In all honesty, your rose looks like the invasive multiflora rose and not the Osiria "Ruby" or the miniature "Ruby Ruby". The Osiria Ruby is a hybrid tea rose and grows to 3 ft or so; the miniature is smaller, 2-3 ft. Growing a hybrid from seed never reproduces the parent plant just like 2 human parents don't produce clones. Given it's size, it should be blooming by now if it is going to. Containers for roses of that size have to be wide and deep. You should be pruning annually to encourage it to bush out. Wait until next year to start. Give it 8 hours of direct sunlight daily. The following is a good article on growing container roses and references the Osiria Ruby. https://www.heirloomroses.com/info/care/how-to/rose-container-gardening/
