Plants That Predict the Weather

Learn What Signs to Look for in These Plants with Weather-predicting Abilities

By understanding the subtle cues given by these plants, you can become more in tune with nature and perhaps even impress your friends with your newfound.

When it comes to predicting the weather, most of us rely on meteorological forecasts and apps. But did you know that nature has its own set of weather indicators? That's right; certain plants can give us clues about upcoming weather conditions, offering you a technology-free, natural way to anticipate what Mother Nature has in store.

Why Plants Are Reliable Weather Indicators

Plants have evolved over millions of years to adapt to their environment, including the weather. Their survival often depends on their ability to respond to changes in humidity, temperature, and other climatic conditions. As a result, some of these evolved plants can read these natural signs as a form of weather prediction.

Plants That Predict the Weather

dandelions in rain


Dandelions are more than pesky weeds; they are also natural barometers. The flowers close when bad weather is approaching, serving as a reliable indicator of impending rain. This is because the plant is sensitive to humidity and changes in atmospheric pressure.


Pinecones are another excellent example of nature's weather forecasting. The scales of a pinecone will close when it's about to rain and open when the weather is clear. This is a survival mechanism to protect the seeds from getting wet, which could lead to rot.

Tulip Flowers

Tulips are not only beautiful; they are also weather-sensitive. Tulip bulbs tend to contract and expand with changes in humidity, often closing before a storm hits. Gardeners have long observed this phenomenon and used it as a natural clue to changing weather.

scarlet pimpernel flowering plant

Scarlet Pimpernel (Anagallis arvensis)

Commonly known as the shepherd's weather glass, poor man’s weather glass, or shepherd's clock, the scarlet pimpernel is a small flowering plant that closes its petals in response to atmospheric changes, particularly before rain. It's a popular subject in folklore and has been used for centuries as a natural weather predictor.

sensitive plant

Mimosa Pudica

Commonly known as the sensitive plant, Mimosa pudica, a perennial flowering plant of the pea/legume family, is famous for its rapid leaf movement. While it primarily closes its leaves in response to touch, it also reacts to sudden changes in light and temperature, making it a useful indicator of weather changes.

How to Use Plants for Weather Prediction

Observe Patterns: Spend some time observing these plants and their behavior in different weather conditions.

Take Notes: Keep a weather journal, noting down the plant's behavior alongside the actual weather conditions.

Compare: After a few weeks, compare your notes to see if the plants' behavior consistently correlates with specific weather patterns.

Trust but Verify: While plants can be reliable indicators, they should not replace professional weather forecasts, especially in severe weather conditions.

Plants are so much more than decorative elements or food sources; they are intricate organisms that interact with their environment in complex ways. By understanding how certain plants respond to weather conditions, we can gain valuable insights into the natural world and even get a heads-up on what the weather will do next. So the next time you step into your garden or go for a hike, pay attention to the plants around you; they might just be trying to tell you something.
