This is my first puzzle, so please be gentle! Came up with the idea on a drive home and thought it was neat, so I'd like to share it and see if it's as tricky as I hoped.
Originally I planted flowers for you to digest
Later I decided to colour in your stomach instead
I often prevail on the battlefield
But I've rarely carried my team to victory.
What am I?
The answer is an abstract noun.
Lines 1 and 2 are quite closely related.
Look between the incisor and premolar. Nowhere will Muriel show you a brave one.
Edit: I've added a bit to the cryptic hint which should make the answer clearer.
