As a kid, Chris Thorogood loved looking at unusual plants in books. One of his favorites was Rafflesia (ruh-FLEE-zhuh). This group of plants produces large red, spongy petals. Some species have flowers that are three feet wide. The blooms reek like rotting meat! This stinky scent attracts flies, which then help spread the flower’s pollen. That’s why this plant’s nickname is the corpse flower.

“I thought, ‘Wow, I would love to set eyes on a plant that magnificent one day,’” says Thorogood.

The Rafflesia arnoldii flower smells like rotting meat! It measures up to 1 meter (1 yard) across. What else is that length? Grab a meterstick or yardstick and measure!

Today he fulfills that dream every day! He works as a botanist at the University of Oxford Botanic Garden in England. Thorogood travels throughout Southeastern Asia to study rare and unusual plants—including Rafflesia. He also draws the plants he studies for books, magazines, and research papers. Thorogood spoke with SuperSTEM about why plants are incredible and important.

Now he fulfills that dream every day! He’s a botanist. He works at the University of Oxford Botanic Garden. It’s in England. Thorogood travels around Southeastern Asia. He studies rare and unusual plants there. That includes Rafflesia. He also draws the plants he studies. His pictures end up in books, magazines, and research papers. Thorogood spoke with SuperSTEM. He explains why plants are amazing and important.

Why should people care about plants?

We tend to think of “life” as animal life, with plants as a sort of green backdrop. But we have to remember that plants not only create the habitat where animals live—plants are alive too! They also create the air that we breathe. This happens through a process called photosynthesis. Plants take in carbon dioxide, water, and sunlight to produce sugar and oxygen. Plants are essential for life to exist! We also use plants to make clothing, food, and medicines.

Right now, many plants are in trouble. More than two in five plant species are in danger of dying out. It’s important to study plants because we can’t properly care for the species we don’t know about.

How do you find plants to study in the wild?

Kuya Willis, a Banao guide, helped Thorogood find rare flowers in the Philippines.

I love that my job takes me to places many people don’t get to go. I’ve visited some of the most faraway and isolated parts of the Philippines, Indonesia, Sumatra, and Borneo.

The flowers I study can be difficult to find. I often rely on local people who live near the areas where they grow. They know these plants very well.

In 2022, I set out to find a particular species of corpse flower in the Philippines. I stayed with the Banao tribe, an Indigenous community. They took me deep into the forest, trekking for days through very difficult landscape. When we finally found the flower, it brought tears to my eyes to see something so extraordinary. I’m told that I was the first person from outside of the Philippines ever to see this species.

How do you study plants?

I do all kinds of experiments to learn about plants and how they survive. Right now, I’m studying pitcher plants. They’re fascinating! These carnivorous plants have leafy tubes shaped like pitchers. Insects slide off the pitcher’s slippery rim and tumble into the plant. The insects get digested in a pool of liquid, feeding the plant.

I’m working to find out if the shape of a pitcher affects the type of insect that gets caught. Mathematicians at Oxford used computer programs to test how insects might fall into pitchers of different shapes and sizes. We found that the pitchers that flare out more are especially good at catching walking insects such as ants.

Why do you paint the plants you find?

Plant scientist Chris Thorogood paints the plants he observes, like this corpse flower!

When I see an incredible plant on my trips, I feel the need to document it through art. I take a lot of photographs, observe the plant very closely, and draw a lot of sketches. At home, I put them all out in front of me for inspiration. Then I paint the plant!

Illustrations have always been important to botanists. Before photography, scientists included illustrations with their descriptions of new species in research journals. Illustrations can show all the tiny details of a plant very clearly and precisely in a way that photos cannot—similar to diagrams. Illustrations are still used today. Drawings and paintings of plants are also things of beauty!

If a kid wants to study plants, where should they start?

There’s fascinating nature everywhere you look—you don’t need to grow carnivorous plants or go to the jungle. Go on an outdoor walk or take a trip to a park. Whether it’s on a tree or under a stone, you’ll find incredible plants if you look closely.

Step-by-Step Lesson Plan

1. PREPARE TO READ (15 minutes)
Watch a video about plants and discuss the importance of photosynthesis.

  • Ask students to share where they have seen plants today—for example, at home, on the way to school, or as part of a meal. What did they notice about these plants? What do they know about them? Have students raise a hand if they would agree that plants are important in their lives. Record the tally on the board.
  • Play the video “Powerful Plants.” Pause after the description of photosynthesis (1:28) and complete this sentence together: “During photosynthesis, plants use the sun’s energy to combine _____ and _____, making _____ and _____.” (carbon dioxide and water; sugar and oxygen) After viewing, ask students to support or refute this statement: “Life on Earth depends on plants.” (e.g., Plants provide oxygen that animals need to breathe.) Ask students to vote again whether plants are important in their lives. Did the count change? Why or why not? Discuss their thinking.

2. READ AND Evaluate (15 minutes)
Read the article and synthesize information about a career in botany.

  • Preview the article and discuss the STEM vocabulary (p. 28). Read the article aloud, pausing to highlight the key details that show what Chris Thorogood does and what knowledge he needs for his job as a botanist.
  • After reading, discuss what students think would be most interesting about this job. What might be challenging?

3. RESPOND TO READING (30 minutes)
Think like a scientist by observing, measuring, and sketching a plant.

  • In advance, review the Observe and Draw a Plant activity. It can be done either outdoors or indoors with potted houseplants or herbs. Discuss Thorogood’s process for drawing plants. Then give students a few minutes to use colored pencils to make different shades and tints of green, by pressing hard or lightly or by mixing colors.
  • Distribute and preview the activity with the class. Discuss how to measure or estimate a plant’s height. (For example, determine the highest point on the plant and measure from the spot on the ground directly below it.) Then have students choose a plant to observe. Encourage them to make their observations as detailed as possible. After students finish, have them share their completed drawing with a partner. Then come back together and discuss the concluding questions as a class. If desired, students’ work can be posted, along with the article, to make a bulletin board display.
