No matter how many times I have tried to kill them they still thrived. 

Admitting defeat I’ve left them as is and went around them with my pebbles and stones.

What can one do ? 

Don’t underestimate their pathetic sight .  They actually flowered one year and gave me beautiful purple flowers.

As for this bush it’s gotten bigger. 

As for me as soon as I accepted the situation  my outlook was different.

Moral of the story:

If unhappy make changes. If can’t make changes then learn to accept 😂
