I have about 30 black pines that I've collected from our property 12 months ago so with nothing to do I thought I would do a formal upright, styled after the huge old araucaria heterophylla that stand on the cliffs around Kiama harbour.
I'm thinking of doing 7 or 9 of these in this style for a group planting

I may have to collect another 20 or so ( we have thousands of them in all sizes ) and start experimenting!
