This listing is for Casuarina cunninghamiana otherwise known as She-Oak. 50 seeds. Native of Australia. Great as a windbreak or hedge or just something interesting/different in the garden. Germination may be helped along by a stratification treatment. I planted seeds in June and they did not germinate until October, so I’m not sure at this stage whether it was the heat that they required or the stratification. I’d encourage you to do your own research.
