Yes, it's very easy. I have done my white ballerina and lavender ballerina lavenders, but couldn't find my rooting hormones. I tell you, it's amazing that I can find ANYTHING, as I have things everywhere.
I have also done some hydrangeas. I never liked hydrangeas, but no longer.. the serrated white one rather tugs at my heart's string .. I need to do salvias whilst I am at it.
@Logan but you don't need to do it as you have tons of lavenders.
