How did my rose bushes cross pollinate?

I have 3 bushes about 5 feet from each other and all of whom are near a camelia. One is a regular type long stem, bush variety, purple/pink in color. One is a climbing, cluster, english type rose, white in color. Then I have one that is also a climber but of long stem variety, red in color. I moved the long stem climber to a trellis on the front of the house but left the other (white %26amp; purple) where they are. Otherwise the white %26amp; purple had been in ground together for 2 years and the red was there for about a year before I moved it. This is where I get confused. The roses are all doing great, a little black spot but nothing that cant be handled; growing like crazy. Well I noticed that off of a new shoot my white cluster was budding red roses! Not only that but my long stem red had a single white bud on it albeit alot smaller than its normal bud. I waited to see what I thought would be red english type roses bloom but instead what bloomed was a rose more like a shrub rose but not....

those who tell you about rootstock are right on the money.... get rid of the odd rose branch clear down to where it comes from on the plant or it will take over and your 'good' rose will die..... note that the leaves are a little different and the stem is a little different and there's more or less thorns on that odd color rose.... then keep watch on the plant for any that pop up again.....





the rootstock roses can be nice, but that's not what you paid for, right?.... here's a picture of the red rootstock that's used a lot... Dr.Huey...look like your red one?..

white ones could come from this kind of stock.. the multiflora wild roses....

these rootstocks give the upper plant a lot more 'grow-ability', so they are a good thing.... just not what you want to see in your rose garden if you grow 'hybrid teas'..... *smile*........

Reply:Bees! =) My yellow Roses had a touch of Red last year - from my red Climbing Rose. =)
Reply:Bees do that free of charge. But, it usually takes a few years.
Reply:Two thoughts.......but first I'm not sure exactly where this changling happened. If it is coming from low down, like from the ground, then what you are seeing is the root stock. Most modern roses are grafted onto a more vigorous root stock. The grower (you) must be mindful of any new growth that comes from below this graft as it is the root variety which is almost always more vigorous than the top selected variety and will eventually overrun the top. One of the most used root stock is Dr. Huey with is a red climber. Remedy is to dig down and remove the sucker back where it originated below.





The second thought is you have a sport.......that is a mutation. This occurs within the plant. Not surprisingly, this is how many new roses came into being. The sport or mutation was vegetatively propagated to make sure it remained steady and didn't revert back to the original plant. If steady and deemed worthy for production, a new rose was born. However, sometimes insect feeding can cause some weird miscoloring either directly or by passing on a virus into the plant.





Mostly I'm thinking you are getting suckers up through your plant. Time to get down to ground level and dig around and see who is from the roots and who is from the graft.
Reply:just enjoy the bonus. it happens spontaneously sometimes. it usually takes years to see blooms though.








however, from what you describe I suspect the following has occurred.





A lot of roses are not grown on their own roots but are grafted onto a hardier wild ( shrub type!) rose.


I suspect you are getting shoots that are coming from that rootstock and this is what you are seeing.





If you like them then let it be.
Reply:This is nothing to do with cross-pollination. That would result in brand new plants growing from seed -- not shoots of a different color on the same plant.





It is likely that, like most cultivated roses, the plants are grafted onto roots from a different type. The roots of some cultivated roses are weak so breeders graft them onto strong wild roots to make them grow better. Check where the new growth is coming from. if it is from below the ground level or below the graft junction you are getting the flowers from the root. Cut it off! It will grow more strongly than the cultivated roes and eventually kill it.
