Plant Kingdom Facts

Coast redwoods (Sequoia sempervirens) are the tallest trees on Earth. The tallest known specimen, named Hyperion, stands at over 380 feet (116 meters) in California.

Rafflesia arnoldii produces the largest individual flower, measuring up to 3 feet (1 meter) across and weighing up to 24 pounds. It is found in the rainforests of Southeast Asia.

Methuselah, a Great Basin bristlecone pine in California's White Mountains, is approximately 4,850 years old, making it one of the oldest known living organisms on Earth.

Plants absorb carbon dioxide (CO2) from the atmosphere during photosynthesis. They use sunlight energy to convert CO2 and water into glucose and oxygen.

Oak trees produce acorns. A single mature oak tree can produce tens of thousands of acorns in a good year, though only about one in 10,000 will grow into a new tree.

Bamboo is the fastest-growing plant on Earth. Some species can grow up to 35 inches (91 cm) per day under optimal conditions, which is nearly 1.5 inches per hour.

Chlorophyll is the green pigment in plants that absorbs light energy for photosynthesis. It absorbs red and blue light but reflects green light, giving plants their characteristic color.

The Venus flytrap is native only to a small area within a 75-mile radius around Wilmington, North Carolina, in the coastal Carolinas of the United States.

Pando, a grove of quaking aspen trees in Utah, is considered the world's largest living organism by mass and area. It is a single clonal colony connected by one massive root system, spanning about 106 acres.

Cinnamon comes from the inner bark of trees in the genus Cinnamomum. The bark is dried and rolled into the familiar cinnamon sticks, or ground into powder.

Trees communicate through underground fungal networks often called the 'Wood Wide Web.' Mycorrhizal fungi connect tree roots, allowing them to share nutrients, water, and chemical warning signals.

Saffron comes from the stigmas of the Crocus sativus flower. Each flower produces only three stigmas, and it takes about 75,000 flowers to produce one pound of saffron.

Red romaine lettuce was the first food crop successfully grown and eaten in space aboard the International Space Station in 2015 as part of NASA's Veggie experiment.

In autumn, trees stop producing chlorophyll, which breaks down and fades away. This reveals yellow and orange pigments (carotenoids) that were always present but masked by the green chlorophyll.

The snake plant (Sansevieria) is extremely resilient and can survive weeks without water. It stores water in its thick leaves and can tolerate low light, neglect, and a wide range of temperatures.
