Question
Dear Sir,

Can you please tell me how to know recognize a "petunia" and how to recognize an "impatience".  I am trying to see the difference  between these plants.  They both sort of look alike to me.  Most people can recognize these plants - I cannot.  I would really appreciate your help.

Thank you

Rich

Answer
Rich,
An easy way to remember it is that petunias have trumpet shaped flowers and impatiens have flowers that are made up of 5 individual, round petals.

Petunia flowers can be seen here: http://asteroid.cs.linfield.edu/~khubric/images/petunia.jpg  and Impatiens flowers can be seen here: http://www.types-of-flowers.org/pictures/impatiens2.jpg

I hope this helps!
