thank you for using Ask Extension.
I'm having a hard time visualizing the actual problem. It sounds like you may have suckers coming up from the base. It's doubtful the bulbs or iris are a problem unless they are so thick that they prevent the smoke bush from getting adequate water and nutrients. Are you able to provide a picture of the plant through an attachment?
I would also caution you from comparing with another shrub in a different yard because the microclimate/environment can be different.
