Are there non-green lawn/ turf grasses?

Not to the best of my knowledge

Not grass thou, unless you dont water it, browns a colour...

The answer to this will not deviate with me either. No.

I have to say that if there were such things as blue, red, white or yellow grass, wouldn't you have seen it by now?! It would make front page news.

What about the grass that grows on sports pitches - magic stuff that appears to be 3D and usually advertises a product (lol). Seriously though, anyone who can get grass to grow in rainbow colours would become a millionaire overnight.

Astro turf?

If grass did grow in rainbow colours, I would grass over all my flowerbeds and have pschedelic swirls and patterns instead. It would be the end of gardening as we know it !!!!!

Just to be clear there 'are' grasses that are not green - but, they are not lawn grass!

You're absolutely right, James, many plants do not have green leaves - there's grey, bluey green, brown, purple, red, yellow, yellow/green, white and green - but, as Moon grower says, not a one is a plant you can use for a lawn - they cannot be walked on regularly, and they cannot be mown.

Just to clarify my former answer too, I was of course referring to grasses used for turf/lawns. I am familiar with glaucus, golden, copper and red leaves grasses and sedges. I should be as we sell enough of them at the nursery where I work. None are suitable though for lawns as Bamboo says.
