I have learned now with Aeoniums, as long as the stem is good, I can chop off the rosette that is attempting to bloom and wait for cool Fall weather to plant it, and it will come back nicely
I have two bolters right now..though it is tempting to chop off the rosettes, I just want to see it finish the cycle of blooming. So far it has not been successful to complete it, oftentimes Mother Nature breaks the stem for me.
