I planted myrtle 2 years ago and it is just not spreading so I am moving on to Bugle or Ajuga. I am looking to cover a very large hill side- approx 45'x30' and I currently have 80 bugle plants to put in. I need to know how fast it grows so that I I know if I need one more flat.
So, how fast does Bugle spread? Am I only looking at a little spreading each year or is this going to take over quick like mint does? I am crossing my fingers for quick...
