Its herbaceous, well-branched, procumbent growth habit results in a neat and dense rambling perennial shrub of about 1m high, rooting where the branches touch the ground. Like all members of the Lamiaceae family, the young branches are square in cross-section and the leaves are opposite. The dark green leaves are broadly ovate with 3-7 pairs of rounded teeth, slightly hairy to the touch both above and below and 35-40 mm in length.
