There are individual roses that don't do well on their own roots. I'm not sure if I could recognize them in your list,as I just know a few, but maybe if we all put our heads together we can help.

I guess I should say are there types such as HT's or Ogr's or floribundas, etc that are better on own root or grafted? I just got Crepuscule and Earth Song on own root.

Tammy, it really depends on the rose. Lots of people make a very general statement that HT's do not do well own root but my Sutter's Gold and the Radiance clan are all very vigorous own root. Sutter's Gold is a huge bush over 7 feet tall! I think you will need to ask about specific roses because generalizations about "all" of a specific type of rose doing poorly own root aren't true. I think that climate, the particular rose and other factors determine how own root roses will perform.

Oh, my Crepuscule and Earthsong were both own root. Both are big (especially crepuscule), beautiful and healthy.:-)

I think it also depends on your climate and soil, too. An own-root HT may do fine for one person and terrible for another.

It seems like most roses do okay own-root around here, in northern Illinois.

Here they say only grow roses on fortuniana. But I grow Austins own root (12 different varieties) and they are all doing well. Some have been around for a few years and continue to do well. I have heavily amended sand.

My general experience with own root HT's has not been very good. The own root New Generation roses I got from J&P however have always been very good roses. I think they are pretty selective of which roses they offer as own root however and don't just own root them all. Most of my HT's are budded on multiflora rootstock and I find them to be more vigorous and healthy than the majority of hybrid teas.
Mini's and mini-flora's however for some reason seem to be just fine on own roots which I find very strange. I am going to try some mini's that are budded on multiflora from Palatine next year and I am anxious to see if there is any difference in the way they perform than the own root versions of the same roses.

Meanwhile I deliberately purchased own root HT's specifically because they were own root, and have been happy with both. I did so because I worried about whether my winters were occasionally too severe for HT's. The freaky winter of '06-'07 killed both down to the roots, but they both came back and both have bloomed this year. I'm not sure that would have happened with grafted HT's, even if I had buried them well. (It really was a freaky, freaky winter - eerily mild until it suddenly became brutally cold in February.)
