Hemp
This canopy of trees isn't actually a canopy of trees at all. When you look closely, you see these trees are actually giant stalks of hemp.
Wow, these hemp plants are so big that they look like trees. But, despite their size they're still just hemp.

Who planted all this hemp? Your mama (ま) did.
Your mama knew that you were going to like hemp in the future, so she planted these hemp plants for you. What a great mama.
