Roses are not difficult to grow from seed, if you do it right.
[ . . . . ]
First, be aware that each rose seedling is a new, never-before-seen variety.
Well, after reading
The Botany of Desire: A Plant’s-Eye View… and doing a little research in rose hips as seeds, I decided to see what kind of strange variants I could get from my rose bushes. I am fortunate in having three good sized hips (the size of a cherry) from three different roses. None of the plants are identified, though my garden mentor — my father — suspects one is a Queen Elizabeth. That’s the one I just worked on. It occurs to me now I should have used the digital camera, and I will on the next one I do (I have found no pictures of the process).
I simply followed the instructions on the page linked to above. We’ll see what happens, come the new year.
