Taking the first letters of some columns. e.g. The second word of each line gives us SILK. Doing so for the third and fourth give SEED and COB. They are all words related to corn.
Corn is usually planted in large fields in rows/columns.
When corn is fully grown, you will see many green, erect stalks.
Because corn is grown close to each other, the fields end up being quite dense, so it is easy to get lost in them as you would a labyrinth. Corn has also been historically exotic. It wasn't until we bred it over generations for it to become a common source of food.
This might reference the data structure that is nodeless (not a tree) and keyless (not an array). One would be the stack. The devious behavior might be the action of popping items off the stack, and popping is what we do to corn to make popcorn.
How it relates to the title
Corn is also known as maize, which is a homophone for maze, so it's a "maze" in that sense.
