Henry, I came across this thinking while attending a woody plant conference at swarthmore college. The college has the Dean Bond Rose Garden and RRD was showing itself. They are attempting a plant diversity approach to the garden. In October, I am going down for a perennial plant conference. I appreciate the place and its plant collections. Last, with your wealth of knowledge and networks. How could I possibly get my hands on Pompone Juane?

Tom Carruth gave a presentation on this at the Orange County Rose Society last week. He's the new curator of the rose garden at Huntington sinced his retirement from Weeks (about a year and a half). Some of the changes looked fantastic. The garden is no-spray and all organic.

Hoovb, You forgot to mention Dennison Morey. J&P had two breeders at the time of Gene Boerner. Denny was on the West Coast. He gave us many good roses, including King's Ransom, Proud Land & South Seas. His Temple Bells became the bloodline for today's ground covers.
Rumor was that Boerner would never allow Morey on the property of the NY breeding station.
Bill Warriner was hired to replace Morey right before Boerner's death.

amanda I didn't know about Dennison Morey and very much appreciate your adding to the story!
I was interested in the historical evolution of a 19th century American company of enterprising family farmers to 21st century corporate "brand" selling product from contract growers. Was just googling around to see what I could find. Anyone else know more? Will the OP forgive the thread hijack?

Frederic M's width would probably be constrained as the deer nibble off anything sticking out past the cages. This grows so fast. It seems almost ideal for your situation. I forgot Sugar Moon, it's as tall as Honor but has a different blossom shape and better fragrance.

The end of the season is fast approaching and I STILL SEE DEAD THINGS! Have all of your JB's come MY way??
Their numbers have dwindled down but each day they still exist. I mash about a dozen @#$*!! daily. Planters and pots being emptied and put away here. Leaves maybe half the trees are down to rake. No fall showing for me-a few perfect specimens on Purple Passion or Heirloom. Disneyland going to give me a few. Hot Cocoa ruined, also 4th of July and my silly old Knockout. If there are no flowers they eat the leaves anyway. sigh...
Congrats Steve-don't give in- even expanding your rosegarden--wowzer send me some of that enthusiasm!
I'll feel better come spring.


I snap off the flower ( breaks at vulnerable spot ) and wait for the remaining green stem to die off, usually to the next leaflet. When that is dead I snap that off. Some roses are harder to snap off than others so I nip those. Deadheading is different than pruning.


In the long run, leaf compost is not a light material. It shrinks away as bacteria consume it. If the potting mix is mostly compost, it becomes a very dense mucky material with poor drainage. The guru on the Container Growing Forum doesn't use compost at all in his more durable mixes. It isn't really a substitute for peat or coir unless you will be repotting once a year in all-new mix.
Of course, it's good as an additive to garden soil or as a mulch. If you mix leaf mold into the soil before it is thoroughly made (18-24 months), it will rob nitrogen, so extra N will be needed. Eventually almost the entire bulk of compost will be eaten up, but a small amount of humic acids will remain as a long-term soil conditioner.

Thanks, Kate ...
Mountain weather seems kind of tricky to me determining late winter/early spring. We always get a winter thaw near the end of January/early February, then winter always comes roaring back with more snow and below freezing night temps. Tricks the roses every year.
I've only planted one rose in fall, and it was from a container to the ground and it had a large root mass. The rose came through just fine. However, both day temps and night temps were 20 degrees higher than they are this year.
I've also transplanted a rose in triple digit temps in July and with a lot of TLC brought the rose through the high temps of summer.
My biggest issue is that this rose is not thriving, so I want to give it the best chance I can give it to succeed. Since the cold temps have arrived early, I am slightly uncomfortable transplanting it in fall. Since it is a modern rose and never really goes dormant, I guess it just has to go through one more winter in its current location. I will try to transplant it before the roses start putting on new growth and when my hoses are out, so that I can make sure it is properly watered.
Smiles,
Lyn
PS .... isn't your late winter pretty darn cold ? You may be tougher than I am .... lol.

Personally I've only dealt with Long ago roses and Riobay. Long ago roses of course is my Favorite. Although Riobay bay sells larger plants some own root some grafted. All plants from both have been healthy, both have answered all my questions very quickly and have made suggestions for plants that would do better in my zone as opposed to the ones I had placed a bid on.
The one other comp. I dealt w/ was the cause of a recent debacle. So I can't honestly pass judgement (yet).
Not sure if this helped

Thank you for the information about using the minus sign to limit searches.
I agree about the patented roses, although the vendor might be reselling a patented rose he or she had bought elsewhere, which is perfectly legal.
I have not bought from Riobay, I will check their offerings next spring.




I think Drop Dead Red is a very good red floribunda, has been disease resistant for me on a uniform bush and repeats quickly. Tom Carruth seems to have some really good roses. Regan's Nursery said it is hardy to Zone 5 and I think it is readily available. Pictured here is its first flush.

OK, the end of the Rose searson is approaching...I'm new to active rose cultivation and would like to be reminded how to prepair for winter (I'm even open to chastisement for my previous neglect of my DonJuan's). I have 3 or 4 DonJuan's that are old & almost dormant due to my neglect (I will do better, I promise!)...the beauty of this DonJuan rose is hard to describe if you haven't seen it.... This week I planted a couple of new DonJuan's along with a Peace climber plus 2 Mr Lincoln's, added 4 ArticFlame's, 2 AlmostBlack and one PopeStPaul-II, plus 2-yellow no-name's... I'd like to know if 2 or 3 inches as mulch for protection on the new plantings will protect them 'till spring - I'm in mid-NC (Durham) ?

Michael, I agree that the burlap doesn't keep them warmer. What I think it does do is hold moisture in and protects them from winds that can dry the canes out. As you said, the only way to keep them warmer is to provide a heat source. But in fact you really don't necessarily want to keep them warmer. They need to go dormant and stay dormant. However, keeping them from becoming desiccated is beneficial.
Mike, 2 to 3 inches is a start, and not knowing much about Durham's climate may be enough, but more would be better. I don't winter protect everything in the ground any more but if there is something new or one that I know is tender I pile on the mulch using something to hold it up and on if necessary. I like to try and go at least 6 inches and have done as high as a foot on a rose that I knew was weak. I've used old, broken plastic flower pots with the bottoms cut off and milk jugs, bottoms off and side slit to get it around the rose. Mounded soil works well and stays in place. Experiment with what you have to see what works best. But don't winter protect too soon. You have to be patient and wait for the weather and the roses to tell you when it's the right time. Some years I have done it in October because it was very cold very early. Other years I had to wait into December before the roses finally went dormant. The point of winter protection isn't to keep them warm it's to keep them evenly cold and dormant all winter and early spring through all the ups and downs of the temperatures until it really is spring for good.


Can Peter Mayle take some shade? I don't really know--except to say that mine get shade all morning--the sun doesn't hit them until about 1:00--but then it is sun all the rest of the day. I sometimes think they would like it better if there were some shade for relief from that late afternoon sun--a killer heat in Kansas!
Oh hoovb--everytime I see a pic of Munstead Wood, my heart goes pitter-pat, pitter-pat! Those dark velvet tones just about knock me over. Love that plant!

Thanks, Pat and hoovb, for your gorgeous photos and Kate and Cynthia for sharing your experience. I think I know what I'm going to do and then I change my mind again.
Pat, your experience is very helpful. I like GD better after seeing the whole bush when in bloom and hearing that the fragrance is so strong. If it can handle heat and humidity that well, it sounds like a serious contender. The old-fashioned nodding look sells it for me even though I don't think that American Beauty blooms nod like that. But to be honest, it was a very long time ago. Oddly, the thing I remember best is their fragrance and this rose sounds like it has plenty of it.
Cynthia, I was afraid that VF would be similar to the other hybrid teas in preferences and disease resistance. None of the ones I've tried here have ever been happy. However, your description of the Austins make them worth considering. Also, I really like FD/Barcelona and would love to use it somewhere, even if I don't grow it in this bed. I was hoping it would grow better for me than the other hybrid teas and it sounds like it may. Maybe I should buy one of each? My husband will love this idea.
Hoovb, that picture very nearly made my decision for me! Wow!
Right now, I'm thinking I will go for Grande Dame and either FD or one of those Austins. But I have changed my mind three times in the last two days so it could happen again. Thanks, everyone, for your help.
