If it was trunkless then it is pretty definitely X. concava, which is the common trunkless coastal species. There is a bit of X. australis (trunked) on Mandeni, so it could be around. And if you are in wet heathy areas, then X. resinosa is likely. In terms of appearance, they are all pretty similar, so habitat and trunked vs trunkless are the key features.

As for habitat it is growing next to the Pomaderris sp on Widgeram road and when I measured the scape the bottom of it was pretty close to the ground

Ok I'm happy to call it concava. Site sounds moist but not boggy, and boggy and heathy is what resinosa prefers.

Hi there,
I have 100+ Xanthorrea Concavas on my 8 hectare property at Bodalla. I'm finding it difficult to obtain information on propagation. Wondering if anyone here has alternative sites I could visit please?
Cheers - DebB

The Australian National Botanic Gardens in Canberrra might be an option
