Australian Plants as Weeds. Afternoon talk

On Sunday 28 April 2019, the Friends have invited Geoff Carr, a botanical consultant, to talk to us about the problem of Australian plants which behave as weeds.

Come to the Auditorium at 1.30pm to register and to have a coffee or tea.  The first session will start at 2pm.  Gold coin donation .

Over the years it has been suggested that gardeners should plant Australian species rather than introducing non-Australian plants in their gardens. These plants are known to ‘jump the garden fence’ and become ‘garden thugs’ or environmental weeds in our bush. To avoid this problem it is often suggested that we plant Australian species in our gardens.  Does this prevent the problems of weedy plants?

Geoff Carr is a founding director of Ecology Australia and has been a botanical consultant for 39 years.  For many years Geoff has had an interest in environmental weeds research and weed-risk assessment, and has an extensive knowledge of Australian species that have become weedy. Of several hundred Australian plant species naturalised outside their natural range, some are the most catastrophically invasive of weed species, notably Sweet Pittosporum (Pittosporum undulatum), Coast Wattle (Acacia longifolia subsp. sophorae), Coast Tea-tree (Leptospermum laevigatum) and Bluebell Creeper (Billardiera fusiformis).

Another potentially serious problem is invasion of foreign genes, i.e. hybridisation between introduced natives and in situ populations of related species; this is especially an issue in Correa and Grevillea.
