrance to the Columbus, Ohio Park of Roses (zone 6) where it made an 8 ft. x 6 ft. hedge. I was always tempted to steal one of the suckers but never did; there were just a few. (Maybe others helped themselves, eh?). Current Buckeyes, is this rose still there?

I planted one spring 07 and it did not bloom this spring and didn't grow very much either. I seems to be struggling for whatever reason.

My ownroot R. glauca is a slower grower in acidic clay on a dry knoll. I can handle slow growth as long as it doesn't go backwards.
The first R.glauca I saw was in North Platte Nebraska, a bush planted by Glenn Viehmeyer back in the 60s. It was in a field at the hort farm and was mowed around in a grid pattern. It was five feet tall, three feet wide and a dense mass of stems. But it was a survivor of over 40 years. It was planted in sandy soil that was reworked loess, so fairly calcareous, with no winter protection.

It sounds as if pampering makes for much larger bushes.

... acidic soils and warm humid climates ? mine is in alkaline soil and gets some water once in awhile and nothing else as it does not need it. For scale the man in the photo is 5feet 10 inches and shrinking as he reaches pensioners age

This is the bigger of my two bushes I think about about 1 or 2 years ago. The canes this year reached the eaves trough you can see. It sounds from Cass that the grand champion resides in a cemetary in England where Karl Marx sleeps and is a tree.

Unlike other species I have dealt with that do not belong here, this one gets vengeful when pruned and throws out new basals like no tomorrow.

Wow, that is a gorgeous rose. I love those leaves.

Now I know what plant I wish I had tried to grow against my house in Houston. Riku, that's such a great color combination.
I have better soil up at the house, especially an area that has lots of Native American worked stones. I've often thought of the centuries of women who sat there, with the mountains in the distance, working the deer skins so near the old paths of deer and men.
Your mature rose has the right look for that place.

I keep ours at about 5 ft by 3 ft blooms about 3 weeks hips are very nice contrats in the fall

Gets big in zone 4 Minnesota and it blooms for 2 weeks, max. It has many pretty hips, but beware -- this rose is very fertile. I am always pulling out seedlings even though I removed the plant years ago. Its main purpose is to reproduce by spawning bazillions of offspring all about the place.

dr andre,
are the seedlings purple leafed or green leafed?
Any idea if they are self pollinated or who the pappy might be?

All the seedlings have purple-gray leaves, identical to the proud parent. I was assuming self-pollinated, but I have an alba, an Explorer and a rugosa hybrid nearby, so they could be parents, too, I suppose.

I recall reading somewhere (Beales?) that glauca tends to dominate the appearance of its hybrid offspring ('Sir Cedric Morris,' 'Carmenetta') to the point of even upstaging Rosa rugosa

R. glauca is one of the Caninae section roses. These roses donÂt divide their chromosomes evenly. A normal tetraploid rose has 2 sets of chromosomes in the egg and 2 sets in the pollen. While R. glauca is also tetraploid, it has 3 sets of chromosomes in the egg and only 1 set in the pollen. ItÂs also quite self-fertile. IÂve raised deliberate hybrids, and they are often hard to distinguish from the pure species.
