I don't know much about roses at all, but would like to start growing them. Is there such a things as a true blue rose? Doesn anyone have a cutting or seeds they would like to share with a beginner? Also, if there is such a thing as a blue rose - what is the real name of it?
There is no such thing as a blue rose. The gene for blue is missing in the rose family. Genetic research is being done however and researchers have been trying for years to create a blue rose. There are roses available such as "Blue Girl" that have a bluish cast to them they look lavender in color.
I have no cuttings right now but should be able to post some in a few months when I begin pruning.
Here is a picture of my first "Blue Girl" rose. It's pink/lavender with a bluish cast, but I'm not thrilled with the petal configuration. Also this rose is a very tall species. It's at about 7 ft right now. Is it ok to cut it back or should I wait?
You can cut it back now, it's not going to harm it. It will slow down the rebloom if you choose to cut back now.
I often sort of prune and deadhead at the same time to keep some of my big roses under control.
Photoshop, yes. A good practice when looking at pictures in catalogs etc., is compare the background and foliage. You can usually tell when someone's been monkeying around with the picture in order to highlight the 'blue' in the rose's color.
If you're new to roses you need to get a little pamphlet or book (perhaps from the library or perhaps the racks at Lowes or similar) because roses are a bit different from most plants. Being a good general gardener doesn't necessarily equip you to do justice to roses.
Not that they're impossible or difficult, but because there are little but important differences you need to learn about.
There are blue roses but their is no such thing as a TRUE blue rose in nature as the color blue is non-existent in the rose bush/tree family. At least that is what has been said in every article of research I've been able to find on the truth about "blue" roses. You would think that since purple is a viable color in roses that blue would be too but for some reason that is the 1 color roses cannot be found. All the roses that you see in photos that are "blue" are either Photoshopped exaggerations or are cut roses that were put in a vase of water containing blue food dye.
I'll search around and see if I can find the scientific article that I read about roses and why there are not any true blue roses only roses being called blue when they are really a purple, lilac or lavender. In the mean time I hope this helps :)
