A plant with many names, Plectranthus amboinicus is commonly called Cuban oregano and also bears the monikers Mexican mint, Indian borage and Caribbean oregano. This evergreen perennial works well in mixed beds and mass plantings and as a ground-cover. Its edible, fragrant, rounded leaves bear a terminal point, serrated margins and a soft pubescence. Cuban oregano produces trumpet-shaped, lavender, pink or white flowers. Hardy in U.S. Department of Agriculture plant hardiness zones 10 through 11, the plant thrives in full to partial sunlight and fast-draining, nutrient-rich, soil with a neutral pH level. Regular care ensures Cuban oregano's health and success in a garden. -sfgate
