Grow in average, medium moisture, well-drained soil in full sun to part shade. Tolerant of full sun, drought and poor soils. Divide every 2-3 years to thin out planting and improve air circulation. Plants may be mowed on high setting after blooming in order to remove spent flower spikes and to tidy the appearance of the planting. An excellent groundcover for shady areas where grass will not grow. May also be grown on banks or slopes, under trees or around shrubs. Avoid planting adjacent to lawn areas since little islands of ajuga may start appearing in the grass.
