What happened to my Tea Hybrid Rose bushes?

I'm new at gardening and last spring I planted 20 rose bushes. Some where dark red (a pure red), and some were a passionate perple and then i had some pink ones with white lips, and some yellow ones. All of these were mostly one color. But by August I startes notecing the purple roses started lookin more redish and the red ones were looking purple/pink, one bush had 6 purple buds and 4 red ones, although when i bought it they were all red. One of my yellow roses started to just have flowers that where Yellow with red lips. Is this because they were cross polinated in my yard. I thought it could have happened in the greenhouse but for 3 months they were a single color and then they slowly started to change.

No they are not cross pollinating. That involves the seed and you haven't been collecting and growing your roses from seed.



Some color change may be due to season change or maturation of the plant. For example when temps cool a yellow rose might develop a slight red blush.



What I'm really worried about is it sounds like some roses have reverted back to their root stock. Most hybrid teas are grafted on to a different root stock to accommodate all the various soils across the nation. Two such root stocks are Dr. Huey which is a dull red climber with about 8 petals and a yellow center. Other roses are grafted onto a wild pink rose of about 5 petals . Any growth originating from below the graft, the bump on the stem, will be the root stock. It is so vigorous, it can kill off the top of the rose, your selected variety. Of course if the top died say from winter freeze, then all you'll see is the root rose.



Get to the main stem and carefully dig down beyond the bump (graft), remove any canes originating down there.
Reply:All of them are right about what they said. Temperatures, soil conditions, watering conditions and age of the plant all can change the color. You may want to also put down some ant deterrant as they love to eat up the root systems of almost any plant. This may be part of the color change as well.



Make yourself a chart on when to water, feed, and remulch the roses. This consistency will bring back the natural color.

You only need to remulch in early Spring and late Fall.
Reply:roses do not cross in the garden.... getting a cross pollination and growing a different color takes some work!... and seeds planted... and years of growing.... did you leave the tags with the roses?... could you have forgotten which one is where?.... there COULD be a color change with soil ph or lack of fertilizer, but it wouldn't be as some you mentioned... would be mostly looking faded.... not tipped in a different color, etc..... grafted ones COULD have sent up some rootstock and those roses would be vastly different from the ones you chose and planted.... you'd have noticed long straight odd canes, tho, if that was the problem..... and usually that doesn't happen unless there was damage from freezing or the top of the graft just died..... I suggest you go back where you got the roses and ask your questions there... [provide pictures or samples if you can when you go to talk to them).....
Reply:some roses change color as the rose blossom gets older. Literature on that rose should tell you. I have had roses with one branch a different color than the next and the next year back to the color it should be but then this was a shrub rose on its own roots. Just wait and see what happens this year, they may well be back to the color they should be
