Rosa sericea subsp. omeiensis f. pteracantha

[olegKon]

For me it was easy from seed sown 3 years ago, survived 2 severe Russian winters (zone 3) with winter coverage just in case, but has not shown the conspicuous thorns I hope for yet.

Thanks for all your valuable insights good people. I won't bother with seed, I will just have to wait until I meet someone who grows it, online or in person.
