Adult ''Acmispon glaber'' plants are usually killed by fire due to their thin epidermis and broom-like foliage that burns easily, but the seeds of ''Acmispon glaber'' are scarified by fire and readily germinate in the first rainy season after a fire. For 2 to 3 years after a fire in a [[Coastal sage scrub|sage scrub habitat]], the flora consists primarily of herbaceous annuals and short-lived herbaceous perennials, but after the first 2–3 years, ''Acmispon glaber'' generally becomes dominant, being gradually replaced by long-lived shrubs after 5–10 years post-fire.{{Cite journal |last1=Montalvo |first1=A.

Due to their seeds' fire adaptation, ''Acmispon glaber'' benefits from [[Scarification (botany)|heat scarification]] in cultivation. [[Scarification (botany)|Heat treatment]] significantly increases germination rate.
