Rule number one, is pick the right roses, and they aren't hybrid teas. Period. Sorry.
Rule number two is that once blooming roses tend to need less sun as a whole than remontant (reblooming) or perpetual roses. Having one of these in your garden is generally worth it, because the once a year show tends to be beyond spectacular.
Rule number three is hybrid musk roses, as a class, are more shade tolerant than others.
And Rule number four, they have knockout roses growing in the medians of the highway for a reason.
Okay without further ado, here is the list of roses I know you can grow successfully in under 6 hours of sun, because I do! A * marks a rose I know can make it perfectly fine in even 3-4 hours of sun, as I have them growing in such conditions.
|Ballerina - probably my favorite|
1)Ballerina, Hybrid Musk* (seen blooming like mad in less than 3 hours of direct sun)
2)Any of the Knockout Roses, Modern* (seen blooming in almost no direct sunlight!)
3)Marie Pavie, Polyantha
4)Madame Alfred Carriere, Noisette (Climber)
5)Carefree Beauty, Modern* (mine lives directly beneath a large pecan tree, still covered in blooms)
7)New Dawn (Climber) (this does fine in 4-6 hours, but definitely doesn't bloom to potential with less than that)
9)Eden Climber, Modern(Climber)
10)Lady Banks Lutea, Species
|Carefree Beauty - super drought tolerant too.|
Considerations about my garden: There is no spot in my yard which is dense shade, or even medium shade. Even zero directly light is pretty bright out there (light shade), because I live in the southern US. This makes a difference to some degree. No rose will bloom in deep shade. Some roses, on the margin will get blackspot in the shade more frequently than it would in the sun. I do not have major blackspot issues in my garden, and I 100% attribute that to smart rose choices, because my climate is primo ideal for it, and I have had other plants with blackspot like fungal diseases. I do get powdery mildew badly during the summer on non resistant plants (phlox and beebalm primarily), but my roses so far have been immune. However, all of my roses are on a drip irrigation system or are in containers where the water situation is heavily managed. Obviously, some of these are warm zone only roses, but not all of them.

Do any of you have some good suggestions for the not only 'shade tolerant', but 'shade is swell' rose bush varieties that you have tested with your own eyes?
