The year 1833 is an auspicious date for lovers of plants and gardening.
This is when the first experiment testing a Wardian case occurred.
Two wooden boxes carrying ferns and grasses travelled from London to Sydney on the deck of a ship.
Amazingly, the plants survived the six-month journey, where previously they would have perished.
The experiment revolutionised the transport of live plants around the globe.
As a result, mangoes, orchids, roses and rhododendrons were able to make the journey to Australia and take root in gardens and as crops.
The impact of the Wardian case is still felt today — and its legacy is complex.
