Tall, skinny trees with branches extending almost vertically into the air. Observed at Discovery Park. Sorry I couldn't rotate the picture.
Field bindweed also common known as "morning glory" spotted at the Washington Park Arboretum. Though it may be aesthetically pleasing the morning glory is a very common invasive species in many places.
A patch of red clover on the less dense side of my location at Discovery park for our final. Red clovers do have those distinctive dark pink flower but there was none with this batch of red clover.
In the less dense areas of my location at Discovery park it consisted of mostly of various grass type such as the quack grass, and also fields covered with clovers as well. Apologies, I don't know why my photos are sideways.
A few big leaf maples around the location of my final at Discovery park. About average height and I also noted that the big leaf maples were only found on one side of my location, heavily covered with sword ferns while the other side was more of an open area with very few trees and mainly grass.
