Signs and scents of autumn

Rain…..the word evokes such mixed emotions.  Ask a Melburnian what they think of the rain and they will wrinkle their noses in discomfort or disgust.

But in the country, especially with a climate where hot dry spells are more protracted, the sound and smell of rain is superb.

We can smell rain approaching, a phenomenon that is due to downdrafts of the ozone and the rain falling on dry surfaces, releasing smells from plants and soil. 

The term Petrichor is given to the earthy scent released by rain after dry spells. 

In Australia the smell is especially cleansing and refreshing due the release of eucalyptus oils from the gum trees.  But in the city, we mostly smell the odours of asphalt and dust.

Recovery after the rain here is astounding.  The dry bushland is glistening with moisture and with a renewed food supply, the local wallabies and marauding deer have stopped jumping the fence to ravage the garden. 

In the exhausted garden, the recent rain has brought about immediate regeneration.   The brown patches of so-called  ‘lawn’ are now bright green.

The deciduous trees that had dropped many of their leaves in order to survive, now display an intense Autumn colour.

With the rain, the trees and blooming perennials have brought a dry, tired garden back to life.
