People admire plants, but we don’t easily relate to them. We don’t sympathize with a plant’s struggles, nor do we particularly identify with any one plant the way we might empathize with our pet dog or cat. Compare the range of words we have to describe such human experiences as fear, exhaustion, revulsion, joy and thirst with a mere handful for the most prominent conditions of plant life—growing, blooming, wilting, and a few others.
This distance isn’t surprising. Plants are different from us in basic ways. They can’t change their locations, they don’t have faces, and they don’t eat other organisms. We know they are alive, but they also seem alien.
I think the poverty of our understanding of plants contributes to our uncertainty about the meaning of our own lives. Humans are prone to feeling that being alive is either an exclusively human pleasure or a lonely human struggle. We lose touch easily with the reality that plants along with animals have been passing through the experiences of growing, struggling, fending off threats, and sometimes flourishing, for hundreds of millions of years and by the billions. We might feel more at home in our own skins if our imaginations could take in the lives of plants a little more readily.
Hope Jahren helps us do this. Lab Girl, her memoir, traces her life through the rigors of becoming an established research scientist and her workaholic triumphs and disappointments in labs and in the field. The bristling autobiographical chapters alternate with brief essays about how plants function and survive. It’s these plant chapters that most caught my attention. Here are excerpts:
No risk is more terrifying than that taken by the first root. A lucky root will eventually find water, but its first job is to anchor—to anchor an embryo and forever end its mobile phases, however passive that mobility was. Once the first root is extended, the plant will never again enjoy any hope (however feeble) of relocating to a place less cold, less, dry, less dangerous. Indeed, it will face frost, drought, and greedy jaws without any possibility of flight. ….The root grows down before the shoot grows up, and so there is no possibility for green tissue to make new food for several days or even weeks. Rooting exhausts the very last reserves of the seed. The gamble is everything, and losing means death. The odds are more than a million to one against success.
But when it wins, it wins big. If a root finds what it needs, it bulks into a taproot—an anchor that can swell and split bedrock, and move gallons of water daily for years. (52)
A cactus doesn’t live in the desert because it likes the desert; it lives there because the desert hasn’t killed it yet. Any plant you find growing in the desert will grow a lot better if you take it out of the desert. The desert is like a lot of lousy neighborhoods: nobody living there can afford to move…. A desert botanist is a rare scientist indeed and eventually becomes inured to the misery of her subjects. Personally, I don’t have the stomach to deal with such suffering day in and day out. (142)
Here’s my personal request to you: if you have any private land at all, plant one tree on it this year. If you’re renting a place with a yard, plant a tree in it and see if your landlord notices. If he does, insist to him that it was always there….
Once your baby tree is in the ground, check it daily, because the first three years are critical. Remember that you are your tree’s only friend in a hostile world. If you do own the land that it is planted on, create a savings account and put five dollars in it every month, so that when your tree gets sick between ages twenty and thirty (and it will), you can have a tree doctor over to cure it, instead of just cutting it down….
At the end of this exercise, you’ll have a tree and it will have you. You can measure it monthly and chart your own growth curve. Every day, you can look at your tree, watch what it does, and try to see the world from its perspective. Stretch your imagination until it hurts: what is your tree trying to do? What does it wish for? What does it care about? Make a guess. Say it out loud. (282)
Most people are more inclined to imagine what it is like to live on the moon than what it must be like for the tree in the backyard to brace for winter. We can’t know for sure how a plant experiences events, but we can, as she urges us, “stretch [our] imagination until it hurts.”
And then there’s “you’ll have a tree and it will have you.” Considering the world’s deteriorating environment, Jahren argues, if one tree can rely on you, that tree is well off. I would add that the benefit is mutual: we ourselves are better off if we can share and feel, even faintly, the life of any plant.
