>>23064464The problen with planting mint in the ground besides invasiveness is that the varigated varieties like pineapple, chocolate, and orange mint will revert back to the non varigated variety in a year or two. It will also strangle itself potentially, depending on conditions and variety.
Pineapple mint is amazing.
Best thing to do with mint is plant it in a 3-5 gallon pot, keep it pruned to reduce need for watering, and repot it/divide/ or clone it every 6 months in a warm climate, once a year if colder, and replace it with a fresh cutting when it reverts.
Keep in mind Oregano and other herbs are in the mind family and are equally invasive in the right conditions.
For a herb lawn I suggest creeping thyme.
Its particularly nice planted in cracks between rocks or pavers in pathways and patios. Very hardy and drought tolerant, spreads and grows similar to grass, is mowable, and freshens up and disinfects your shoes when you walk on it.
Thymol, the compound responsible for thyme flavor, is the main active incredient in listerine. Very powerful antiseptic.
