The thread in the link above discussed moving a few different cypress into a group plating. This photo below is the end result and it seems to be travelling ok. I said at the time that I wish I had a tree to fill that gap on the right...but I did not. This morning, I had reason to travel to Hawthorn and I visited Lindsay's Bonsai Farm for the first time in a few years. I was about to walk out and I noticed a Boulevard Cypress - looking sad, unpotted (i.e - not even in a plastic pot, simply sitting near a potting bench, looking like a tree-orphan; forgotten to be re-potted.) Hmmmm ...
look at that shape... my forest!! 
I enquired and was happy with a very reasonable price. It needed to be, it's not like it was a well kept specimen and there's some risk. 
Anyway, I took the risk and off home I came. Here's the tree as it was - no pot.
..but ...look at this back budding, which is a not easy on this species, so there is some health. I think.
and here is that plant roughly positioned .. see how it will fill the gap when I replant the group on a couple of year's time. I love how it fills the gap. It was meant to be. 
Anyway, in the meantime, I have liberated the poor orphan tree. A light root prune (well a 1/4 removed from the base), teased out the roots and replanted into a rescue pot. Here 'tis.
I like the story developing here. Its a shared project for sure. Trees have been purchased from 3 Victorian bonsai nurseries - Bonsai Sensation, Bonsai Art and now Bonsai Farm. The larger trees have been rescued .... to the extent that the trees from Sensation were pot bound on sale and today's from the Farm was about the same. The Art series are the complimentary seedlings and younger plants. So ... let's see how it turns out over the coming years. Hopefully it works. 
) but I am learning by trying and even this trim is a mile ahead of anything I could have attempted even a year ago. Thanks to Ray for giving me some practical advice at a YVBS BBQ last weekend too.
... sooo.. the group will remain as is.
