I don't see why we need warm-blooded plants. I had spinach growing in my garden in 2020. Usually I pull up anything in the garden and till it but in fall 2020 I didn't. Spring 2021 and there was the spinach green as emerald. All through -20C, freezing rain, snow, just all around cold weather it was fine. edit: forgot to add frost in the ground probably down 60cm or 75cm so it's also affecting roots. Spinach is cold loving but I though it was amazing. Even more impressive than grass on a lawn which often is fescue, rye, bluegrass.
