I'm not going to try storing any cuttings for later rooting, I'm just putting my cuttings into water now. I think some people keep rooted cuttings on their windowsill most of the winter. Sally (D) recommended that I keep the two fat "trunk" cuttings. I'm going to keep some of the smaller pieces also (they still have leaves and some have blooms, because I panicked and cut them on Monday). I'm using large (2-3 quart) containers and setting them on a heat mat, but I doubt they need the bottom heat. FWIW, the blooms are opening just fine on the cut branches.
