Plants may look quiet, but beneath the surface, they are some of the most surprising organisms on Earth. from underground root systems that stretch over continents to flowers that generate heat to trees that are older than societies themselves, the plant kingdom is full of mind-blowing surprises.


  • Plants are Constantly Moving and Responding

    Plant roots can grow deeper than many buildings are tall

    The roots of an alfalfa plant can stretch up to forty feet in search of moisture in the ground.[8]
  • A single rye plant produces enough root hairs to stretch pole-to-pole

    If they were laid out end-to-end, the root hairs growing on a single rye plant would cover almost the entire distance from the North to the South Pole.[8]
  • Bamboo can grow nearly 3 feet in a single day

    It's the fastest-growing plant on Earth.[10]
  • Plant roots change their biology when they find nutrients

    There are two different types of cells that in the roots of a plant: the cells that allow the roots to grow die when a source of nourishment is encountered, and are replaced by a different type of cell that is able to dissolve mineral salts and take in what remains.[8]
  • Leaves "sweat" just like humans do

    The leaves of a sunflower "sweat" out as much water in a single day as an average human male does.[8]
  • Vine tendrils rotate continuously while searching for support

    It takes 67 minutes for the tendril of a vine to sweep a full circle in search of something to wrap itself around.[8]
  • Climbing plants grow toward nearby objects without touching them

    Climbing plants will always mysteriously grow towards any nearby poles, leading some to speculate that plants have an ability to "see" objects in some way.[8]
  • Plants Doing Things You Don't Expect

    A sunflower isn't one flower at all

    The head of a sunflower is actually made up of hundreds of tiny flowers called florets.[10]
  • This plant moves when you touch it

    The Mimosa pudica plant can sense when an unwanted insect is crawling up its stem and will roll up its leaves in response.[8]
  • Plants do not speak, but their silence is alive with change.

  • Alpine flowers create their own heat

    Alpine flowers sense when spring is coming and create their own heat to melt any snow above them in order to start growing.[8]
  • The oldest plant on Earth is 100,000-year-old

    It's a massive seagrass colony growing off the coast of Spain.[9]
  • Ferns and mosses reproduce without seeds

    Unlike many other plants, which reproduce using seeds, ferns and mosses reproduce through spores.[7]
  • Some flowers smell like rotting flesh

    The "titan arum" flower can reach up to fifteen feet tall, and is also called the "corpse flower" due to its smelling like rotten meat.[10]
  • Some plants eat animals

    There are over 500 different types of plants that eat insect and/or animal meat.[8]
  • The largest leaves on Earth belong to the raffia plant

    The leaves of the raffia palm tree are the largest in the world and can grow up to 82 feet long and 10 feet wide.[7]
  • Trees Are Older than Civilization

    There are around 60,000 different species of trees in the world.

    While this number may sound large, it is far smaller than most people expect. Out of the roughly known plant species, only about 15% are trees. Trees may be visually powerful, but they are not biological dominant.[7]
  • The clearest way into the Universe is through a forest wilderness.

    - John Muir

  • Some types of conifer trees can grow up to 150 feet tall.

    This matters because tall conifers store massive amounts of carbon, create unique ecosystems high in their canopies, influence local climate and rainfall, and support species that live nowhere else.[7]
  • What is a tree?

    A tree is defined by botanists as a shrub which grows taller than other shrubs and has a stem that doesn't receded in winter months.[7]
  • Beautiful trees
    Plants endow our world with beauty and life

    The bark on a tree's trunk is a dead outer skin that protects the living trunk from the elements.[7]
  • Some of the world's oldest trees aren't individual trees at all

    The oldest trees in the world are an 80,000-year-old colony of quaking aspens in Utah. It has loved so long because it clones itself.[9]
  • Plants that Changed Human History

    Holland's tulip obsession

    A tulip craze in Holland during the 1630s, and one of the first asset bubbles, caused such a spike in the price of tulip bulbs that the Dutch economy temporarily crashed.[10]

  • Interesting Plant stories
    How could something hateful taste so delicious?

  • Plants are the core of human civilization

    Human agriculture, the growing of plants for food and other needs, began roughly 12,000 years ago. Without agriculture, large cities would not exist, written language, trade, and government systems might not have developed, and many modern foods wouldn't exist at all.[6]
  • Vanilla plant facts
    Vanilla pods are quite expensive at market
  • Vanilla comes from orchids, not beans

    Vanilla "beans" are actually pods of a strain of orchid, and are more closely related to corn than green beans.[10]
  • Lemon trees don't exist in the wild

    Lemon trees are the product of human hybridization, and do not grow in the wild.[7]
  • Cranberries float in water because of small air pockets inside the berries.

    Floating helps cranberries spread their seeds over water, avoid sinking into oxygen poor mud, and survive seasonal floods.[10]
  • Rare, Beautiful, and Dangerous Plants

    Some houseplants sell for thousands of dollars today

    Some of the priciest house plants you can purchase include the philodendron pink princess, the variegated monstera, and bonsai trees.[2]

    An orchid made in a scientific lab, the "Shenzen Nongke Orchid," sold in 2005 for $224,000, making it the highest recorded price for a houseplant.[2]
  • Bonsai Tree
    Bonsai trees are living art-forms
  • There are bonsai trees that are so small they could fit in the palm of a human hand.
