These are ShiShi buds.  In a matter of weeks or even days all of these buds will turn into flowers.  It is super important to remember this while doing your fall cleanups. When you trim the plant now, before it blooms, you will be cutting and removing the buds which create the flower.  Wait until the January time frame when the plants have completely gone through their bloom cycle. This is when you want to trim and feed them. The plant is not meant to be a manicured one so in a lot of cases they will just need a light trim to get any limbs that have outgrown others.  Hope this helps!
