Below are some typical bog plants for this part of the world.
Dianella longifolia, the Pale Flax-Lily, which has beautiful blue berries:
Isolepsis nodosa, the Knobby Club-Rush, for the margins:
Mazus pumilio, Swamp Mazus, is a ground-cover with pretty blue flowers a bit like snapdragons:
And then there's the Bracelet Honey-Myrtle, Melalauca armillaris. It's not from my area, really, but the endemic Melalaucas are unsuitable for this position. I need something small, which will take on a tree-shape rather than a shrub-shape, and not scratch people. I'm hoping the position is not too wet as M. armillaris tends to be found in heathlands in high rainfall areas, not bogs. I've built it up a bit but am hoping it will tend to soak up water like other Melaleucas do.
I put a Dianella at each corner and the Melaleuca is on the hillock in the foreground.
The rushes are planted notionally around the edges of my pond, but it had been raining so they are actually in the water at the moment.
I have recycled some concrete edging in the hope that the lower Dianellas won't be washed away.
Another view, with long shadows cast across the pond.
I love the shadows cast on the wall by my Shasta daisies too.
