Chelle, I've noted that too about mint. The best compost I've ever used had lots of mint in it- the garden responded as though I had fertilized. Mints also deter rodents, and I've found Lilies growing with the mints tend to remain safe from voles.
"...and don't think the garden loses its ecstasy in winter. It's quiet, but the roots are down there riotous." Rumi
