Anomaly
We left Animal Crossing for over a month and then decided to come back, and noticed "oh huh, the weeds look pretty cool". Cut to spending today purposefully planting weeds around the island to make it look good.
I think it gives a more wild/natural feel, and it makes the terrain look very cool and honestly kind of pretty. It also fills the island in a more subtle way than filling it with flowers, and there's no risk of trampling them, and look awesome combined with flowers. You just need to be careful planting them around fruit trees.
I don't really like how having weeds knocks down your island rating, but hey they still look neat.
