They don’t call me flower

Some plan the future
-- stress and suffer --
Some live in the moment
-- even more so --
I cover the ground
turn my soft side to the clouds

C major has three tones

Some try to approach
-- hurts for a while --
Some try to fight
-- even longer time --
I sting in each direction
snake tooth shape

C minor has three tones

Some offer colours
-- no own desire --
Some offer scents
-- even for honey --
I throw my future to the wind
prepare your calamine

Urtica dioica has ninety tones
