miniature rose bushes – in pots.
I bought a dozen of this tiny blooming rose bushes at the grocery store, and its Fall here and the blooms are almost gone. I have kept all the little bushes in my bay window where they get a little of the morning sun. I want to keep them exactly where they are until spring. Can I keep them till spring and then plant them in the big garden forever? Can I just water them to keep the roots alive as I would my other plants in the bay window?

As explained in the attached article, "miniature" refers to the size of the bloom, not the overall plant size. https://www.gardeningknowhow.com/ornamental/flowers/roses/miniature-rose-miniflora-rose.htm
