Pic 1: The mini pond or possibly bog bed. It's empty of water, but lots of weeds growing out of it.
Pic 2: Another picture of the mini pond.
Pic 3: A view of the tree of heaven saplings that are growing from the beds.
Pic 4: An unknown plant/small shrub yet to be identified.
Pic 5: An unknown plant...it's gotta be an herb...if I pick the leaves and crush them they smell like lemon. Possibly a species of thyme?
