This plant is growing wild in my yard. It gets partial shade during the first part of the day, followed by full sun in the afternoon. I thought it was part of the mint family due to the shape and placement of the leaves, but the stems are round, not squared. It is only around 4 inches in height. I'm not sure if it will continue to grow taller. It also sort of blankets the ground and is growing beside a bunch of clover and cranes bill.
