Anything gray, green or brown introduced before Brown Velvet. They will root, some will almost grow, but not as well as they will budded on a suitable rootstock for your soil and climate types. Henry Fonda was to be a New Generation own root rose until J&P discovered it doesn't make a decent enough plant that way. Midnight Blue is a far superior plant budded than own root. Even with the information you're going to obtain, you're still going to find quite a few nurseries who offer them own root. Just because you can obtain it own root, does not mean it is good that way.

Then, there is the issue of whether it is suitable for your soil and climate own root. Some have definite preferences, just like we do. Kim

Thank you Kim and Karen. I did by Just Joey from a vendor selling it as own root and from that experience, you are right Kim, I have learned not to believe they will all do great just because the vendor is selling it. The hardiness is not as much of a concern in Oklahoma,although last winter might prove me wrong if it keeps repeating, it's the extreme heat we have every summer that needs to be taken into consideration.

Own root hybrid teas don't do well for me at all. A friend a few miles down the rose has a nice own root of Hot Princess that was propagated by a friend of hers. I stick with hybrid teas grafted on R. multiflora rootstock.

None of mine has done well enough to recommend. Well, Silver Jubilee looked like it was doing OK, but I discarded it after two years because I didn't like the flower and the plant wasn't as resistant as it was claimed to be. Naga Belle after 1-1/2 seasons is doing pretty well, but it's too soon to say..

I'm sure there are plenty of exceptions, but a good rule of thumb is to get grafted HTs if they are available,especially if you garden where each winter sets the tender roses way back.

You're welcome Judyok. The main factor is how vigorous and extensive the root system is. I learned early on from raising seedlings, the sick, weak ones had few roots, or very weak systems under them. The healthy, vigorous, productive ones had large root masses under them. Root stocks provide just that, extensive roots providing superior vigor, not always and not everywhere, but generally in many places and many varieties. The common root stocks also provide a more uniform performing product for the areas where those stocks are suitable. They have their own sets of issues, as many here will attest, but for vigor, budded is frequently better in more severe situations.

Now, of course, that doesn't take into consideration planting deeply to protect the union and allow it to go own root. Any benefits desired from a suitable root stock are lost once the rose goes own root, if it ever does. Once own root and if the stock dies as is frequently suggested it will, you're back to the own root plant with its own set of issues.

The root system mass and vigor I've proven repeatedly by taking weak seedlings and budding them. It is down right amazing seeing the results. From little root mass and a weak, more sickly plant to a budded plant with the increased, vigorous root mass and a significantly improved plant performance. It is NOT a cure-all, nor will it take a dawg of a rose and make it good, but it often improves performance, aside from the undesired stock issues. Kim

JudyOK, is there a specific reason you're seeking to avoid grafted or budded roses? Just wonderin'. I prefer ownroot because all of my roses are in pots, and ownroot will often take longer to threaten rootbound status. Dr. Huey is my least favorite rootstock, because those taproots want to go straight out away from the base. As for Just Joey, I gave up on it too because those beautiful fragrant blooms were not frequent enough and would shrivel in the heat in a day. Have you tried Over the Moon? Just a smidgen more golden but similar and a nice fragrance on a big bloom. Mine is on Multiflora, still in a pot, so I don't know about its own-root performance. Prairie Sunrise is almost the identical color, similar fragrance, if not as intense, pretty. Blooms are ruffly, plant is compact but does fine on its own roots, blooms don't seem to last any longer, but they are more plentiful. Gotta spray for blackspot, though.
My most vigorous ownroot hts or granifloras have been Paradise, Gold Medal, Helmut Schmidt, and Fragrant Plum; and more recent really promising acquisitions (purchased in the past year and a half) have been Pope John Paul II, Olympiad, Elina, and Tahitian Sunset.
The general guideline I try to observe is that the better branching and bushy a variety is, the more likely that it produces a vigorous root system. So hybrid teas that grow upright but don't branch out too well might likely not be as vigorous on their own roots. Maybe that's why most floribundas do just great on their own roots; they are already bushy growers.

That is a very interesting observation, Mike, thanks! Something I'll have to cogitate on a while and see if I can find a correlation between them. Kim

I've grown Just Joey own root and grafted. Neither one was what I would ever call vigorous. Sometimes a rose just isn't "lively" and even a good graft can't get it to produce like a Floribunda. I have one Hybrid Tea named Lady Mitchell (Harkness) that is the only own root HT that has survived the Oklahoma weathers ups and downs. She's a good one for container culture being short, round and bushy, and that's where I've had mine for 7+ years. When she survived the subzero winter last year unprotected, I bought another one from Heirloom. My kind of rose {{gwi:223272}}

Sorry I'm late back responding, been busy past couple of days.

Mike in New Orleans: All of my hybrid teas are grafted and I've been happy with them. The better branching a bushy habit might explain the Austins. I've purchased a couple of Austin's that are own root and they have been growing vigorously for a few years now and are virus free and that might be my most motivating reason for own root (virus free)but not if own root Hybrid Teas means puny and struggling. Thanks for the rose recommendations I will check them out.

Maryl: I appreciate the recommendation from a fellow Oklahoman. I will check out Lady Mitchell.

Kim: I think I'm going to try an experiment with a couple of the recommendations and see how it goes with a couple of other hybrid teas

Diane nj and Michaelg: I've am wavering and am at almost the same conclusion that hybrid teas are not the best on own root. I'm going to try a couple more and give it one more chance. I'll let everyone know how it goes after they are established

I can't imagine anyone offering Just Joey own root. Although it's a beautiful rose it was the weakest growing rose I ever had and it was grafted on Dr. Huey.

'Just Joey' is one of those roses that is very good in a very few locations. So good in those few locations, in fact, that it is one of the handful of roses that have been immortalized in the World Federation of Roses' HALL OF FAME.

Other HALL OF FAME roses that are absolute dawgs in many, many locations are 'Iceberg', 'Pascali' and 'Double Delight'.

So, when it comes to 'Just Joey', the best advice for most gardeners is "just don't . . . ".

'Just Joey' grafted wouldn't grow for me either.

I have not grown a single HT that performed as well on its own roots as it did as a grafted plant. You have to remember that 99.5% of all HTs that make it to commerce were tested only when budded to a different rootstock variety! They were never intended to be grown own root. That tells you most everything you need to know ;-)

Trospero, Thanks for your comment. I've long wondered if I might be the only gardener who, in spite of many attempts, NEVER has had a satisfactory experience with an own-root HT -- and that includes the New Generation plants that J&P offered. To tell the truth, most own-root Floribundas haven't fared any better for me.

It appears to be very climate, soil and water and varietally variable. Those which were introduced before budding was the favored propagation method, usually performed well in the old garden, unless chlorosis was an issue with them as the conditions were very alkaline.

Many of the initially budded ones performed well there, too, but once the soil had been sufficiently amended with enough manure and water was laid down in abundance, most did quite well. The main exceptions were those which were just weak varieties to begin with. Most of them did much better when budded on Huey as that is the stock most suited to these conditions. Also, many, whether good in the mid desert own root or not, just didn't perform well in the colder, damper soils along the coast. It was quite interesting observing what did well with heat in the desert soil, then nose dived at the coast. I'd imagine your conditions in Oregon would be more like the coastal conditions here, Paul, only much more extreme. I can well imagine them not performing well, or as well, for you there own root. Of course, I'd also expect the increased fungal pressure you experience had a symbiotic relationship with their performance. Growing weaker would make them more susceptible to attack, and stressed by attack, they would perform more weakly. Very interesting, thank you! Kim

Well after hearing more negatives about own root hybrid teas I think I will just stick to Austin's for own root. No since tossing more money at it.

Judyok, After carefully reading and trying to comprehend all the above posts, I think you've reached a very wise conclusion.
