There has been some confusion over these varieties and because yours has a blue/green colour and C. hildmannianus and its subspecies are grey/green I still think yours is C. repandus. The 2 pieces you sent Colleen are both going OK the piece I got from Colleen rotted on the top. I cut that off and now have 2 new branches and growing well.
Photo is C. hildmannianus growing on the roadside between Barmera & Glossop.
