I got some cuttings of a sentimental beautiful peperomia obtusefolia plant a few months ago. I took off the lower leaves and the cuttings are doing great. Just for fun, to see what variegation would come of it, I planted 6 lower leaves into soil. They are now very well anchored and growing. But still no plant to be seen. How long do you think leaf propagation takes for peperomia?
