Realized all the ones I had inside grow notched leaves, because I had two different varieties on the deck and only took cuttings from one planter. The smooth-leaved vine is also the one that flowered. So I made sure to get some cuttings of that as well:
My sunny winter window spot is getting crowded with plants now. Can see here behind the sweet potato vine, stevia I have cut back and brought indoors, and two second-generation aloe veras (one is growing pups now!).
There's also pepper leaves on the side, and under the sweet po vine, that little succulent that grows babies on its leaf margins, kalanchoe.
