There are two possibilities. Some plants are vegetatively reproduced from plant mutations. These type of plants are called cultivars. Sometimes, these cultivars can produce a stem which reverts to the original plant's characteristics. You often will often see this on a variegated plant that suddenly produces a stem with normal leaves. When you see a reverted stem on a cultivar, it's best to prune the offending stem from the plant.



Another possibility with roses stems (pun intended) from the fact that a lot of roses are grafted to different but hardy root stock. If you plant the graft point to low or you prune below the graft point, you can generate stems from the original root stock. These stems will produce roses that are completely different than the rose you purchased. Where does this stem initiate on your rose? If it is below the graft point, then it is different because it is from the hardy root stock. The graft point will be a swelling along the base stem. Have you recently added soil %26amp; now the graft point is buried?



Cross pollination with a different rose can not be the problem. Cross pollination produces a new progeny in the form of seeds. Seeds produced by sexual reproduction will have some characteristics of both parents. Seeds form this plant can have different flowers because seeds share some genetic material with both parents. Cross pollination can not change the genetic makeup of the adult plant that produces the progeny.
Reply:it may have pollinated with another rose bush
Reply:maybe the bees that pollinated them brought pollen from other rose bushes. just a guess i'm no expert
Reply:I grow Roses myself. I looked in my plaint book and found nothing on this. I would guess that it is a soil problem. Roses need an acid soil to grow well, try feeding your plant with rose food. Your rose has most likely used up everything in the soil. Texas A %26amp; M at Collage Station used to do free soil testing. You send them the sample and tell them what your growing and they would tell you what to add to the soil. But I beleave your rose is saying feed me A tip, when cliping off old buds, clip them were the steam comes to 5 leaves, it will make it bloom faster. Roses take a lot of T.L.C. Keep old buds trimed off, dead wood trimed out and watch for any sign of an unhealthy plaint.
Reply:sounds to me like your rose brush could have been grafted. And the stock plant was pink and it's now growing as well as the graft. you should let the pink grow if that the case cause the pink will take over and the red will die out.
