Age of rose cuttings
I've been lurking this newsgroup for a while now and I finally have a
question. Last spring, I successfully started two cuttings out of five from an old rose bush in my yard (I'm guessing at least 20-30 years) and I'm now wondering how long I can expect the starts to live compared to their parent. Are they already as old as their parent root stock or has their genetic time-clock restarted as if they were seedlings. Not that it matters since they will all probably outlive me, but I'm really curious if there's any research on the subject since the cutting starts are genetically identical clones of the parent plant.

More tales than hard research to my recollection. Some of the cloned animals, such as Dolly the sheep, were reported to show signs of acelerated aging among other abnormalities. When it comes to plants, I recall reading that fruit trees that were grafted from mature trees would bear fruit sooner than seed grown plants of similar age and size because somehow the grafted branch "knew" it was old enough to bear fruit. However, many seed grown roses as well as cuttings seem to want to bloom right off the mark. It is probably a non factor when it comes to roses. I have seen many, many roses die, but none of old age. It is an interesting question. I will ask my niece who does research at Davis if she knows of anyone doing work on the subject. I probably won't see her till Christmas though.

Roger, even if the new plant had an age of 30 years, the rose bush, if given the proper nutrients, sunlight and water, will outlive your grandchildren. It has been mentioned in this newsgroup several times, that there are rose bushes growing in colonial gardens that are almost 200 years old. Sameer |
