Old Doormat Wildflower Bed

Okay, you won't quite get the mass you see in the photo above but I have a plan for the spring.
We have a doormat that is ready for the scrap heap, I was looking for how to dispose of it, I was pretty sure I could compost it as it doesn't have a rubber back and it seems to be made of natural fibres.
It turns out these fibres are coir which is the hairy stuff from the outside of a coconut.

Step 1: Coir

As I said coir is the hairy fibres from coconuts. My research tells me that it is very good at obsorbing and retaining water. It breaks down in the composter or in a wormery.

Step 2: The Plan

Last year we bought a pack of Irish wildflower seeds, it was about €10 for a 1.5kg bag. I still have quite a few left. I'm a bit late this year but in the spring I plan on rubbing the seeds down into the matter and placing it I a damp corner of our front garden (it's a concrete driveway and a bit tight for 2 cars + flowerpots).
The hope is that the damp mat germinates the seeds and I get a little wildflower corner that will ultimately consume the mat, while giving us something nice to look at in the front garden. I will hopefully have some nice photos to add to this ible come late spring!
