Background:
- The magnificence of a flower, such as the rose in the photograph below, can be as captivating as a majestic mountain. Many photographers over the years, both amateur and professional, have attempted to capture their beauty on film.
From small marigolds and daffodils...
to large magnolia trees...
...flowers are incredible creations engineered with a beauty rarely matched in nature.
- In this exercise, we will focus on Irises. Irises come in all sizes and colors, and are truly a work of art. The irises in the following photographs are from Schreiner's Iris Gardens and were grown on Staten Island, NY.
At the Schreiner's web site you can look up the names of these irises.
- In the exercises below, we will focus on irises to learn more about plants and photography. Before we begin, go to the web sites listed below to read and learn more about irises.

Based on the photos you have observed at these web sites, answer the following questions, and submit your answers to your instructor via email.
- Of the web sites you visited, which had the best photos of irises? Support your answer.
- How do the iris photos in this exercise compare to those at the sites you just visited?
- If you were writing a botany text book, and you wanted to include photos of irises, from which of the web sites would you choose? Why?
- Rhizomes are stems that grow underground. Irises contain rhizomes. Explore the chemistry of rhizomes by performing the Chemistry of Rhizomes Experiment.
Return to this page to submit your results to your instructor via email.
- This experiment will provide you with another opportunity to work with irises. Go to the
Virtual Clemson Irises
web site for experiments on planting, growing and propagating irises. Carry out the experiments and submit your results to your instructor via email.
- You have studied may photographs of flowers in this exercise.
Now it's your turn. With your camera and film, take a roll of
pictures of as many different flowers as you can find. Compare
your photos with those of others completing this exercise. Who
has the best photos? Why? Submit your work to your instructor,
preferably via digital scanning and email.
