loose spikes from the summer to the early autumn.  Its leaves are dark green, oval, glossy and about 0.75 inches long.  It is used in herb gardens, as a mixed border, in containers, in dry areas, as a low hedge, a small topiary and for ground cover.  It is fire and deer resistive and provides pollen for bees.  It should be planted in poor to moderately fertile well drained soil and loves poor gritty soils.  It requires little water once established but a little more inland.  It should be planted in full sun because it gets leggy with less and pinch it back to keep a compact shape.  Shear back once or twice a year to force side branching.  It is a classic knot garden plant and tolerates routine shearing.  Set plants two feet apart for small scale ground cover.  It is hardy to 15 degrees Fahrenheit.
