Bog Garden Planted

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.

Bog Garden Construction Started

There has been more rain since my last post and of course many more activities, so I only managed to pop out to start on the bog garden today.

I dug out a shallow circle in the middle of the triangle today, but there is still so much standing water that only the top edge is visible. I removed some more concrete from it and perhaps the drainage will improve now it's gone.

My plan is to plant each corner with sedge to provide a marker, so nobody walks into it by mistake, and a small shrub in the uphill corner (species undecided as yet). The Sprig has requested edible plants so I'm considering water chestnuts and mint in addition to native plants.

I am also considering building a small wall on the far side so that less driveway runoff enters the area. This bed has been waterlogged for two months, after all. Didn't smell the best when I was digging it up.

I've been digging elsewhere in the garden as well.

This grille is one of the entry points to our vast retention pit, where runoff from our driveway, patio and garage roof collects. Note that the water is very high and the soil is not level with the top of the grille, so we've had overflow around the shaft. This isn't much fun to step in by mistake, and the unevenness of the ground is rather dangerous. I've now made the area surrounding the grille level. There are plenty of uneven areas in the back yard for me to dig up for fill. At the moment the soil is soft enough and the weather cool enough for it not to be a great chore. I had not expected to do this work until autumn.
