What type of rose is this?

My great grandmother had a beautiful rose bush that bloomed different colors every year. Sometimes it would bloom diff. colored roses at the same time and once the rose bush bloomed an ice blue rose. Can anyone tell me the name of this and where can I find one.

What type of rose is this?
"Joseph's Coat" rose has multicolored roses on the same bush %26amp; blooms all summer:

I've grown "Joseph's Coat" %26amp; was amazed at how many color variations this plant had. It changed from day to day but mostly in the pink-red-orange-yellow tones. It even can take on some purple hues...as the last photo shows. I would have really enjoyed seeing a blue rose growing on a "Joseph's Coat"...but I've never had that priviledge.





You can get "Joseph's Coat" at most garden centers, even at Home Depot %26amp; WalMart.





If you don't think that your rose bush is "Joseph's Coat", here's a guide to some of the best loved roses of all time, maybe you'll find it there:

Reply:I've never heard of a rose doing this, however a flower called Hydrangea does this. It reacts to thePH level in the soil to create a blue or pink color and sometimes both. so maybe this is the case of when a rose is not a rose?


Or other possibilities are that it was a grafted rose, and the root stalk sprouted and showed it's roses in a different color. But you got me curious and so I did some digging, and apparently roses can 'sport'. This is when a genetic mutation happens and a rose will have a totally different color.


And last but not least, the color and intensity of color on a rose changes throughout the season, the warmer weather will usually create a bleached affect on the roses, and more intense colors are usually seen during the slightly cooler months.





Hope this helps.
Reply:Actually. from my experience as well as the experiences list bellow, roses can be influenced a little by soil acidity or aluminum, but the main difference is that most nicer roses are grafted onto hardier root stocks and any time erosion or mulch levels, or rodent incursions expose part of the root stock below the graft, the original root stock will come up and bloom - resulting in a less interesting and less vigorous color, but also still a rose. It often takes a review of the leaf shape and flwoer color to determine whether you are getting the original intention or the root stock - normally once the root stock is exposed, it is hard to get it to support the hybrid properly and the hybrid dies - but I have re-planted a rose deeper and cut off the root-stock canes at the right time (accidentally) to make the rose return to the original configuration where the vigorous (wild) rootstock was subjugated to the hybrid tea rose that had been grafted to the top of it. Harsh, I know, but if a rose is producing something cool AND something pretty plain but vigorous, cut the vigorous growth fastideously and plant it deeper or mulch it higher until it stops trying to make light pink blooming stems from the root stock and makes the proper hybrid stems from above the graft! It is just the nature of the beast with roses - and they have been grafting root stocks onto prettier but less hardy roses "forever" so you grandmas was also probably a grafted rose.


But I am an optimist, so try your question one more time under a slightly different heading at about 6pm Eastern Time (US) and see if someone brings up a different answer.


HOWEVER - the second link I have listed does talk about roses that offer more that one color - so look at that one for more information on what is known to be available.
Reply:No but the acid in the soil changes hydranga colors. Maybe it is kin to it.LOL
