So I have decided to grow a couple roses and have selected what I want to grow. Other than enjoying them they will serve other purposes. I'll be using the peddles and hips for rose water and rose oil.

That all aside I am a noob to all of this but am very excited to get started. The two varieties I have chosen to grow are "The Queen of Denmark" and "Dog Rose" (Rosa Canina). Here are my questions:

1. I have located an online source to buy "The Queen of Denmark" but cannot find a place (especially in the US) that sells Dog Rose.
1a. Do any of you know where I could purchase a Dog Rose?
1b. I just so happen to have a bag of dried rose hips I recently got from Amazon. Will I need (can I even?) to use one of the seeds to grow my own Dog Rose? If so, how/what do I need to go about doing that? I thought I read somewhere that you need them in the fridge for a period of time.

2a. Once I get my Queen, how should I prep the hole and soil where I will be placing it?

I think that should be it for now. Thank you all for the help.
