General solution by Matthew Arcus.


Lemon juice
May be yellow
Or may be green
It can be sweet or sour
As your life can be
It grows like
Little suns
You can drink it
As lemonade
You find it on your table
Or as a vegetable
Good for coughs
And for flues
It can be acid
Fresh and juicy
Lemon is always a beauty
