Nectar source for Western Tiger and various insects
This wild oat grass has clusters of clumpy, hard ends, and weeping, thin stems. It covers a large area of Corona Heights.
This plant appears to be a common sorrel according to all of the descriptions, however the images I found online of a common sorrel appeared only similar to this plant, not identical. It has miniature red bulb-like flowers and thin leaves. The stem is thin but sturdy.

This was easy to spot. The distinct yellow flowers stemming from the weed-like leaves made the dandelion very apparent against the dry brush background. These were not too common in Corona Heights, but I did come across a few on my trek.
This plant had white bud-like flowers with deep purple ends. It also had leaves that split into two separate components. It grew in disorganized bunches along the grassy hills that ran along next to the trail in Corona Heights. I had trouble identifying the flower, for there were many other plants that fit my description when I researched my findings online.
This ivy took over a good portion of the rock walls located next to the trail winding up Corona Heights. It was identifiable by its dark-green color and its five-lobed leaves. It is a vigorous climbing shrub that seems to like rocky perches.
