Howdy!

Carex appressa is a plant that gets talked about a lot in Australia with respect to bioretention systems so it’s definitely worth knowing a bit about it. The reason it gets talked about a lot is that it has been researched a lot and it performs really well at keeping the filter media nice and porous and it enhances the ability of systems it is planted in to remove nitrogen.

Now that doesn’t mean that it’s the best plant for either of these tasks. There are many other plants that haven’t been tested at all. Some of them might perform better. We just don’t know.

What you should know though is that Carex appressa can be a little fickle compared to something like Lomandra. In this episode we explore all of this.

I hope that you enjoy.
