I'm taking the liberty of cross posting Puma's post on the Potterne crop cricle looking like a lotus here, because i think the interpretation is an interesting, and hopeful one, whether it is correct remains to be seen.
I'd just add that, as for it also looking like a sunflower, i'm reminded of how the sunflower has been used as a symbol of Ukraine, and both it and Russia produce half of the world's seeds (and the shortage that was reported at the beginning of the conflict) despite the plant originating in the Americas.
Here's a few pictures of lotus flowers that i thought look similar to the above:
