Unlike many anemones, this species only reproduces sexually. They release eggs/sperm in late spring-summer, producing pelagic planktonic larvae.
Larvae 1st settle at around 3 weeks old, most often in rocky areas or mussel beds. Once they attach to substrate, they slowly develop pedal disks.
Sexual maturity reached at 5 years old.
Females release thousands of eggs at a time & do so a few times within short period.
