Rain smells so good
With distinct earthy flavour
Unsophisticated taste of beet
Petrichor in the air
When rain falls in a gasping land
Kids love to play with dewdrops
Taste and smell it
Actinobacteria’s disambiguation
Fluid that flows in the veins of Gods
The distinctive scent that comes
After a long warm dry spell
Scent of rain called Geosmin
Pearl rolling unto the edge
Overflowing with sentiments
Emotions overrated
Asked once more the scent of rain
Petrichor is literally petra [stone] + ichor, the divine blood. It is the earthy scent produced when rain falls on dry soil. Plants exude an oil during dry spells, which is absorbed by rocks and clay-based soils, and the rain causes the release of the oil and also another compound, geosmin, which is a metabolic by-product of certain Actinobacteria. And this is waht causes the distinctive odor after a rainfall! Sharon's poem combines the science with the sentiment, the pearl rolling over the edge.
