i was given a Xanthorrhoea, it has a tag from Queensland, maybe it's Xanthorrhoea semiplana ssp. semiplana. (I am in Adelaide) It flowered over summer on a long stork. I've been told there is a very low survival rate for nursery-purchased plants. I wanted to place it in the garden in a well drained and sunny position. it's currently in a 300 mm pot. When and how should i go about transplanting it into the garden or should i keep it in the pot. Thanks
I found these links that provide planting information.
