In most cases, serotiny – retaining the seeds in a hardy capsule or cone, which opens in response to a particular “trigger” – is an adaptation to ensure a plant species’ survival in a fire-prone environment.
Serotinous plants exists in both the Northern and the Southern Hemisphere, but Australia is home to the overwhelming majority – WA most especially.
More than 75% of the world’s known serotinous plants are endemic to WA, mostly to southwest WA.
