Came across a little Osmunda fiber - what would YOU do with it?

[Orchid Whisperer]

While doing a little garage clean-out, I came across some Osmunda fiber in a plastic bag. Maybe a quart or two. It seems to be in good condition, even though it must be 10+ years old.

I know Osmunda is close to impossible to find these days, and is wicked expensive when you can find it.

Osmunda used to be the potting medium of choice decades ago. I would like to put this material to good use. I'm looking for suggestions - what would YOU use Osmunda for? Potting medium? Pads for mounted plants? Any particular types of plants you would use the Osmunda for?

I look forward to reading your suggestions.
