Are they weeds or some kinds or my wildflower plants?
I have sown native plant seeds and wildflower seeds in Spring and very early fall. I did not notice the two kinds of plants until their reaching to half the sizes as they are now. They have grown so fast. I don't believe that they are two kinds of my wildflower plants. They are probably weeds. However, why had they not showed up before I sowed wildflower seeds? They have never been anywhere either. They just grow up at the exact spots where I sowed the seeds. They confuse me. Please check the pictures to see if they are weeds (I uploaded 2 pictures for each type of plant for better details). The leaves of the first type plant look like philodendron's, yet it bears vines close to the flower parts.
The second type is below:
