I believe my rosa rugosa has self-seeded. Or is it possible to have a
runner? I've got what appears to be a new shoot about a foot away from
my existing rosa rugosa.

My question is - how long should I wait before I move it somewhere
else? Right now, it's about 8" tall. I can't leave it where it is for
very long, since it is in between two rose bushes.

Thoughts?
