Intuitively this makes sense when you consider old-growth trees that have survived for hundreds of years. It's not difficult to revere those old trees in some way. The broader ethical implications are difficult though. If you have a sapling of the same species, then surely it should be given the same reverence since it could well be an old tree in the distant future. So perhaps there is a continuum of rights based on expected life-time of a plant? What is the natural lifespan of a crop plant, or a legume?

There is a decent fraction of vegetarians and vegans who eventually land on Antinatalism, though their focus is usually based on the sentience of human and non-human animals that have a capacity for suffering, not just life. However, perhaps sentience is still the crux of this concern. If an old-growth tree is felled due to an earthquake, it is still tragic but there wasn't an intentional decision responsible for its death. So maybe Antinatalism also resolves this dilemma indirectly.
