I found all of these plants in inland San Diego, California. I would be very grateful if anyone could tell me what these plants are. Additional information about each of the plants is provided below if it helps with identification. Plant 1: Grows in large numbers, and can be found almost anywhere where there is lots of sun. Dying/old plants have black flowers and brown stems. Typically around 1 meter in height. Plant 2: Also grows in large numbers, and found where there is lots of sun. Mature plants range from 1 - 2 meters in height. Plant 3: Much less common than plants 1 & 2. Grows where there is slightly more shade, and is typically not found farther than 10 meters from a water source. Average height is 0.3 meters. Pictures are provided, if anyone needs more specific pictures, I'm happy to provide them.
