Comments on nostr are hard to follow, so Ill just reply to this wonderful idea: Fruit bearing trees like nuts and peaches, conifers are great because they create a natural wall for noise wind amd snow, sugar trees like maple, then family trees like tech and genetic histories.
I enjoy low time preference beings... bristlecone pines. Some are close to 4000 years old.
