Rose propogation from bouquet.

I don't know the tipe of rose this is. I gave my mom a bouquet, after 2 weeks this guy had sprouted a decent amount. I decided to try an propogate it. I moved it out of the vase and into a cup of soil where it's been for about 3 weeks. I used rooting hormone. I don't really now what else I can do to improve its chances.
