WEATHER - Nature's Forecasters - Plants

Updated on January 20, 2011

How Plants can predict the Weather ...


Some species of Cacti bloom and show signs of new growth in readiness for a wet period.


Crocus are commonly seen in gardens and bloom intermittently during Autumn, Winter and Spring.  In many parts of Australia, the Crocus will bloom a week or so prior to rain, regardless of the season.


If the seed-heads of dandelion are seen rising into the air, despite no noticeable wind, then bad weather is to be expected.

DATURA  (Angel’s Trumpets)

Datura does not have any particular flowering period, but rather, display blooms throughout the year.  When the plant stops blooming a wet period follows.


Many Eucalyptus trees display unseasonal growth prior to rain.

A species of Eucalyptus (Wild Apple) comes into a mass of buds and flowers prior to a drought breaking.

IPOMOEA  (Morning Glory)

If the day is going to be wet, Morning Glory flowers will not open in the morning.


If Mango trees have an exceptionally heavy covering of blossoms, a particularly severe cyclonic season can be expected.

Mango trees will often show intensely red new tips before heavy rainfall.


When a heavy, wet period is on the way, several species of Melaleuca are known to bloom out of season.

MURRAYA  (Mock Orange)

The ‘Mock Orange’ Murraya is an ornamental shrub that bears a profusion of sweetly scented blossoms several times through the year and usually after rain.  During a dry spell, if the ‘Mock Orange’ blooms the rain is sure to follow.


Throughout Australia, various plants with ‘lily-like’ flowers will bloom prior to rain.  Many will display colourful new growth, and even old trees will show a covering of bright, light green tips.  When this is seen during very dry periods it is an indicator that there are favourable weather changes ahead.

      Research has been done on how plants behave with weather changes and the like, and also knowledge handed down to others.

      "Weather Natures Forecasters-Plants"

      The hub is informtive, educative and suggestive.

      It tells that all knowledgable is God Almighty alone but He has not left His creations without guidance. There are the instrumenalities of the nature, the environment, the universe, the animals, the birds, the insects, the plant, the vegetations, the hevenly bodies, the inner and outer sensations of man himself. There may be many reasons for all this but one apparent reason is that man is to govern and goodly govern this earth as vice gerentof God and to prove his worth by excellent performance where by the dignity of mankind is established, rights are protected and duly and punctually paid. The favour of God are many and multiple on man which he is to use and utilize to offer thanks of God Almighty. All scientific researches are in fact lifting the vwil from the hidden treasures and the only fallacy that may cause damage to the whole achievement is to forget the real Creator of all. Hence Remembrance of Allah with every breath we in hale and exhale is necessary. The Holy Qur'an is full of knowledge and wisdom and appreciates thinking, rethinking and gaining all useful knowledge as a noble pursuit.

      The hub is excellent.
