Ok guys, I was just browsing and came across the American Harts tongue fern. There has been a plant at my work in a pot on a windowsill for as long as I can remember. Which DOESNT mean it's been there really long, I just started noticing it.
It looks identical almost to the endangered fern.
Are there any look alikes. I'd like to be wrong.
And if it is. How should I approach this?
You can't even buy them..
