Roses are 35 million years old?
Flowering plants first appeared 130 million years ago, which is just over one sixtieth of the earth's age.
Modern humans have only been around for 200,000 years, and humanoids for 6 million years.
How long have roses been on the earth?
Re: How long have roses been on the earth?
Rosaceae split from Rosales about 120 million years ago (in early Cretacious), Rosoideae formed a cluster about 100 million y.a. (between early and late Cretacious), and Roseae (the direct precursors of the roses genera which we more or less know now) split along with Potintilliae and Agrimoniae about 66-67 million y.a. in Paleocene.

Re: How long have roses been on the earth?
Thanks for that information. I was searching online and couldn't find very much, other than China was a big source of roses in ancient times, and that roses only evolved in the Northern Hemisphere. I wondered if that was due to differences in the timing of Ice Ages between the Northern and Southern hemispheres?
I was curious to try to find historic personalities or at least cultures who grew roses, such as Chinese emperors or Mesopotamian rulers, though the Hanging Garden of Babylon seems to have few definite historical sources and nobody is even sure exactly where it was. The Empress Josephine is more recent, and part of the more modern trend for the cultivation of roses.
This gives an interesting summary of the timeline of rose cultivation in China https://www.actahort.org/books/751/751_44.htm
And this gives a clear idea of gardens in ancient Mesopotamia, dating back to about 1,500 B.C. https://plantspeopleplanet.org.au/o1/k1/k2/k8/ though I am still reading through it and can't find any detailed description of the roses they might have grown there, and how they would have differed from Rosa Chinensis.
