As you tend your garden this summer, spare a thought for Alison Vaughan, responsible for no less than 1.5 million precious botanical specimens.

As collections manager at the National Herbarium of Victoria, which dates back to 1853, Alison stewards a vast archive of past and present biodiversity that illuminates our social and ecological history and provides tools to build a better future.

How is the Herbarium at once a colonial institution and a resource to remedy environmental ills of colonisation? What does repatriation mean in the context of botanical archives? And whose are the hidden hands that built this continent’s oldest settler scientific institution?
