    Hi there Tess
    We’ll try and visit the Monash garden soon. I’m interested in discovering more about Murnong. We have 32 acres of native forest at Denver near Daylesford. We are restoring .


    1. Sounds really interesting Peter. Let me know when you are planning to be in Melbourne and out at Monash in Clayton (

      I’d be happy to meet you and show you around the garden and find our more about your project. There is a plant guide that you can print out via the website too, which helps when you are wandering around.

      There is no Murnong currently growing in the Aboriginal garden but the MECCARG – Merri Murnong group in the Merri Creek catchment area in Coburg has had some success propagating and cultivating the plant. May be worth getting in touch with them too. Cheers – Tess
