Many plants predict the weather by their behavior and can therefore be called living barometers. In central Russia, there are more than 400 species of such plants.



It is enough to look at the clover to see that this plant senses the approach of bad weather. Before it starts to rain, the clover pulls the cap of its inflorescence closer, folds the leaves, the stem of the flower bends down and the inflorescence droops. This plant is very common, therefore it is a reliable barometer.

Just like clover, or even more so, dandelion is common. It is found everywhere, as it is unpretentious and hardy. Its flowers can be found in the forest, boulevards, vacant lots and meadows. This plant is also a barometer, and no matter how familiar its white and yellow flowers are, it is worth looking at them in order to determine the weather. A faded dandelion, white in color, easily spreads its fluff everywhere in dry weather, and if rain is possible, even a strong wind cannot blow off the fluff. In anticipation of bad weather, the dandelion folds its inflorescence. Its yellow flowers sometimes do not open in the morning, anticipating bad weather.

Another barometer grows in coniferous forests. The leaves of the sorrel also consist of three lobes and are similar in appearance to clover, but significant differences are visible up close. Oxalis can cover large areas, and blooms in small white single flowers, similar to violets and very short-lived. Both flowers and leaves are folded before the rain, pressed against the petals.

In good weather, the flowers of the tricolor violet are fully open. And before the rain, they droop and close, so that they become completely invisible. Often, anticipating rain and bad weather, the inflorescences of mallow and marigold close. Among aquatic plants, a good barometer is the water lily, which closes its flower before rain and goes under the water.

Before the rain, acacia begins to smell intense and exude nectar. So a sure sign of approaching bad weather is a lot of insects in its colors. It also reacts to changes in pressure and humidity before rain and honeysuckle, starting to smell much stronger.


The leaves of carrots, which are grown in many vegetable gardens, droop before the rain so that the rain does not break them. Bone leaves twist in different directions, and this is worth taking a closer look at. Before good weather, the leaves curl down, and if the leaf is untwisted or bent up, this is a sure sign of bad weather, the approach of which the stone bone often feels in a few hours.

A fern is similar in this to a drupe, and its vai leaves are also curled downward before good weather, and straighten before bad weather.
