On a trip up the coast with kids for sport... Stopped in at a nursery in Nambucca Heads, and surprised to see Phyllodium pulchellum plants for sale and they're loaded with seed pods
The most common rootstock used is P. caerulea, as W.C mentioned. It's a bastard of a plant to get rid of once it's invaded.

@withdrawl clinic sadly none sprouted for me, even with a heat mat to help along. I still have the container going just in case there is still hope
Thanks to your generous spirit!!
