I like this daring approach to getting more plants! Also had to look up ‘zombie leaves’ and apparently they are sold as plants by themselves. From an ag extension school in NC::
Some, but not all, plants can be propagated from just a leaf or a section of a leaf. Leaf cuttings of most plants will not generate a new plant; they usually produce only a few roots or just decay. Because leaf cuttings do not include an axillary bud, they can be used only for plants that are capable of forming adventitious buds.
