The Bible's interest in the spirituality of grain is provocative, but I wonder if you've noticed the regular spiritual imagery of trees that makes them seem as if they are divine beings. This is explicit in Judges 9:8-9--or Mark 8:24.

In 1 Enoch 24 there's a curious scene where Enoch is traveling through Heaven and is entranced by a tree. I'll paste it below.

•

The seventh mountain (was) in the middle of these, and it rose above them in height, like[65] the seat of a throne. And fragrant[66] trees encircled it. 4/ Among them was a tree such as I had never smelled, and among them was no other like it.

It had a fragrance sweeter smelling than all spices, and its leaves and its blossom and the tree[68] never wither. Its fruit is beautiful, like dates of the palm trees. 5 Then I said, “How beautiful is this tree and fragrant,[69] and its leaves are lovely, and its blossoms[70] are lovely to look at.” 6 Then Michael answered me, one of the holy angels who was with me and was their leader, 25:1/ and he said to me, “Enoch, why do you inquire and why do you marvel about the fragrance of this tree, and why do you wish to learn the truth?” 25:2 Then I answered him—I, Enoch—and said, “Concerning all things I wish to know, but especially concerning this tree.”
