I tried this several times in several locations and it never did well, eventually dying.

Wonderfully textured purple gray leaves, looks great all season long. Adapts to most soil types but prefers fertile, sharply drained soil. Tolerates drought but looks better when watered regularly. Can withstand light foot traffic so ideal as a ground cover. Good plant for terrariums, too.

Will handle some foot traffic. Can be invasive in some areas. Spreads quickly by underground runners. Likes full shade in warmer climates.
