Quantitative Trait

What: I'm not sure what type of plant this is but it is a good example of how quantitative traits vary from plant to plant.
Where: I found these flowers outside of the dentist office by my house.
So: These plants have a clear difference in many different quantitative traits. The trait I am trying to show is the number of flowers per plant. The number of flowers on these plants vary due to the environment they are in.
